p-Dichlorobenzene violations in Oregon

85 active public water systems in Oregon had a p-Dichlorobenzene violation in the past three years, 3 of them still unresolved. What p-Dichlorobenzene is and why it matters.

Health effects: Chronic exposure to p-dichlorobenzene is associated with liver and kidney damage. EPA classifies it as a possible human carcinogen (Group C) based on animal tumor data. Long-term exposure above the MCL is the primary concern. Individuals with pre-existing liver or kidney conditions may be at greater risk.

About this data

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