West Virginia Department of Environmental Protection (WV DEP) Division of Water and Waste Management regulatory frameworks, effluent standards, and enforcement timelines govern landfill discharge violations and 20-day compliance responses:
1. Specific Numeric Thresholds & Water Quality Standards
Under 47 C.S.R. § 2 (Requirements Governing Water Quality Standards) and 47 C.S.R. § 10 / § 30 (WV/NPDES Regulations), point-source discharges from solid waste landfills into surface waters (including tributaries feeding the Greenbrier River basin) are bound by the following numeric criteria:
| Parameter | Regulatory Standard (WV 47 C.S.R. § 2) | Benchmark / Permit Context | Violation Trigger |
| Mercury (Total Recoverable) | 0.012 µg/L (Chronic aquatic life protection; Category B) / 0.05 µg/L (Human Health / Public Water Supply, Category A) | Bioaccumulative neurotoxin; municipal landfill leachate carries strict non-detect or fractional microgram limits. | Any sample exceeding the monthly average or maximum daily permit limitation (often set at detection limit $\le 0.2\ \mu\text{g/L}$). |
| Chloride | 230 mg/L (Chronic aquatic life limit, 4-day average) / 860 mg/L (Acute 1-hour maximum) | Marker of concentrated landfill leachate and road/salt runoff. Directly increases stream conductivity and stresses freshwater macroinvertebrates. | Concentrations in discharge outlet or mixing zone exceeding 230 mg/L. |
| Dissolved Oxygen (DO) | Minimum 5.0 mg/L at all times (warmwater fishery); minimum 6.0 mg/L or 7.0 mg/L in designated trout waters. | High organic loading / chemical oxygen demand (COD) in leachate strips DO out of receiving streams. | Levels dropping below 5.0 mg/L (or below background baseline during low-flow periods). |
- Secondary Containment & Operational Triggers: Under 33 C.S.R. § 1 (Solid Waste Management Rule), active working face acreage limits, uncompacted refuse exposed beyond operating hours without 6 inches of approved daily cover, and uncontained 55-gallon petroleum/hydraulic oil drums constitute per-day operational violations independent of chemical effluent tests.
2. Legal Timelines: The 20-Day Response & Enforcement Ladder
When an Environmental Inspector issues a formal Notice of Violation (NOV) under W. Va. Code § 22-11 (Water Pollution Control Act) or W. Va. Code § 22-15 (Solid Waste Management Act), the clock begins running immediately upon service:
[Day 0: Service of NOV]
│
▼
[Day 1 to 20: Mandatory Corrective Action / Response Window]
• Permittee must submit written response to WV DEP Environmental Enforcement.
• Requires detailed Plan of Correction (abatement schedule, interim containment).
│
▼
[Post-Day 20 Evaluation by WV DEP]
┌─────────────────────────┴─────────────────────────┐
│ Submissions Accepted │ Inadequate or No Response
▼ ▼
[Follow-up Verification Inspection] [Administrative Escalation]
• Issuance of Administrative Order (AO)
• Assessment of Civil Administrative Penalties
(up to $25,000/day per violation)
• Consent Order with binding stipulated penalties
• Referral to WV Attorney General / Circuit Court
What Must Be in the 20-Day Written Response:
- Immediate Abatement Documentation: Evidence that temporary mitigations are active (e.g., secondary containment berms installed around fuel drums, daily cover applied, erosion/sediment traps cleared).
- Effluent Corrective Action Plan (CAP): Engineering narrative addressing how the leachate capture system or sedimentation basin will be altered to eliminate mercury, chloride, and low-DO discharges.
- Resampling Schedule: Submission of chain-of-custody test results from an accredited environmental laboratory showing return to compliance.
Enforcement Penalties & Appeals:
- Statutory Fines: Under W. Va. Code § 22-11-22, civil administrative penalties can be assessed up to $25,000 per day per violation, factoring in the degree of willfulness, economic benefit gained by non-compliance, and damage to aquatic resources.
- Administrative Appeal Window: If the DEP issues a formal unilateral Administrative Order following the 20-day review, the entity has 30 days to appeal the order to the West Virginia Environmental Quality Board (EQB) pursuant to W. Va. Code § 22B-1-7.
-----------------------------------------------------------------------------------
Converting an unlined or aging municipal solid waste (MSW) landfill into an operational solid waste transfer station in West Virginia requires navigating two distinct regulatory tracks concurrently under the WV DEP Division of Water and Waste Management (DWWM): formal facility closure (33 C.S.R. § 1, Section 6) and new transfer station permitting (33 C.S.R. § 1, Section 5), governed broadly by W. Va. Code § 22-15 (Solid Waste Management Act).
1. Required WV DEP Permits & Filings
A facility cannot simply "switch operations"; closure of the active disposal footprint and construction of the transfer facility require separate, enforceable permit modifications and authorizations:
- Landfill Closure Permit (Modification to Existing Solid Waste Facility Permit):
- Formal application for permanent cessation of waste disposal operations pursuant to 33 C.S.R. § 1-6.1.
- Initiates the binding transition from "active disposal facility" to "closed facility under post-closure care."
- Solid Waste Facility Permit for a Transfer Station:
- Application for a Class C (or applicable commercial transfer) facility permit under 33 C.S.R. § 1-5.
- Must establish that transfer operations will occur outside the unlined active fill footprint or on an engineered pad/building designed to prevent any commingling with underlying legacy waste.
- WV/NPDES Stormwater & Industrial Wastewater Permit Modification:
- Modification of existing water discharge permits under 47 C.S.R. § 10.
- Delineates separate outfalls: runoff from capped landfill areas (post-closure stormwater) versus leachate/wash-down water from the transfer building floor, tipping area, and compactor bays (which cannot discharge to surface waters and must be captured in closed holding tanks).
- Air Quality General Permit / Registration (WV DEP DAQ):
- If the transfer station incorporates stationary diesel generators, high-capacity shredders, or specialized odor-control ventilation units, a permit or registration under 45 C.S.R. § 13 may be required.
2. Engineering Milestones & Construction Standards
The conversion involves two parallel engineering scopes: constructing an impermeable cap over the existing landfill cells, and constructing a self-contained transfer infrastructure.
[Phase 1: Submittals] ───► [Phase 2: Landfill Cap] ───► [Phase 3: Transfer Facility] ───► [Phase 4: Certification]
• Closure/Post-Closure Plan • Grading & intermediate cover • Enclosed tipping floor • PE CQA Certification
• Hydrogeologic Eval. • Barrier layer (geomembrane) • Washdown containment tanks • WV DEP final inspection
• Transfer Station Siting • Gas venting & drainage net • Traffic routing / scales • Post-closure clock starts
A. Landfill Final Cap Engineering (33 C.S.R. § 1-6.2)
- Regrading & Subgrade Preparation: Reshaping slopes to a minimum 3% (to prevent ponding) and maximum 25% (or 4:1 / 3:1 with slope stability analysis) to prevent erosion and slope failure.
- Composite Cap Installation:
- Low-Permeability Barrier: Minimum 2-foot compacted clay layer ($k \le 1 \times 10^{-7}\text{ cm/sec}$) or an approved synthetic geomembrane (e.g., 60-mil HDPE or 40-mil LLDPE).
- Drainage Layer: Geocomposite drainage net or 6–12 inches of high-permeability sand.
- Vegetative Cover: Minimum 2 feet of clean rooting soil, with the top 6 inches capable of supporting native, non-woody, shallow-rooted perennial vegetation.
- Passive or Active Landfill Gas (LFG) Extraction: Installation of perforated collection wells and perimeter monitoring probes to prevent methane migration toward transfer station buildings.
- Surface Water Run-On/Run-Off Controls: Perimeter drainage benches, riprap-lined letdown channels, and detention basins designed for a 25-year, 24-hour storm event.
B. Transfer Station Infrastructure (33 C.S.R. § 1-5)
- Enclosed Tipping Floor & Structural Foundation: All dumping, sorting, and loading must take place on an impermeable concrete floor inside an enclosed structure or covered canopy to prevent rainfall contact.
- Leachate & Wash-Down Capture System: Floor drains, trench drains, and an oil-water separator leading to a dedicated double-walled holding tank or sealed collection vault. No tipping-floor wash-down may enter the surrounding karst soil or surface ditches.
- Traffic Flow & Weigh Station: Access roads with adequate sight distances, queuing lanes off public roads, and truck scales for gross/tare axle weighing.
