Aldicarb Sulfoxide violations in Wisconsin

2 active public water systems in Wisconsin had a Aldicarb Sulfoxide violation in the past three years. What Aldicarb Sulfoxide is and why it matters.

Health effects: Like its parent compound aldicarb, aldicarb sulfoxide inhibits acetylcholinesterase, disrupting nerve signal transmission. Acute exposure causes cholinergic symptoms: headache, blurred vision, nausea, muscle weakness, and in severe cases, respiratory distress. Children are most vulnerable to acute neurological effects from carbamate exposure.

About this data

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

The Wisconsin 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.
