2,4,5-TP (Silvex) violations in Pennsylvania

248 active public water systems in Pennsylvania had a 2,4,5-TP (Silvex) violation in the past three years, 7 of them in the latest quarter of EPA's data. What 2,4,5-TP (Silvex) is and why it matters.

Health effects: Chronic exposure to Silvex is associated with liver damage. EPA classifies it as a possible human carcinogen (Group C). The dioxin contamination historically associated with its production added to concern about its carcinogenicity, though the MCL applies to Silvex itself. Long-term exposure above the MCL is the primary concern.

About this data

A system is counted once if any of its violations in the past three years involved 2,4,5-TP (Silvex), including monitoring and reporting lapses. Rules violated and status in the table are for the whole system, not 2,4,5-TP (Silvex) 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 Pennsylvania 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.
