What this means

These figures are county-level and come from EPA’s sampling of public water systems. They describe the worst result found in the county, not what comes out of any particular tap — that depends on which system serves the address, and on the plumbing in the building. A private well is not covered by this programme at all.

This is a county-level reading from federal monitoring. What comes out of your own tap depends on your system — and on your home.
