Water in West Virginia.

Parkersburg-area PFOA contamination from DuPont's Washington Works was the original U.S. PFAS public-health crisis, documented in The Devil We Know and Dark Waters. The 2014 Elk River chemical spill left 300,000 Charlestonians without safe tap water for over a week.

Industry profile

Where the contamination comes from.

Every state has a different industrial fingerprint. The industries below are the dominant historical and active contamination sources in West Virginia's drinking water systems.

DuPont Washington Works (Parkersburg) PFOA contamination is the foundational U.S. PFAS public-health crisis. Kanawha River chemical corridor (Elk River 2014) drives chronic concerns. Coal mining and processing legacy across eastern WV.

Who's most exposed

Risk isn't evenly distributed.

Demographic risk read

Mid-Ohio Valley residents (Parkersburg / Vienna / Lubeck) face the most-documented PFAS exposure in the U.S. Coal-region residents face heavy-metal exposure.

Private wells

~25% on private wells, with significant mining-related contamination in coal regions.

Climate threats

What's coming for West Virginia's water.

Appalachian flooding intensity (2016 June flood) overwhelms small-system infrastructure. Coalfield post-mining hydrology destabilization. Kanawha River chemical-corridor flooding risk.

What to ask your utility

Five questions for your next Consumer Confidence Report.

Your utility is required to send you a Consumer Confidence Report annually. Most are dense and procedural. These are the questions worth following up on for West Virginia specifically.

  1. 1

    If I'm in Mid-Ohio Valley, am I in the C8 Health Project zone (eligible for ongoing monitoring)?

  2. 2

    Has my Charleston-area utility had any post-Elk-River chemical-spill protocol activations?

  3. 3

    If I'm in coal country, has my well been tested for selenium and sulfate?

Most state regulators allow public records requests for the underlying lab reports behind your CCR — your utility should be able to provide them on request.

Filter recommendation for West Virginia

For PFAS in Mid-Ohio Valley: NSF/ANSI P473 or RO. DuPont-funded POE filter systems available for confirmed impacted households.

We don't recommend brands — the NSF/ANSI certification number matters more than the name on the box.
