Asbestos violations in California

5 active public water systems in California had a Asbestos violation in the past three years. What Asbestos is and why it matters.

Health effects: Long-term ingestion of elevated asbestos levels is associated with an increased risk of benign intestinal polyps (mesothelioma from ingestion remains uncertain in the scientific literature). Inhalation risk from drinking water is considered minimal. EPA classifies asbestos as a Group B1 probable human carcinogen based on inhalation data.

About this data

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