BHC-Gamma (Lindane) violations in Oklahoma

104 active public water systems in Oklahoma had a BHC-Gamma (Lindane) violation in the past three years. What BHC-Gamma (Lindane) is and why it matters.

Health effects: Lindane affects the central nervous system; acute high-dose exposure causes seizures, muscle spasms, and liver damage. Chronic exposure is associated with liver and kidney damage and immune system effects. EPA classifies lindane as a probable human carcinogen (Group B2). Children are particularly vulnerable to neurological effects.

About this data

A system is counted once if any of its violations in the past three years involved BHC-Gamma (Lindane), including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not BHC-Gamma (Lindane) 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 Oklahoma 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.