3. Financial Assurance & Bonding Requirements
Under W. Va. Code § 22-15-12 and 33 C.S.R. § 1-13, financial assurance mechanisms must remain active and fully solvent before any operational transition can occur.
| Assurance Category | Statutory Mechanism | Calculation & Terms |
| Closure Bond | Surety bond, collateral bond, escrow agreement, or letter of credit payable to the State of WV. | Sized based on the third-party cost to cap the maximum acreage ever left open at one time (often ranging from $40,000 to $100,000+ per acre depending on site conditions, fill depth, and cap design). Released only after WV DEP approves the Professional Engineer’s Construction Quality Assurance (CQA) Final Report. |
| Post-Closure Care Bond | Dedicated financial assurance instrument maintained throughout the active care window. | Must cover 30 consecutive years of post-closure monitoring, including quarterly groundwater well sampling, landfill gas probe testing, leachate treatment/disposal, cap mowing, and erosion repairs. |
| Transfer Station Operational Bond | Performance bond for the transfer facility footprint. | Established under 33 C.S.R. § 1-13.3; calculated based on the cost of removing the maximum design storage capacity of unprocessed solid waste plus site decontamination in the event of default. |
Immediate Operational & Legal Verification Checklist
- Verify Solid Waste Management Plan Consistency: Check whether the local county Solid Waste Authority's comprehensive plan has been formally amended to replace disposal acreage with a transfer station and that it aligns with the West Virginia Solid Waste Management Board (SWMB) siting guidelines.
- Review Groundwater Monitoring Network: Verify that existing monitoring wells are structurally sound and not damaged by regrading. At least one upgradient and three downgradient monitoring wells must be maintained for the full 30-year post-closure lifecycle.
- Confirm Leachate Disposal Interlocal Agreement: Secure a certified municipal sewage treatment facility or industrial disposal site willing to accept high-COD/chloride leachate pumped from the transfer sump and closed-cell tanks.

------------------------------------------------------------------------------------------------------------------
Under the West Virginia Solid Waste Management Rule (33 C.S.R. § 1, Section 6 for closure/post-closure and Section 4.11 for groundwater monitoring), post-closure groundwater monitoring is an enforceable 30-year statutory requirement.
The regulatory framework divides monitoring into three distinct tiers: Phase I Detection Monitoring, Phase II Assessment Monitoring, and Corrective Action.
1. Monitoring Phases & Analytical Parameters (33 C.S.R. § 1-4.11)
[Phase I: Detection Monitoring]
│ (Appendix I Inorganics & VOCs)
▼
[Statistically Significant Increase (SSI)?]
├─► NO ──► Continue Baseline Detection Cycle
└─► YES ──► Resample within 14–30 days
│
▼ (SSI Confirmed)
[Phase II: Assessment Monitoring]
│ (Appendix II Full Hazardous Constituent Suite)
▼
[Exceeds Groundwater Protection Standard (GWPS)?]
├─► NO ──► Remain in Phase II
└─► YES ──► Formulate Corrective Action Plan (CAP)
A. Phase I Detection Monitoring (Default Post-Closure Suite)
All monitoring wells (upgradient background and downgradient compliance points) are tested for Appendix I constituents:
- Field / Indicator Parameters: Groundwater elevation (static water level before purging), pH, specific conductance, temperature, and turbidity.
- General Chemistry & Leachate Indicators: Total Dissolved Solids (TDS), Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Total Organic Carbon (TOC), Ammonia-Nitrogen ($\text{NH}_3\text{-N}$), Chloride ($\text{Cl}^-$), and Sulfate ($\text{SO}_4^{2-}$).
- Total Recoverable Metals (15 inorganic elements): Antimony, Arsenic, Barium, Beryllium, Cadmium, Chromium, Cobalt, Copper, Lead, Nickel, Selenium, Silver, Thallium, Vanadium, and Mercury ($\text{Hg}$).
- Volatile Organic Compounds (VOCs): 47 organic constituents (including benzene, toluene, ethylbenzene, xylenes, vinyl chloride, tetrachloroethylene [PCE], and trichloroethylene [TCE]).
B. Phase II Assessment Monitoring (Triggered Suite)
If a statistically significant increase (SSI) over background is confirmed for any Phase I parameter:
- The testing scope expands to Appendix II (comprising over 200 parameters, including semi-volatile organic compounds [SVOCs], polycyclic aromatic hydrocarbons [PAHs], pesticides, herbicides, PCBs, and dioxins/furans).
- Groundwater Protection Standards (GWPS): DEP establishes numeric GWPS limits for detected constituents based on Maximum Contaminant Levels (MCLs) or health-based risk numbers.
2. Sampling Frequency & Post-Closure Schedule
| Monitoring Type | Regulatory Frequency (33 C.S.R. § 1-4.11 & § 1-6) | Operational Requirements |
| Phase I (Detection) | Semiannually (twice per year) minimum; quarterly during baseline establishment. | Permittee may petition the DEP Secretary to reduce frequency after several consecutive clean cycles, but twice per year is the operational standard for unlined legacy facilities. |
| Phase II (Assessment) | Semiannually for all detected Appendix II constituents; annually for the entire Appendix II catalog. | Includes mandatory sampling of all downgradient compliance wells and sensitive drinking water supply points within the defined zone of transport. |
| Well Inspections & Water Levels | At every sampling event (and monthly general site inspections under § 1-6.4). | Static water level recorded to nearest 0.01 foot prior to pump deployment to establish potentiometric surface and seasonal flow vectors. |
3. Reporting Rules, Deadlines & Verification Protocols
- Submission Deadlines: Sampling reports must be submitted to the WV DEP Division of Water and Waste Management (DWWM) within 60 days of completing laboratory analysis, certified by a West Virginia P.E. or certified professional geologist.
- Statistical Analysis Requirement (33 C.S.R. § 1-4.11.g):
- Raw numbers cannot simply be eyeballed. The permittee must perform approved statistical evaluations (e.g., ANOVA, tolerance intervals, prediction intervals, or control charts) to determine whether a downgradient well exhibits an SSI over upgradient background wells.
- Notification of Exceedance:
- If an SSI is identified, the permittee must place a notice in the facility operating record immediately and notify the WV DEP Director in writing within 14 days, identifying the specific constituents that exceeded baseline.
- The facility has 30 days to resample the well network to confirm or refute the finding.
- 30-Year Clock Management (33 C.S.R. § 1-6.4):
- The 30-year clock begins only after WV DEP formally approves the Professional Engineer’s Construction Quality Assurance (CQA) Final Closure Certification.
- Automatic Clock Extension: If a facility enters Phase II Assessment Monitoring or Corrective Action during post-closure, the 30-year period does not expire until the groundwater returns to compliance with GWPS across all points for three consecutive years without active intervention.
Immediate Oversight Checklist for Compliance Records
- Audit Semi-Annual DMRs: Pull the semi-annual Groundwater Monitoring Reports (GMRs) and Discharge Monitoring Reports (DMRs) on file with the DEP for the last 5 years.
- Review Upgradient vs. Downgradient Spreads: Compare upgradient background well concentrations of chloride, conductivity, and dissolved metals against downgradient wells bordering local drainage channels.
- Check Certified Lab Methods: Verify that mercury was analyzed using low-level EPA Method 1631E (capable of detecting sub-microgram levels) rather than less sensitive methods that mask low-level plumes above state chronic aquatic thresholds ($0.012\ \mu\text{g/L}$).
------------------------------------------------------------------------
In mature karst limestone aquifers, conventional porous-media hydrogeology (Darcy’s Law) breaks down completely. Water and contaminants do not seep uniformly through sand and gravel at inches per day; instead, they flow through dissolution conduits, enlarged bedding planes, and subterranean cave networks at velocities matching surface streams—often hundreds to thousands of feet per day.
Fluorescent dye tracing is the hydrogeologic standard for establishing direct, empirical source-to-receptor connections, proving groundwater flow paths, and measuring conduit transit velocity.
1. Tracer Selection & Chemical Properties
Tracer dyes must be water-soluble, detectable at parts-per-trillion (ppt) concentrations, non-toxic to humans and aquatic organisms at test dilutions, and chemically stable against degradation by natural organic matter.
- Uranine (Sodium Fluorescein): The most common green tracer. Very high fluorescence intensity, detectable down to 0.005 ppb. Moderately susceptible to photochemical degradation in direct sunlight, making it ideal for underground conduit tracing. Excitation: ~491 nm; Emission: ~512 nm.
- Eosine (Acid Red 87): An orange-red dye with low background interference. Often used in multi-tracer tests simultaneously with Fluorescein. Excitation: ~518 nm; Emission: ~538 nm.
