Groundwater Rule (GWR) violations in Kansas

26 active public water systems in Kansas had a Groundwater Rule (GWR) violation in the past three years, 11 of them in the latest quarter of EPA's data. What Groundwater Rule (GWR) is and why it matters.

Health effects: Protects against enteric viruses, which can contaminate groundwater via cracked well casings, failing septic systems, or animal waste. Viruses persist longer in groundwater than in surface water. Hepatitis A and norovirus are the primary pathogens of concern.

About this data

A system is counted once if any of its violations in the past three years involved Groundwater Rule (GWR), including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not Groundwater Rule (GWR) alone.

Source: the U.S. EPA's Enforcement and Compliance History Online system (ECHO), which publishes the federal Safe Drinking Water Information System. EPA's terms and values are shown as published. The Kansas records are from EPA's data refresh of Oct 7, 2026; EPA refreshes this data quarterly, and states report to EPA with a lag of three to six months, so the newest violations may not appear yet.
