What it means: Asbestos enters drinking water primarily from the deterioration of asbestos-cement (AC) pipes, which were widely used in US water distribution systems between the 1930s and 1980s. Some naturally occurring asbestos deposits can also contribute. Corrosive water (low pH, soft water) accelerates pipe degradation and fiber release.
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.
Limit: 7 million fibers per liter (MFL) — fibers longer than 10 micrometers
About this contaminantAbout this data
EPA counts the rules a system was in violation of, not the individual violations; one rule can carry several in the same period. Unresolved means still in violation at EPA's latest data refresh. Measured contaminant levels are not part of this record; each system publishes them in its annual Consumer Confidence Report.
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.