- Rhodamine WT (Acid Red 388): Highly resistant to sunlight and microbial breakdown, used extensively for both surface water mixing and groundwater conduits. It binds slightly more to fine clays and organic silts than Uranine. Excitation: ~556 nm; Emission: ~580 nm.
- Optical Brighteners (Tinopal CBS-X): Fluorescent whitening agents that fluoresce in the blue spectrum under ultraviolet light. Often used in household detergents; useful as a secondary tracer where background detergent levels are low.
2. Experimental Design & Field Execution
Executing a valid dye trace requires strict chain-of-custody protocols and clean handling to prevent false positives from surface cross-contamination.

A. Baseline Sampling (Background Control)
Before any tracer is brought to the study area, passive monitoring packets must be placed at all proposed recovery stations (receptor drinking wells, downgradient springs, tributary streams) for 7 to 14 days. This establishes natural background fluorescence caused by decaying vegetation, algae, or domestic laundry discharge.
B. Injection Protocol
- Selection of Point: Injected into a known sinkhole swallet, open rock fissure, sinking stream reach, or dry monitoring well drilled into bedrock voids.
- Water Flush: A rapid injection of dye alone is insufficient in dry karst conduits. A calculated volume of tanker-truck "chase water" (typically 1,000 to 10,000+ gallons) must follow immediately to propel the tracer past the soil epikarst zone and push it directly into active conduit circulation.
- Cross-Contamination Shielding: Field technicians handling the concentrated dye powder or liquid must not visit or touch any downstream monitoring stations. Monitoring equipment and recovery personnel remain strictly isolated from injection gear.
C. Recovery Stations
- Passive Charcoal Receptors ("Bugs"): Small packets of granular coconut-shell activated charcoal inside fiberglass or wire mesh. Charcoal continuously adsorbs and concentrates organic dyes from passing water over days or weeks, capturing pulses that might pass between grab-sampling intervals.
- Automated Water Samplers (ISCO Units): Programmed to pull discrete grab samples at hourly intervals to construct a precise breakthrough curve.
- Direct Fluorometers: Submersible optical probes deployed in wells or spring pools logging real-time fluorescence and temperature at 5- to 15-minute intervals.
3. Laboratory Analysis & Interpretation
Elution & Spectrofluorometric Analysis
Charcoal packets are retrieved, rinsed clean of sediment with distilled water, and soaked in an eluent—typically a basic alcohol solution such as Smart Solution (1-propanol, ammonium hydroxide, and distilled water). The eluent strips the adsorbed dye into solution.
The liquid is analyzed on a luminescence spectrometer (spectrofluorophotometer) running a synchronous scan (excitation and emission monochromators scanned simultaneously at a fixed wavelength interval, typically $\Delta\lambda = 17\text{ nm}$).
- Peak Verification: A positive hit requires a distinct fluorescence peak occurring within $\pm 2\text{ nm}$ of the certified dye standard (e.g., Fluorescein peak at ~512 nm). A broad, ill-defined rise indicates organic interference; a sharp, narrow peak demonstrates presence of the dye.
- Signal-to-Background Ratio: Regulators typically require a peak intensity at least three times higher than background levels to certify a definitive hydraulic connection.
Constructing the Breakthrough Curve
| Curve Characteristic | Hydrogeologic Interpretation |
| First Arrival Time ($t_0$) | Marks the fastest possible transit time through the major dissolution conduit. |
| Peak Concentration Time ($t_p$) | Represents the mean groundwater velocity along the primary flow path ($v = \text{Distance} / t_p$). |
| Leading Edge Slope | A steep rising limb indicates open, free-flowing conduit flow with minimal sediment storage. |
| Trailing Limb & Tail | A prolonged, asymmetric tail indicates dispersion into small fracture networks, storage in sediment banks, or eddy zones within cave passages. |
| Multiple Peaks (Bimodal) | Proves bifurcation of groundwater flow—the plume split through two separate cave passages or subterranean conduits before converging at the spring or well. |
4. Regulatory Application: Proving Contaminant Transport
In environmental enforcement and landfill permitting:
- Overriding Surface Topography: Dye traces routinely prove that groundwater travels underneath topographic surface ridges, discharging into an adjacent watershed contrary to surface drainage divides.
- Time-of-Travel (TOT) Zones: Demonstrates whether a potential leachate or spill source sits within a public wellhead's critical 1-year or 5-year capture zone.
- Establishing Liability: Unambiguously links an upgradient source (such as an unlined landfill cell or industrial spill) to downgradient drinking water wells or trout stream outfalls, transforming a theoretical hydrogeologic risk into an empirical legal fact.
-----------------------------------------------------------------------------------
Hydrogeologic Fluorescent Dye Tracing Work Plan & Monitoring Protocol
Target Corridor: 1.0-Mile Karst Valley Corridor (Upgradient Potential Source Area to Downgradient Sensitive Receptors / Public Wells / Springs)
Regulatory Standards: West Virginia Department of Environmental Protection (WV DEP) Division of Water and Waste Management (DWWM); EPA Karst Groundwater Monitoring Technical Guidance (EPA/600/R-89/050).
1. Scope, Objectives & Hydrogeologic Setting
- Objective: Establish whether an active, direct subterranean conduit connection exists across the 1-mile corridor, calculate groundwater velocity (first arrival $t_0$ and peak $t_p$), and define the time-of-travel (TOT) capture zone relative to downstream drinking water wells and surface springs.
- Site Hydrogeology: Soluble carbonate bedrock (limestone/dolomite). The conceptual model assumes triple-porosity flow: matrix block storage, secondary joint/fracture networks, and tertiary dissolution conduits/caves. Flow velocities are assumed to range from $100\text{ ft/day}$ to over $5,000\text{ ft/day}$ under base-flow conditions.
2. Tracer Selection & Mass Loading Calculations
To prevent visible staining at public water taps while guaranteeing spectrofluorophotometric detection above analytical limits of quantitation (LOQ $\approx 0.005\ \mu\text{g/L}$), dye mass is sized using the standardized karst transport equation (Worthington & Smart, 2003):
$$M = 1.9 \times 10^{-5} \cdot (L \cdot Q \cdot C_p)^{0.5}$$
Where:
- $M$ = Mass of pure dye ($\text{kg}$)
- $L$ = Straight-line straight distance ($1.0\text{ mile} \approx 1,609\text{ m}$)
- $Q$ = Total estimated spring/wellfield discharge ($\text{L/s}$)
- $C_p$ = Target peak concentration ($\mu\text{g/L}$, maintained $\le 10\ \mu\text{g/L}$ to stay beneath drinking water aesthetic thresholds)
- Primary Tracer: Uranine / Sodium Fluorescein (Acid Yellow 73; CAS# 518-47-8). High fluorescence yield, low adsorption to clay, analytical peak at $\approx 512\text{ nm}$.
- Secondary / Divergent Tracer (Multi-Point Injection): Eosine (Acid Red 87; CAS# 17372-87-1), analytical peak at $\approx 538\text{ nm}$, or Rhodamine WT (Acid Red 388), analytical peak at $\approx 580\text{ nm}$.
3. Monitoring Network & Receptor Deployment
Receptors will be deployed at five designated stations along the 1-mile reach:
- Station MP-1 (Target Receptor): Downgradient Public / School Supply Well (raw water tap prior to chlorination/filtration).
- Station MP-2 (Primary Spring Outflow): Main valley resurgence spring feeding the tributary stream.
- Station MP-3 (Secondary Outcrop / Cave Stream): Upstream resurgence or side-valley insurgence.
- Station MP-4 (Surface Water Boundary): Downgradient perennial stream confluence (mixing zone).
- Station MP-5 (Upgradient / Cross-Gradient Control): Distant spring outside the projected conduit path (quality assurance negative control).
Monitoring Equipment:
- Passive Charcoal Receptors ("Bugs"): Heat-sealed fiberglass/wire mesh packets containing 10–12 grams of 6×12 mesh, activated coconut-shell charcoal suspended on stainless steel wire and secured with non-reactive lead/brick anchors.
- Automated Water Samplers (ISCO 6712): Deployed at Stations MP-1 and MP-2, programmed to collect 500 mL grab samples into high-density polyethylene (HDPE) amber bottles.
- Multi-Parameter Data Loggers: Continuously recording conductivity, temperature, and water stage at 15-minute intervals to correct for dilution and recharge pulses.

- Chaser Volume: Immediately flushed with 3,000 to 5,000 gallons of clean water delivered via tanker truck at $\approx 200\text{ gpm}$ to drive the dye past the residuum and into the primary saturated conduit network.
