What is in your water?
Explore contamination data for public water systems across the United States. Search your area to see what has been detected in your local supply.
The fine print, kept simple
This map pulls contamination data from public U.S. water testing records, including the EPA public API and UCMR sampling. The values shown are the reported figures for public water systems, not our interpretation, and are not a test of the water at your individual tap. Coverage depends on the EPA source datasets. This is not a substitute for your local water utility's annual Consumer Confidence Report (CCR).
Matched Protection
Your water, matched to the right filter pack.
The Nexxus System paired with your area-matched filter pack targets what has been detected in your local supply: Heavy Metals Defense, VOC Guard Max, or Lead Barrier Pro. Add the Delta Plan to keep it handled, with filters auto-replenished on schedule so your protection never lapses.
