How Idaho’s score works
We pull every active community water system in Idaho from the EPA’s Safe Drinking Water Information System, then find those with a health-based violation in the last five years. The score is the share of the state’s water-system population served by systems without such a violation. City-level detail — utility, lead levels, and specific contaminants — is coming next.
Full methodology · Compliance snapshot, not a live reading. A system meeting federal standards can still carry risk (e.g. lead from home service lines). Not medical advice.
