1,1-Dichloroethylene violations in New Jersey
77 active public water systems in New Jersey had a 1,1-Dichloroethylene violation in the past three years, 5 of them still unresolved. What 1,1-Dichloroethylene is and why it matters.
Health effects: Chronic exposure to 1,1-dichloroethylene is associated with liver and kidney damage. EPA classifies it as a possible human carcinogen (Group C) based on animal data. Acute high-level exposure can cause central nervous system depression. 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 1,1-Dichloroethylene, including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not 1,1-Dichloroethylene 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 New Jersey 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.
