Dinoseb violations in Rhode Island

8 active public water systems in Rhode Island had a Dinoseb violation in the past three years. What Dinoseb is and why it matters.

Health effects: Dinoseb uncouples oxidative phosphorylation, disrupting cellular energy production. Chronic exposure causes reproductive toxicity: impaired sperm production in males and developmental harm, including birth defects, in developing fetuses. EPA has not established a formal carcinogenicity classification. Reproductive-age adults and pregnant women face the greatest risk.

About this data

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