West Virginia's approximately 1.8 million residents live in one of the most geologically complex and environmentally contested states in the country. Drinking water comes primarily from surface water – rivers and reservoirs fed by Appalachian watersheds – supplemented by groundwater in some areas. The Ohio River, which forms the state's western border, supplies water to communities from Wheeling to Huntington. The Kanawha, Elk, and Monongahela rivers serve interior communities. Charleston, the capital, draws from the Elk River. The West Virginia Bureau for Public Health, within the Department of Health and Human Resources, regulates public water systems.
West Virginia holds a unique and unfortunate distinction in the national PFAS story: it is where the contamination was first exposed on a massive scale. The DuPont Washington Works plant in Parkersburg – later operated by Chemours – discharged PFOA (also known as C8) into the Ohio River and surrounding environment for decades, beginning in the 1950s. This is the contamination that became the subject of the landmark legal case, the book "Exposure" by Robert Bilott, and the 2019 film "Dark Waters."
The scope of the contamination was staggering. DuPont used C8 in the manufacture of Teflon at the Parkersburg facility and dumped waste containing the compound into unlined landfills, directly into the Ohio River, and through air emissions that settled on surrounding land. Internal DuPont documents, revealed through litigation, showed that the company knew about the health risks of C8 as early as the 1960s but continued operations and concealed findings.
The resulting legal battle, initiated by farmer Earl Tennant and later expanded by attorney Robert Bilott into a class-action lawsuit, led to the C8 Science Panel – an independent epidemiological study funded by DuPont under a court settlement. The panel studied nearly 70,000 people in the Mid-Ohio Valley and found probable links between C8 exposure and six diseases: kidney cancer, testicular cancer, thyroid disease, ulcerative colitis, high cholesterol, and pregnancy-induced hypertension. This was the first large-scale epidemiological study to establish connections between PFAS exposure and specific health outcomes, and its findings have shaped PFAS regulation worldwide.
DuPont eventually settled thousands of personal injury claims for a combined $671 million in 2017, and the company spun off its chemical operations to Chemours in 2015. The Washington Works plant is still operational, and monitoring of the Ohio River and surrounding groundwater continues.
The contamination affected six water districts in the Mid-Ohio Valley, serving approximately 70,000 people. The Lubeck, Mason County, and Little Hocking water districts in both West Virginia and Ohio were among the most affected. While treatment systems have been installed to reduce C8 levels in drinking water, the legacy of exposure – decades of contamination before anyone was informed – cannot be undone.
The DuPont C8 case dominates West Virginia's PFAS narrative, but the state faces broader water quality challenges. Coal mining – both active and legacy – has left a lasting mark on watersheds throughout the state. Acid mine drainage, where water percolating through exposed coal seams and mine waste picks up sulfuric acid and heavy metals, has degraded thousands of stream miles. The West Virginia DEP has documented over 4,000 miles of streams impaired by acid mine drainage.
The Ohio River, which supplies drinking water to hundreds of thousands of West Virginians, carries the cumulative load of industrial discharge, agricultural runoff, and municipal wastewater from communities across multiple states. The Ohio River Valley Water Sanitation Commission (ORSANCO) coordinates monitoring, but the river's role as both industrial corridor and drinking water source creates inherent tension.
The 2014 Elk River chemical spill – when crude MCHM leaked from a Freedom Industries storage tank into the Elk River upstream of Charleston's water intake – left 300,000 people without usable water for days and exposed how vulnerable the state's water systems are to industrial accidents. The spill prompted legislative action and increased scrutiny of chemical storage near waterways, but infrastructure vulnerabilities persist.
West Virginia's PFAS story is unlike any other state's because it is the origin story. The DuPont C8 case established the legal, scientific, and regulatory framework that every subsequent PFAS action has built upon. The C8 Science Panel's findings are cited in virtually every state and federal PFAS regulatory proceeding. The legal strategy developed by Bilott – using discovery to expose corporate knowledge of harm – became the template for PFAS litigation nationwide.