- Contamination Segregation: Personnel handling dye concentrate are strictly prohibited from visiting sampling stations or touching recovery gear for the remainder of the study.
5. Detailed Sampling Schedule (28-Day Window)

6. Laboratory Extraction & Spectrofluorometric Analysis
- Decontamination & Elution: Charcoal packets are retrieved, washed with organic-free deionized water under a laminar flow hood to remove silt, and placed into dedicated, sealed borosilicate glass vials.
- Eluting Solvent: 10 mL of Smart Solution (5 parts 1-propanol, 3 parts concentrated ammonium hydroxide, 2 parts distilled water) is pipetted over the charcoal and soaked for 60 minutes in darkness.
- Instrumentation: Analysis performed on a dual-monochromator Luminescence Spectrophotometer utilizing synchronous scan mode with a fixed excitation/emission separation ($\Delta\lambda = 17\text{ nm}$).
- Positive Determination Criteria:
- Emission peak must match the calibrated tracer standard within $\pm 2.0\text{ nm}$.
- Fluorescent intensity of the sample must exceed the pre-injection baseline background by a minimum factor of three ($3\times$).
- The peak shape must exhibit a typical Gaussian distribution rather than a broad, sloping background signature.

- Mean Conduit Velocity: $v_{\text{mean}} = \frac{\text{Direct Distance}}{t_p}$ (Peak arrival).
- Mass Recovery Percentage: Integrated area under the breakthrough curve multiplied by discharge ($Q$) divided by total injected mass ($M$) to determine capture efficiency.
- Final P.E. Certified Report: Includes hydrogeologic cross-sections, calibration sheets, instrument spectra overlays, and a delineated Karst Wellhead Protection Area map submitted directly to the WV DEP and county authorities.
--------------------------
1. Mathematical Framework & Empirical Equations
In karst conduit aquifers, dye mass sizing must ensure the peak breakthrough concentration ($C_p$) exceeds the laboratory Limit of Quantitation (LOQ $\approx 0.005\ \mu\text{g/L}$ or $\text{ppb}$) while remaining well below the visual threshold ($C_{\text{visual}} \approx 10\text{ to }20\ \mu\text{g/L}$) to prevent public discoloration at taps or recreational waters.
The standard empirical formulation established by Worthington & Smart (2003) for sinkhole-to-spring conduit flow is:
$$M = 19 \cdot (L \cdot Q \cdot C_p)^{0.95}$$
Where:
- $M$ = Required mass of dry tracer (pure Sodium Fluorescein / Uranine) in grams ($\text{g}$)
- $L$ = Straight-line distance from injection point to receptor in meters ($\text{m}$) ($1.0\text{ mile} = 1,609.34\text{ m}$)
- $Q$ = Total discharge of the groundwater system at the recovery points in cubic meters per second ($\text{m}^3/\text{s}$)
- $C_p$ = Target peak breakthrough concentration in grams per cubic meter ($\text{g/m}^3$), which is equivalent to $\text{mg/L}$ or $1,000\ \mu\text{g/L}$
2. Parameter Conversion & Baseline Scenarios
To calculate $Q$, the total down-gradient flow is the sum of the pumping well yield ($Q_{\text{well}}$) and the receiving tributary/spring baseflow discharge ($Q_{\text{spring}}$):
$$Q = Q_{\text{well}} + Q_{\text{spring}}$$
- Conversion factors:
- $1\text{ gpm} = 0.00006309\ \text{m}^3/\text{s}$
- $1\text{ cfs} (\text{ft}^3/\text{s}) = 0.028317\ \text{m}^3/\text{s}$
- Target Peak Concentration: $C_p = 5.0\ \mu\text{g/L} = 0.005\ \text{g/m}^3$ (provides an analytical signal $1,000\times$ above the instrument detection limit while remaining invisible to the human eye).
Scenario Comparison Across Karst Hydrologic Conditions
| Parameter | Scenario A: Low-Flow Baseflow (Late Summer / Fall) | Scenario B: Moderate Baseflow (Spring Transition) | Scenario C: High-Flow Event (Post-Precipitation) |
| Distance ($L$) | $1,609.34\text{ m}$ (1.0 mile) | $1,609.34\text{ m}$ (1.0 mile) | $1,609.34\text{ m}$ (1.0 mile) |
| Well Pumping Rate ($Q_{\text{well}}$) | $100\text{ gpm}$ ($0.0063\ \text{m}^3/\text{s}$) | $150\text{ gpm}$ ($0.0095\ \text{m}^3/\text{s}$) | $200\text{ gpm}$ ($0.0126\ \text{m}^3/\text{s}$) |
| Spring / Stream Baseflow ($Q_{\text{spring}}$) | $0.50\text{ cfs}$ ($0.0142\ \text{m}^3/\text{s}$) | $2.00\text{ cfs}$ ($0.0566\ \text{m}^3/\text{s}$) | $6.00\text{ cfs}$ ($0.1699\ \text{m}^3/\text{s}$) |
| Combined System Discharge ($Q$) | $0.0205\ \text{m}^3/\text{s}$ (~325 gpm) | $0.0661\ \text{m}^3/\text{s}$ (~1,048 gpm) | $0.1825\ \text{m}^3/\text{s}$ (~2,893 gpm) |
| Target Peak ($C_p$) | $0.005\ \text{g/m}^3$ ($5\ \mu\text{g/L}$) | $0.005\ \text{g/m}^3$ ($5\ \mu\text{g/L}$) | $0.005\ \text{g/m}^3$ ($5\ \mu\text{g/L}$) |
| Product ($L \cdot Q \cdot C_p$) | $1,609.34 \cdot 0.0205 \cdot 0.005 = 0.1650$ | $1,609.34 \cdot 0.0661 \cdot 0.005 = 0.5319$ | $1,609.34 \cdot 0.1825 \cdot 0.005 = 1.4685$ |
| Pure Dry Dye Mass ($M_{\text{dry}}$) | $19 \cdot (0.1650)^{0.95} \approx \mathbf{3.45\text{ g}}$ | $19 \cdot (0.5319)^{0.95} \approx \mathbf{10.45\text{ g}}$ | $19 \cdot (1.4685)^{0.95} \approx \mathbf{27.35\text{ g}}$ |
| Recommended Field Mass (35% Purity or Safety Margin) | $50\text{ to }100\text{ g}$ | $150\text{ to }250\text{ g}$ | $400\text{ to }600\text{ g}$ |
(Note: Standard commercial Sodium Fluorescein is typically supplied either as technical-grade powder [~75% active dye] or 20% to 35% liquid concentrate. Field mass must be scaled by dividing $M_{\text{dry}}$ by the manufacturer’s certified active dye percentage. In practice, regulatory work plans round upward to standard pre-weighed increments [e.g., 100 g or 250 g] to account for non-conduit dispersion and epikarst storage losses.)
3. Injection Water Chase Volume Requirements
In an epikarst setting, dry swallets, sinkholes, and shallow recharge features hold substantial unsaturated pore storage (soil moisture deficit and capillary fringe). Injecting tracer without sufficient flush leaves the dye stranded above the water table until a major rain event occurs, compromising travel-time calculations.
The total water volume required comprises two sequential stages:
[Stage 1: Pre-Wet Slug] ────────► [Stage 2: Dye Introduction] ────────► [Stage 3: High-Rate Chase Flush]
1,000 to 1,500 gal Dissolved dye slug poured into 3,000 to 5,000 gal pumped at
Saturates dry epikarst active throat of swallet. ≥150–250 gpm to push tracer
soil & satisfies storage. into open phreatic conduits.
Analytical Chase Sizing:
- Pre-Injection Wetting Volume ($V_{\text{pre}}$):
- $1,000\text{ to }1,500\text{ gallons}$ delivered 15–30 minutes prior to dye injection.
- Purpose: Saturates clay/silt residuum in the swallet throat, lubricates conduit walls, and creates an artificial downward hydraulic head.
- Post-Injection Chaser Volume ($V_{\text{chase}}$):
- Sized using conduit displacement volume over the immediate entrance zone:$$V_{\text{chase}} = \pi \cdot r_{\text{conduit}}^2 \cdot L_{\text{entry}}$$
- For an estimated average throat diameter of 1.5 ft ($r = 0.75\text{ ft}$) over a 200-ft entry reach:$$\text{Volume} = 3.1416 \cdot (0.75)^2 \cdot 200 = 353.4\ \text{ft}^3 \approx 2,644\ \text{gallons}$$
- Adding a 1.5× safety factor yields $3,500\text{ to }4,000\text{ gallons}$.
