PFAS in Nevada drinking water

59 Nevada public water systems tested under UCMR5. 10 detected at least one PFAS compound; 49 detected none at the reporting thresholds. Values are the highest single result per compound, in ng/L (parts per trillion). The federal limit for PFOA and PFOS is 4 ng/L.

Systems with no PFAS detected

49 tested systems reported no PFAS above the laboratory reporting limits. Each has its own page with its sampling detail.

A detection at the system level does not tell you what reaches one specific tap: levels vary by entry point, treatment train and plumbing. A certified lab test of your own tap settles it. Testing and treatment options
