ATSDR Map of PFAS Sites

ATSDR's official map identifies locations where ATSDR is involved in investigating PFAS in the environment, while its downloadable layers supply site identity, engagement or study type, state, a supporting site page where populated, and point geometry. It therefore supplies an official environmental-investigation-history screen at or near a parcel, but not contamination confirmation, remediation, lifecycle status, concentration, case identity, or parcel identity. Use only entries whose environmental-investigation context and site identity are corroborated and whose coordinates are valid; health-study participation alone does not qualify, and null or apparently malformed coordinates must not be used unverified for parcel proximity.
