Styrene violations in Tennessee

11 active public water systems in Tennessee had a Styrene violation in the past three years. What Styrene is and why it matters.

Health effects: Chronic exposure to styrene is associated with liver, kidney, and nervous system effects. EPA classifies it as a possible human carcinogen (Group C) based on limited animal evidence. Short-term exposure can cause irritation of the eyes, nose, and throat. Long-term exposure above the MCL is the primary concern for public water system violations.

About this data

A system is counted once if any of its violations in the past three years involved Styrene, including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not Styrene 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 Tennessee 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.
