MCLs, MRDLs, and treatment technique rules are all health-based drinking water standards.”Find your water system

From EPA's Safe Drinking Water Information System (SDWIS), through EPA ECHO's drinking water system download. Health-based violations from EPA Envirofacts, downloaded Nov. 2, 2026. EPA's file dated Oct. 23, 2026. EPA: “All compliance and enforcement data displayed on ECHO are current as of the last official quarterly refresh of the source data system, SDWIS, which may lag by three to six months.” These are records of violations, not a test of your tap water today: your water system's annual Consumer Confidence Report has its test results. Names and values are shown as EPA writes them. EPA ECHO drinking water search.