- Pumping Rate & Delivery Head:
- Water must not be gravity-dribbled. A dedicated water tender equipped with a 2.5-inch or 3-inch discharge line must pump the chase water at a minimum delivery rate of $150\text{ to }250\text{ gpm}$.
- High discharge creates the critical localized hydraulic pressure head needed to force the dye slug past sediment-clogged pinch points and into the primary saturated conduit network.
4. Interactive Dye Mass & Chase Volume Calculator
Immediate Field Preparation Steps
- Conduct Water Source Pre-Screening: Verify that the bulk water tender used for the 5,000-gallon chase is drawn from a municipal non-chlorinated spring or untreated river source, or has been thoroughly dechlorinated (residual chlorine strips and oxidizes fluorescein dye, quenching fluorescence before it reaches the conduit).
- Prepare Secondary Containment at Mixing Point: Mix the dry dye into 5-gallon carboys with clean water off-site inside a controlled facility, transporting only liquid dye solutions to the field site to prevent airborne powder drift from contaminating downstream charcoal monitoring traps.
--------------------------------------
Under the West Virginia Bureau for Public Health (WVBPH) legislative rule General Sanitation (W. Va. Code R. § 64-18), read in conjunction with Public Water Systems (64 C.S.R. § 3) and Cross-Connection Control and Backflow Prevention (64 C.S.R. § 15), public and institutional schools are legally classified as non-transient non-community public water systems (NTNCWS) if they serve $\ge 25$ of the same individuals daily from an on-site well.
When groundwater contamination or an imminent health hazard triggers a "Do Not Drink / Do Not Use" order from the local health officer or the State Health Officer, strict mandates govern both emergency hauled water and point-of-use (POU) filtration installations.
1. Bulk & Hauled Water Regulations (W. Va. Code R. § 64-18-23.9)
Under § 64-18-23.9, the Commissioner of the Bureau for Public Health or local health officer may authorize potable water transported in tanks either to supplement an existing supply or serve as the sole water source during an emergency.
- Approved Source Required (§ 64-18-23.9.a): Hauled water must be drawn exclusively from an approved public water system (e.g., a certified municipal utility tap). Hauling from unpermitted private wells, unregulated surface intakes, or agricultural fill stations is strictly illegal.
- Mandatory Disinfectant Residual (§ 64-18-23.9.a): Water transported in tanks must maintain at least 1.0 mg/L (ppm) free chlorine residual (or an equivalent approved disinfectant) at all times.
- Disinfection Protocol: Haulers add approximately 3 liquid ounces of 6% sodium hypochlorite (unscented household bleach) per 1,000 gallons of water to offset organic chlorine demand and ensure the 1.0 mg/L threshold is sustained during transit and transfer.
- Tanker Specifications & Prior Use Documentation (§ 64-18-23.9.b / WVBPH OEHS Standards):
- Dedicated Service Labeling: The transport tanker must be clearly, permanently, and conspicuously stenciled on both sides and the rear with: "DRINKING WATER ONLY" (minimum 3- to 4-inch block lettering).
- Prior-Use Exclusions: Tankers that have previously carried petroleum products, chemicals, raw milk, wastewater, or toxic materials are permanently barred from being retrofitted for potable hauling. Tankers must have certified documentation verifying food-grade stainless steel or NSF/ANSI 61-certified interior linings.
- Sanitary Offloading: Hoses must be food-grade, smooth-bore, equipped with capped fittings when not in use, and offloaded using an air gap or certified backflow preventer.
- Storage & Daily Monitoring Logs:
- If hauled water is transferred into an on-site atmospheric holding tank or bladder, the tank must be sanitized with a 50 mg/L chlorine solution prior to filling, sealed against insects/dust, and vented with a downward-facing fine-mesh screen.
- School facilities staff or the licensed certified water operator must log free chlorine residual and temperature at least once daily prior to campus building distribution.
2. Point-of-Use (POU) & Fixture Controls (§ 64-18-23.4 – 23.7)
If the school well remains online for non-potable utility purposes (e.g., boiler operation, toilet flushing) while contaminated with heavy metals (mercury) or industrial volatile compounds, physical isolation of drinking access points is legally required:
[Contaminated Well Head]
│
├──► [Sanitary Fixtures: Toilets / Urinals] ──► Direct Well Feed Allowed (Non-Potable)
│
└──► [Taps / Sinks / Fountains (Potable Access)]
│
├──► [Physical Decommissioning]: Bubble caps taped / handles locked out
└──► [Certified Point-of-Use (POU)]: NSF/ANSI 58 (RO) or NSF/ANSI 53 (Metals)
- Drinking Fountains & Common Dispensers (§ 64-18-23.4, § 64-18-23.5):
- All common drinking fountains supplied by the unapproved/compromised supply must be taken out of service immediately (physically disconnected, bagged, and tagged with "DO NOT DRINK" warning signs).
- Common dipping vessels or cups are prohibited (§ 64-18-23.5). Disposable single-service cups must be dispensed from sanitary enclosed wall units (§ 64-18-23.6).
- Portable Coolers / Bottled Water Stations (§ 64-18-23.7):
- Where portable 5-gallon coolers or bottled-water stations are deployed in hallways and cafeterias, they must be securely closed, constructed of non-toxic, easily cleanable materials, and dispensed solely through a sanitary tap or push-button faucet (§ 64-18-23.7).
- Coolers must be sanitized between refills, kept on elevated stands (never placed on bare ground or floors), and handled strictly under hygienic food-service protocols.
3. Engineering & Treatment Standards for POU/POE Treatment
Under 64 C.S.R. § 3 and WVBPH Environmental Engineering Division (EED) policy, installing Point-of-Use (POU) or Point-of-Entry (POE) filtration in a public school requires an Engineering Permit (Form EW-102) signed by a licensed West Virginia P.E. before installation:
| Target Contaminant | Mandatory Certification Standard | Required Technology & Redundancy |
| Total Mercury & Heavy Metals | NSF/ANSI Standard 58 (Reverse Osmosis) or NSF/ANSI Standard 53 (Health Effects / Metals Adsorption) | Multi-stage RO with pre-sediment filtration and specialized KDF-55 or thiol-functionalized carbon blocks capable of reducing inorganic mercury below the $0.002\text{ mg/L}$ MCL. |
| Volatile Organic Compounds (VOCs) / Solvents | NSF/ANSI Standard 53 | Dual granular activated carbon (GAC) beds installed in series with intermediate testing ports to monitor breakthrough before saturation. |
| Microbiological / Surface Water Infiltration (GWUDI) | NSF/ANSI Standard 55 (Class A) | Ultraviolet disinfection providing minimum dose of $40\text{ mJ/cm}^2$, equipped with automatic shut-off solenoid valves if UV transmittance (UVT) drops below threshold. |
- Maintenance & Auto-Shutoff: Any POU filter installed at school kitchen prep sinks must feature an automatic shut-off mechanism that stops water flow when the rated gallon capacity is reached, preventing filter bypass under exhausted conditions.
4. Backflow Isolation & Plumbing Interface (W. Va. Code R. § 64-18-14 & 64 C.S.R. § 15)
To prevent cross-contamination between emergency hauled water and contaminated groundwater:
- Physical Air Gap: If hauled water is pumped into an existing plumbing cistern or gravity reservoir, the inlet pipe must maintain an unobstructed vertical distance of at least two pipe diameters (minimum 2 inches) above the flood-level rim of the receiving tank.
- Complete Separation: Cross-connections between a raw contaminated well line and an auxiliary hauled water line are prohibited. Physical disconnect (spool removal or blind flanging) is required; relying on a closed gate or ball valve does not satisfy state cross-connection rules.
- Food Service Hot Water (§ 64-18-23.3): Emergency water systems must maintain adequate pressure and volume to deliver hot water at not less than 110°F to all cafeteria dishwashing and food-preparation sinks, or the school kitchen must transition entirely to single-service pre-packaged items and disposable utensils.
--------------
The EPA Hazard Ranking System (HRS, codified at 40 C.F.R. Part 300, App. A) is the principal screening mechanism used under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) to place hazardous waste sites on the National Priorities List (NPL).
A site scoring $\ge 28.50$ across its evaluated pathways qualifies for Superfund listing. When drinking water wells—whether municipal, school, or private residential—are located within a 1-mile radius of an unlined or leaking solid waste landfill, the Ground Water Migration Pathway ($S_{gw}$) typically drives the total score above this listing threshold.
