Hundreds of wells are contaminated across California. Find out where uses colored markers to highlight the wells where unsafe chemicals were detected, where no chemicals were detected in addition to where a wellness advisory has been issued for the well. If you lot hover over a good on the map you lot tin sentiment the levels of PFOS in addition to PFOA detected inwards the good (if any). The EPA has established wellness advisory levels at lxx parts per trillion for PFOS in addition to PFOA.

This way that they don’t suspension downwards in addition to their levels tin thus accumulate over time. Exposure to these chemicals tin Pb to adverse human wellness effects.



The Environmental Working Group has created a nationwide interactive map of PFC contamination inwards drinking water.The PFC Contamination Map uses information from the the Environmental Protection Agency to demo the degree of PFC's found inwards H2O supplies at the county level.

You tin read to a greater extent than virtually the dangers of PFC's in addition to the PFC Contamination Map inwards this EWG article. Many of the highest levels of PFC contamination inwards groundwater convey been found at armed forces sites (often from burn downwards fighting foams containing PFC's). The EWG has besides created a listing of the 100 USA Military Sites With the Worst PFAS Contamination.
