Chromium violations in Mississippi

7 active public water systems in Mississippi had a Chromium violation in the past three years. What Chromium is and why it matters.

Health effects: Hexavalent chromium is associated with increased cancer risk through ingestion in animal studies and is classified by EPA as a probable human carcinogen (Group B1) for inhalation, with growing evidence for oral carcinogenicity. Chronic exposure to total chromium causes liver and kidney damage, allergic dermatitis, and gastrointestinal irritation. Individuals with pre-existing liver or kidney conditions face greater risk.

About this data

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