1. The Ground Water Migration Pathway Equation
Under Section 3.0 of the HRS, the ground water pathway score ($S_{gw}$) is calculated by multiplying three core factor categories:
$$S_{gw} = \frac{\text{Likelihood of Release (LR)} \times \text{Waste Characteristics (WC)} \times \text{Targets (T)}}{82,500}$$
(The product is normalized to a 0–100 scale using the statutory divisor of 82,500.)
[Likelihood of Release (LR)] ───► Maximum 550 pts (Observed Release = 550)
│
▼
[Waste Characteristics (WC)] ───► Up to 100 pts (Toxicity, Persistence, Quantity)
│
▼
[Targets (T)] ───► Evaluates Populations within 1-Mile & 4-Mile TDL
│ ├─ Actual Contamination (Level I / Level II)
│ └─ Potential Contamination (Distance-Weighted)
▼
Total Ground Water Pathway Score (Sgw) ──► If Sgw ≥ 57.0, Site Score Exceeds 28.50
2. Likelihood of Release (LR): Observed Release vs. Potential to Release
The HRS divides the likelihood of release into two mutually exclusive branches:
- Observed Release (Assigned Maximum Score = 550):
- An observed release is established if analytical data from a drinking water well or compliance monitoring well demonstrates a contaminant concentration significantly above background levels (at least $3\times$ background if background is above detection, or equal to/greater than the sample quantitation limit if background is non-detect).
- The release must be attributed at least in part to the landfill (e.g., leachate indicator matches such as mercury, chloride ratios, or volatile organics).
- Result: If an observed release is documented in groundwater, LR is automatically assigned the maximum possible 550 points, bypassing soil permeability and depth-to-aquifer modeling entirely.
- Potential to Release (If No Direct Hit Yet, Max = 500):
- Evaluated via net precipitation, depth to shallowest aquifer, and hydraulic conductivity. In fractured limestone/karst terrain, the hydraulic conductivity factor is assigned the maximum value ($10^{-2}\text{ to }10^{-1}\text{ cm/s}$), pushing Potential to Release close to 500 points even without confirmed well impacts.
3. Waste Characteristics (WC): Toxicity, Mobility, & Volume
Waste Characteristics evaluate the chemical hazard of the materials disposed of or detected:
- Toxicity / Mobility: Each detected hazardous substance is assigned a combined matrix score (0 to 10,000).
- Mercury ($\text{Hg}$): Toxicity factor of 10,000; in water, persistent heavy metals carry maximum persistence/mobility values.
- Chlorinated Solvents (TCE, PCE, Vinyl Chloride): High toxicity and volatility/mobility in karst conduits.
- Hazardous Waste Quantity (HWQ): Sized based on the physical volume of the landfill or mass of uncontained waste. Landfills exceeding 100,000 cubic yards or with documented uncontained drum storage easily reach high-tier HWQ values.
- Pathway Waste Characteristics Factor: Scaled logarithmically from the combined toxicity/quantity product, commonly yielding 32 to 100 points.
4. Targets (T): Evaluating Drinking Wells within 1 Mile
The Targets factor category is where a 1-mile proximity to high-occupancy drinking water wells generates significant points. The HRS evaluates targets within a 4-mile Target Distance Limit (TDL) from the site boundary, categorizing them into three tiers:
| Target Category | Criteria & Thresholds | Scoring Multipliers | Impact on 1-Mile Wells |
| Actual Contamination: Level I | Contaminant concentration in a drinking water well meets or exceeds health-based benchmarks (e.g., EPA Maximum Contaminant Level [MCL] or drinking water screening levels). | Population $\times 10$ (Direct $10\times$ multiplier applied to the target population). | If a public school well (e.g., serving 500 students/staff) or cluster of municipal wells exceeds the $0.002\text{ mg/L}$ MCL for mercury or $5.0\ \mu\text{g/L}$ for PCE, the Level I points alone can push the site past the 28.50 cutoff. |
| Actual Contamination: Level II | Contaminants detected significantly above background, but below health-based benchmarks (e.g., low-level detect below MCL). | Population $\times 1$ (Standard 1:1 population weighting). | Captures early-stage plumes entering private residential or institutional wells before dangerous thresholds are crossed. |
| Potential Contamination | Wells within the 4-mile TDL that are completed in the same aquifer but not yet contaminated. | Population is weighted using a Distance-Weighted Matrix. | The 0 to 1/4 mile and 1/4 to 1/2 mile bands carry the highest potential weighting factors ($0.1$ to $0.05$ per capita), decreasing exponentially out to 4 miles. |
Special Target Multipliers:
- Nearest Well Factor: If a drinking water well is within the 1-mile perimeter:
- Assigned 50 points (maximum) for Level I contamination.
- Assigned 45 to 50 points for Level II.
- Assigned 20 points for potential contamination within 1/4 mile.
- Wellhead Protection Areas (WHPA): If the 1-mile radius intersects a designated state-approved Wellhead Protection Area or source water protection zone, an additional 20 points are added to the Targets category.
- Resources Factor: An automatic 5 points added if water from the aquifer is used for irrigation, livestock, or commercial food prep.
5. Mathematical Path to the $\ge 28.50$ Threshold
To understand how rapidly a site exceeds the NPL listing threshold:
$$\text{Assume:}$$
$$\text{LR} = 550\text{ (Observed Release confirmed)}$$
$$\text{WC} = 32\text{ (Conservative baseline for heavy metals)}$$
$$\text{Targets (T)} = 150\text{ (Level I school well + private wells within 1 mile)}$$
$$S_{gw} = \frac{550 \times 32 \times 150}{82,500} = \frac{2,640,000}{82,500} = 32.0$$
Under the HRS root-mean-square site scoring rule:
$$S_{\text{site}} = \sqrt{\frac{S_{gw}^2 + S_{sw}^2 + S_{s}^2 + S_{a}^2}{4}}$$
Even if the other three pathways (surface water $S_{sw}$, soil exposure $S_s$, air $S_a$) are treated as zero, a Ground Water Pathway score of $S_{gw} = 57.0$ yields:
$$S_{\text{site}} = \sqrt{\frac{57.0^2 + 0 + 0 + 0}{4}} = \frac{57.0}{2} = \mathbf{28.50}$$
Any documented Level I contamination in a public or municipal drinking well within 1 mile that serves several hundred individuals readily drives $S_{gw}$ above 60 to 80 points, pushing the total composite site score well into the 35.00 to 50.00+ range, legally establishing federal Superfund eligibility.
-------------------------
Under the EPA Hazard Ranking System (HRS, 40 C.F.R. Part 300, App. A), karst conduit dynamics create a unique regulatory duality: subterranean conduit flow can be evaluated under Section 3.0 (Ground Water Migration Pathway), Section 4.1 (Surface Water Overland/Flood Migration Component), or via the specialized Ground Water to Surface Water Component (Section 4.2).
Because groundwater in mature karst limestone discharges rapidly through resurgences, springs, and cave outlets into streams and rivers, the HRS treats these conduits differently depending on whether the contaminated fluid remains in the phreatic zone or emerges into daylight.
1. Structural Comparison: Ground Water vs. Surface Water Pathways
| Scoring Component | Ground Water Migration Pathway (Section 3.0) | Surface Water: Overland / Flood Component (Section 4.1) | Surface Water: Ground Water to Surface Water (Section 4.2) |
| Physical Medium Evaluated | Saturated bedrock voids, dissolution conduits, fractures, and deep phreatic zones. | Runoff from landfill slopes, gullies, ditches, and direct overland sheet flow into streams. | Subterranean karst conduits discharging directly into a surface water body via a spring, seeps, or cave mouth. |
| Target Distance Limit (TDL) | 4.0-mile radius from the sources at the site. | 15.0 downstream miles along the receiving stream network from the probable point of entry (PPE). | 15.0 downstream miles measured from the point of spring/conduit resurgence. |
| Likelihood of Release (LR) Max Score | 550 points (Observed Release) or up to 500 points (Potential to Release). | 550 points (Observed Release) or up to 500 points (Potential to Release). | 550 points (Derived from either an observed release to groundwater or directly to the spring resurgence). |
| Primary Target Metrics | Drinking water well populations (municipal, school, domestic) and Wellhead Protection Areas. | Surface drinking water intakes, human food chain fisheries, sensitive environments, and wetlands. | Surface drinking water intakes, fisheries, and aquatic environments located within 15 miles downstream of the karst spring. |
2. How Karst Discharges are Evaluated in Each Pathway
A. Ground Water Migration Pathway (Section 3.0)
- Observed Release Criteria: Requires sampling an underground well or subterranean conduit. If a compliance well or private drinking well completed in the limestone aquifer detects leachate contaminants (e.g., mercury, chlorinated solvents) at $\ge 3\times$ background (or above the sample quantitation limit if background is non-detect), an Observed Release (550 points) is established.
