Our report brings together utility and contaminant records from EWG, EPA system history, and regional hardness estimates. The report identifies its sources and dates, and explains where data is missing.
Exceeding an EWG health guideline is different from exceeding an enforceable legal limit. Neither a ZIP-level report nor a regional hardness estimate establishes the current quality of water inside your home.
