How to read this table
Legal limit
EPA MCLs and action levels are compliance standards. They are not the same as stricter health goals.
Health guideline
Health-guideline context can be more conservative and should be labeled clearly.
Home-level certainty
Public utility data does not prove the exact contaminant level at one faucet.
Trust and source notes
Built from public water data, then translated for the home
BaseWater's contaminant pages use public utility reports, EPA-linked SDWIS or UCMR context, EWG health-guideline context, row-level official checks for high-stakes claims, and BaseWater source-quality labels. BaseWater pages separate legal compliance from stricter health-guideline context. They are not a medical diagnosis or a tap-level lab result for any individual home.
