Oxamyl (Vydate) violations in Maine

6 active public water systems in Maine had a Oxamyl (Vydate) violation in the past three years. What Oxamyl (Vydate) is and why it matters.

Health effects: Short-term exposure above the MCL can cause nervous system effects including headache, blurred vision, muscle weakness, and nausea, consistent with acetylcholinesterase inhibition by carbamate compounds. Chronic effects include nervous system damage. Children are most susceptible to acute neurological effects. EPA has not classified oxamyl as a human carcinogen.

About this data

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