- Potential to Release (Karst Vulnerability): If no well is contaminated yet, karst terrain receives the absolute maximum weighting in the Hydraulic Conductivity factor category ($K \ge 10^{-2}\text{ cm/s}$ = 10,000 points within the matrix), driving the containment and likelihood of release factor close to the maximum.
- Targets Focus: Exclusively counts drinking water wells completed within the 4-mile TDL. Wells with Level I actual contamination (exceeding MCLs) are multiplied by 10, heavily weighting institutional facilities (such as schools) or municipal wellfields.
B. Surface Water: Overland/Flood Migration (Section 4.1)
- Point of Origin: Evaluates leachate seeps breaking out on landfill berms, failed retention basin overflows, and stormwater letdown ditches draining into a stream tributary.
- Runoff & Containment: Landfills lacking engineered liners, run-on diversion berms, or daily cover receive maximum containment penalty values (assigned 10 points).
- Target Multipliers: Targets are not limited to drinking water; they evaluate three separate target categories:
- Drinking Water Intakes: Surface water intakes within the 15-mile TDL.
- Human Food Chain: Commercial or recreational fisheries (e.g., trout waters where fish are harvested for consumption), weighted by annual catch volume in pounds.
- Sensitive Environments: Stream segments supporting state or federally listed endangered/threatened aquatic species (e.g., freshwater mussels, native trout), designated wetlands acreage, or high-quality coldwater streams.
C. The Karst Bridge: Ground Water to Surface Water Component (Section 4.2)
When an unlined landfill discharges leachate into underground karst conduits that subsequently resurge at a valley spring feeding a river tributary, the EPA does not limit evaluation to drinking wells. Under Section 4.2:
- The Spring Resurgence is the PPE: The karst spring is officially designated as the Probable Point of Entry (PPE) into the surface water pathway.
- Observed Release to Surface Water: Demonstrating that dye or contaminants traveled from the landfill to the spring resurgence establishes an Observed Release (550 points) to surface water without needing to prove direct overland runoff.
- Downstream 15-Mile TDL: The 15-mile Target Distance Limit begins at the spring mouth and extends downstream, evaluating all downstream water intakes, fisheries, and sensitive trout habitats.
3. Key Scoring Differences in Practice
Landfill Source
│
├──► [Subterranean Karst Conduit] ──► PCHS / Municipal Wells
│ • Scored under: Ground Water Pathway (§ 3.0)
│ • TDL: 4-mile radial zone
│ • High Points: Drinking water population (Level I x 10)
│
└──► [Spring Resurgence / Seeps] ──► Tributary & Greenbrier River
• Scored under: Surface Water Pathway (§ 4.1 or § 4.2)
• TDL: 15 downstream miles
• High Points: Trout fishery, wetlands, endangered aquatic species
- Population vs. Environmental Receptors:
- Ground Water scoring is almost entirely driven by the number of people consuming water from wells. A small rural population with no municipal intakes can struggle to generate high Target points unless an actual Level I impact hits a high-density school or cluster of homes.
- Surface Water scoring can exceed the 28.50 threshold even in sparsely populated areas because fisheries and sensitive aquatic ecosystems carry independent, heavy point allocations. Bioaccumulative substances like mercury carry an automatic human food chain factor of 50,000, meaning any documented fishery impact dramatically inflates the score.
- Dilution & Flow Attenuation:
- Ground Water does not apply stream dilution factors; well targets are evaluated strictly by distance bands and level of contamination.
- Surface Water adjusts targets based on the stream flow rate (dilution weight). Discharges entering small headwater tributaries or low-flow karst resurgences receive higher scoring weights (dilution weight of 1.0) than discharges entering large rivers with high dilution capacity.
- Compound Site Scoring Advantage:
- Because site scores use the root-mean-square formula, demonstrating that karst conduits feed both drinking water wells (Ground Water Pathway) and resurgence streams supporting fisheries/sensitive habitats (Surface Water Pathway) enables evaluators to score both pathways concurrently, routinely driving the final composite score far above the 28.50 threshold.
Immediate Documentation Focus for Karst Scoring
- Map All Resurgence Points: Identify every karst spring, cave discharge, and seep along the 1-mile corridor leading to the nearest surface tributary.
- Determine Fishery & Endangered Species Classifications: Document whether the receiving tributary or downstream river reaches are designated by state wildlife agencies as native trout waters or critical habitats for protected freshwater mollusks.
- Coordinate Co-Located Sampling: When collecting water quality data from monitoring wells, take concurrent samples at downgradient resurgence springs to provide the evidentiary link required under HRS Section 4.2.
------------------------------------
Under the EPA Hazard Ranking System (HRS, 40 C.F.R. Part 300, App. A, Section 4.1.3), the Human Food Chain (HFC) Threat evaluates the risk posed when hazardous substances released into surface waters accumulate in aquatic organisms harvested for human consumption.
When bioaccumulative substances like mercury are discharged into coldwater trout streams, the mathematical design of the HRS allows this single threat to generate high scores even in rural areas with relatively low human population density.
1. The Human Food Chain Threat Equation
The threat score ($S_{hfc}$) is the normalized product of three factor categories:
$$S_{hfc} = \frac{\text{Likelihood of Release (LR)} \times \text{Waste Characteristics (WC)} \times \text{Targets (T)}}{82,500}$$
(The maximum score for $S_{hfc}$ is capped at 100 points, which is then summed with the Drinking Water Threat and Environmental Threat to determine the total Surface Water Pathway score.)
2. Likelihood of Release (LR)
- Observed Release (550 Points): If water or sediment samples from the stream or a discharging karst resurgence demonstrate mercury concentrations significantly above background ($\ge 3\times$ background or above the detection limit), an Observed Release is established, locking LR at its statutory maximum of 550.
- Potential to Release (0 to 500 Points): If an observed release has not yet been documented, scores are derived from landfill containment, rainfall runoff, and distance to surface water.
3. Waste Characteristics (WC): The Bioaccumulation Multiplier
In standard drinking water scoring, Waste Characteristics is capped at a factor value of 100. However, in the Human Food Chain Threat, the formula incorporates the Bioaccumulation Potential Factor Value (BPFV), increasing the maximum possible WC score from 100 up to 1,000:
[Toxicity Factor] x [Persistence Factor] x [Hazardous Waste Quantity]
│
▼ (Capped at 10^8)
[Product] x [Bioaccumulation Potential Factor Value (BPFV = 50,000 for Mercury)]
│
▼ (Capped at 10^12)
Assigned Waste Characteristics Factor Value (Up to 1,000 via HRS Table 2-7)
- Toxicity Factor: Total Mercury carries the maximum toxicity value of 10,000 in the Superfund Chemical Data Matrix (SCDM).
- Persistence Factor: As a non-degradable inorganic metal, mercury receives a persistence rating of 1.0 (rivers/streams).
- Bioaccumulation Potential Factor Value (BPFV): Because methylmercury biomagnifies rapidly through aquatic food webs (trophic transfer from macroinvertebrates to benthic forage to predatory trout), SCDM assigns freshwater mercury the maximum BPFV of 50,000.
- Result: Multiplying by a BPFV of 50,000 elevates the Waste Characteristics score to 320 to 1,000 points (compared to 10 to 32 points for non-bioaccumulative pollutants).
4. Targets (T): Evaluating Trout Fisheries
A fishery is established under HRS rules if: (1) an aquatic food-chain organism (e.g., brook, brown, or rainbow trout) is present, and (2) there is any documented attempt by humans to catch and consume them (recreational angling, local consumption, paths/line remnants along banks).
The Targets score is the sum of two components: Food Chain Individual (FCI) and Food Chain Population (FCP).
$$\text{Targets (T)} = \text{Food Chain Individual (FCI)} + \text{Food Chain Population (FCP)}$$
A. Food Chain Individual (FCI)
This factor evaluates the single individual at greatest risk (e.g., an angler consuming catch from the stream) and is frequently the primary driver of the score:
- Level I Actual Contamination (50 Points): Triggered if edible fish tissue samples (trout fillets) demonstrate mercury concentrations that meet or exceed FDA/EPA health-based action levels (e.g., $0.3\text{ mg/kg}$ or specific cancer/systemic screening benchmarks).
- Level II Actual Contamination (45 Points): Triggered if an observed release of a substance with a high BPFV ($\ge 500$, such as mercury's 50,000) is documented in the water or sediment within the fishery reach, even if no fish tissue samples have been analyzed.