In terms of current regulation, West Virginia has been less aggressive than states that experienced PFAS contamination later and had the benefit of established science. The state has not adopted PFAS-specific drinking water MCLs, relying on federal standards. This is partly a reflection of the state's political dynamics – the chemical industry remains a significant economic force – and partly a function of limited state regulatory resources.
The EPA's UCMR5 data for West Virginia shows detections consistent with the state's industrial and military history, though the Mid-Ohio Valley around Parkersburg remains the area of greatest concern. Remediation at the Washington Works facility is ongoing, and the transition from DuPont to Chemours has added corporate complexity to the cleanup process.
West Virginia residents face a combination of PFAS, mining legacy, and industrial contamination that makes water quality awareness particularly important.
1. Check your water quality using our free tool. If you are in the Mid-Ohio Valley – particularly in Wood, Pleasants, or Mason counties – PFAS data is especially relevant. 2. If you rely on Ohio River water, understand that your supply carries contamination from sources across multiple states. Point-of-use filtration can reduce exposure to both PFAS and other industrial contaminants. Our water filter guide covers which systems are certified for the compounds that matter in this region. 3. For communities affected by coal mining – particularly in the southern coalfields – testing for heavy metals and acid mine drainage indicators is important alongside PFAS. A detailed water report can help you understand the full picture for your address. 4. Private well owners in rural areas should test independently. Many rural West Virginia communities are not served by public water systems, and private wells in areas with mining or industrial history may carry contaminants that have never been measured.
West Virginia's water quality history is a chronicle of extraction and its consequences. The state's coal industry, which powered America's industrialization, operated for over a century with minimal environmental regulation. By the time the Clean Water Act (1972) and the Surface Mining Control and Reclamation Act (1977) established federal oversight, decades of unregulated mining had already contaminated thousands of stream miles.
The chemical industry arrived in the Kanawha Valley in the early 20th century, earning Charleston the nickname "Chemical Valley." DuPont, Union Carbide, Monsanto, and other major chemical manufacturers operated along the Kanawha and Ohio rivers, producing a contamination legacy that persists in sediment, groundwater, and the river systems themselves.
DuPont's Washington Works plant began manufacturing Teflon in Parkersburg in 1951. C8 was used as a processing aid, and waste containing the compound was disposed of through methods that would be unthinkable today – dumped into unlined pits, pumped into the Ohio River, and released through air emissions. The contamination was not unknown to DuPont; internal studies in the 1960s and 1970s documented that C8 accumulated in the blood of workers and animals, but the information was not shared with regulators or the public.
When farmer Earl Tennant began losing cattle in the 1990s – animals drinking from a creek that received runoff from a DuPont landfill – his complaint eventually reached Robert Bilott, an attorney at the Cincinnati firm Taft Stettinius & Hollister. Bilott's two-decade legal campaign against DuPont uncovered internal documents showing corporate knowledge of C8 toxicity, led to the C8 Science Panel study, and resulted in the largest PFAS-related legal settlement in history at the time.
The C8 Science Panel, which operated from 2005 to 2012, conducted one of the most extensive community health studies ever performed. The probable disease links it established – kidney cancer, testicular cancer, thyroid disease, ulcerative colitis, high cholesterol, and pregnancy-induced hypertension – remain the foundation of PFAS health risk assessment and have been cited by the EPA, state regulators, and international health agencies.
The 2014 Elk River spill added another chapter. The Freedom Industries facility that leaked MCHM into the river sat just upstream of Charleston's water intake and had not been inspected in years. The resulting water ban affected 300,000 people across nine counties and exposed gaps in West Virginia's chemical storage oversight. State legislation passed in response has improved but not eliminated the vulnerability.
Today, West Virginia's water quality is shaped by these overlapping legacies – coal mining, chemical manufacturing, and the nation's first major PFAS disaster. For residents of the Mid-Ohio Valley, the DuPont contamination is not history; it is a lived experience with ongoing health monitoring and legal proceedings.
