* exceeds the final federal MCL for that compound. Detections of compounds whose limits EPA proposed to rescind in May 2026 are shown for information.

Systems with no PFAS detected

68 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