- Potential Contamination (0.01 to 20 Points): If the fishery lies within the 15-mile Target Distance Limit (TDL) downstream but outside the documented observed release zone, assigned based on stream dilution flow weights.
B. Food Chain Population (FCP)
Population is evaluated by converting the annual commercial and recreational harvest of fish (in pounds per year) into human consumer equivalents, adjusted by the stream dilution weight:
$$\text{Pounds of Fish Harvested per Year} \div 16.5\text{ lbs/year (EPA reference adult consumption)} = \text{Population Equivalent}$$
| Stream Flow Category | Mean Annual Streamflow (Q) | Dilution Weight (Di) |
| Headwater / Karst Resurgence Stream | $< 10\text{ cfs}$ | 1.0 (No dilution reduction) |
| Small River (e.g., Upper Greenbrier reaches) | $10\text{ to }100\text{ cfs}$ | 0.1 |
| Moderate River | $100\text{ to }1,000\text{ cfs}$ | 0.01 |
- If the fishery has Level I Actual Contamination, the population equivalent is multiplied by $10\times$ and is not diluted ($D_i = 1.0$).
- If the fishery has Level II Actual Contamination, the population equivalent is weighted at $1\times$ without dilution reduction.
5. Mathematical Scoring Example: Karst Headwater Trout Stream
Consider an unlined landfill discharging mercury into a karst resurgence that feeds a coldwater headwater trout stream ($Q < 10\text{ cfs}$):
- Likelihood of Release (LR): Observed release of mercury documented at stream confluence = 550.
- Waste Characteristics (WC): Mercury toxicity (10,000) $\times$ Persistence (1.0) $\times$ BPFV (50,000) with baseline hazardous waste quantity = 320 (via Table 2-7).
- Targets (T):
- Level II Fishery documented (water/sediment mercury detect + BPFV of 50,000): $\text{FCI} = \mathbf{45}$.
- Modest recreational trout harvest (500 lbs/year $\approx 30$ people equivalents): $\text{FCP} \approx \mathbf{1.0}$.
- Total Targets = $45 + 1.0 = \mathbf{46.0}$.
$$\text{Threat Score } S_{hfc} = \frac{550 \times 320 \times 46.0}{82,500} = \frac{8,096,000}{82,500} = \mathbf{98.13}$$
Under the HRS root-mean-square site scoring equation ($S_{\text{site}} = \sqrt{\frac{S_{sw}^2 + \dots}{4}}$), a surface water pathway score of $98.13$ yields:
$$S_{\text{site}} = \frac{98.13}{2} = \mathbf{49.07}$$
Because 49.07 is substantially higher than the 28.50 Superfund cutoff, the presence of bioaccumulative mercury in a localized trout fishery is sufficient on its own to make a facility eligible for National Priorities List listing, even without counting drinking water wells.
-----------------
In West Virginia, fish consumption advisories are developed jointly through an interagency protocol involving the West Virginia Department of Health and Human Resources (WVDHHR / Bureau for Public Health), the West Virginia Department of Environmental Protection (WV DEP), and the Division of Natural Resources (WVDNR).
Advisories are based on empirical fish tissue sampling (fillet composites) and risk-based toxicological models designed to limit chronic human exposure to methylmercury, a bioaccumulative neurotoxin.
1. Risk-Based Action Levels & Meal Consumption Tiers
West Virginia utilizes EPA risk assessment methodology (EPA Reference Dose for methylmercury: $\text{RfD} = 1 \times 10^{-4}\text{ mg/kg/day}$) assuming a standard 8-ounce (227-gram) meal for an average adult. Fish tissue mercury concentrations (measured as total mercury in milligrams per kilogram, $\text{mg/kg}$, or parts per million, $\text{ppm}$, wet weight) trigger specific consumption restriction tiers:
| Tissue Mercury Concentration Range (mg/kg / ppm, wet weight) | Advisory Consumption Restriction | Regulatory & Health Exposure Interpretation |
| $< 0.12\ \text{mg/kg}$ | Unrestricted / Unlimited | Deemed safe for frequent regular consumption (typical for stocked hatchery trout). |
| $0.12\ \text{to } 0.25\ \text{mg/kg}$ | 1 Meal per Week | Statewide baseline advisory limit for general forage and panfish species. |
| $0.26\ \text{to } 0.50\ \text{mg/kg}$ | 2 Meals per Month | Applied to mid- and high-level predatory species (e.g., bass, walleye). |
| $0.51\ \text{to } 1.00\ \text{mg/kg}$ | 1 Meal per Month | Strict advisory level applied to long-lived apex predators or waters with specific point-source mercury contamination. |
| $1.01\ \text{to } 2.00\ \text{mg/kg}$ | 6 Meals per Year | Severe restriction applied to heavily impacted waterbodies. |
| $> 2.00\ \text{mg/kg}$ | DO NOT EAT (No Consumption) | Acute biological accumulation threshold; complete ban on sportfish consumption. |
- Sensitive Subpopulations: Women of childbearing age, pregnant or nursing mothers, and children under age 15 are advised to follow restrictions that are one full tier more conservative than the general public (or completely avoid predatory fish from waters carrying $\ge 1\text{ meal/month}$ restrictions).
2. Statewide Default Advisories vs. Site-Specific Waterway Listings
Because airborne deposition and historical mining/industrial runoff cause low-level background contamination across Appalachia, West Virginia enforces a blanket statewide baseline advisory that automatically applies to all state waters not subject to a more stringent site-specific rule:
[Statewide Baseline Advisory]
├──► Rainbow Trout: Unlimited / Safe for regular diet (short hatchery lifecycle)
├──► Rock Bass, Suckers, Channel Catfish (<17"), All Other Panfish: 1 Meal / Week
├──► Black Bass (Largemouth, Smallmouth, Spotted), Walleye, Sauger, Flathead Catfish: 2 Meals / Month
└──► White Bass: 1 Meal / Month
- Site-Specific Advisory Triggers: When WV DEP fish tissue monitoring identifies localized waterbodies where tissue burdens exceed statewide averages (such as specific reaches of the Shenandoah River, Kanawha River, or impoundments like Summersville Lake), a site-specific advisory is issued restricting consumption to 1 meal/month or "Do Not Eat".
3. WV DEP Water Quality Criteria & Section 303(d) Impairment Listing
Separate from the WVDHHR public health consumption advice, the WV DEP applies statutory water quality criteria to determine whether a waterbody must be placed on the federal Clean Water Act Section 303(d) List of Impaired Waters:
- Fish Tissue Body Burden Standard (47 C.S.R. § 2, Table 1, Section 8.18):
- West Virginia’s statutory numeric water quality standard establishes that the total organism body burden of mercury in any aquatic species must not exceed $0.5\ \text{mg/kg}$ ($0.5\ \text{ppm}$).
- (Comparison note: EPA's national recommended methylmercury tissue criterion under CWA § 304(a) is $0.3\ \text{mg/kg}$; West Virginia retains the $0.5\ \text{mg/kg}$ threshold in its legislative rule.)
- Surface Water Concentration Standards:
- $0.012\ \mu\text{g/L}$ for chronic aquatic life protection (Category B).
- $0.05\ \mu\text{g/L}$ for human health and public water supply intakes (Category A).
- 303(d) Listing & TMDL Trigger: If fish tissue composite samples from a stream segment exhibit mean mercury levels $\ge 0.5\ \text{mg/kg}$ (or if a "Do Not Eat" / severe advisory is enacted), the WV DEP classifies that segment as impaired for aquatic life and human consumption uses, requiring development of a Total Maximum Daily Load (TMDL).
4. Technical Sampling Protocols for Fish Tissue Assessment
To ensure legal defensibility in permit challenges and Superfund evaluations, WV DEP and WVDNR follow standard EPA field and lab criteria:
- Composite Sampling: Each sample consists of a composite of at least 3 to 5 legal-size fish of the same species, with the smallest fish measuring at least 75% of the length of the largest.
- Tissue Preparation: Edible scaled, skin-on fillets (for scaled species) or skinless fillets (for catfish/eels) are homogenized and analyzed to reflect the actual food-chain exposure pathway of recreational anglers.
- Analytical Method: Tested for total mercury using Cold Vapor Atomic Absorption (EPA Method 245.6 / 7470A) or low-level Cold Vapor Atomic Fluorescence Spectrometry (EPA Method 1631E). In fish tissue, $>90\%$ of total mercury is assumed to be in the toxic methylmercury form.
