NSF International, a group that tests and certifies water filtration systems, lists 77 products that can reduce PFAS to below the Environmental Protection Agency’s health advisory level. First, the federal government does not regulate PFAS and there is no agreed-upon safe level for drinking water. California has about 3,000 water providers, some of which purchase water from wholesalers that operate their own groundwater wells. Some California water utilities have shut down contaminated wells, put them on “emergency-only” status or processed their water through treatment plants. If you’re interested in testing, California drinking water officials recommend that you contact a laboratory that’s accredited for PFAS testing.
