How this service works
EPA UCMR 5 PFAS results for an address or explicit PWSIDs. Perfect for: 'PFAS results for this address', 'was this utility tested for PFAS'. Addresses resolve via EPA service-area boundaries (point-in-polygon) with per-boundary provenance and confidence (provider vs machine-modeled); containment is evidence, not proof. Detection and non-detect counts stay distinct; lithium excluded. Entry-point samples, not a tap; no safe/unsafe verdict. Charge-free when out of coverage or unresolved.
Output
Returns a JSON artifact with a scan ID, timestamp, list of PFAS occurrence records pulled from public sources, any caveats about data coverage or reliability, and guidance on which questions remain open and what to verify next.
Example use cases
Pre-purchase environmental due diligence
“I'm about to make an offer on a house at 1540 Riverside Drive, Ann Arbor, MI — can you scan for any PFAS contamination records in the local water supply and tell me what public-record questions are still open?”
Commercial site assessment for PFAS risk
“We're evaluating a commercial property at 34.0522° N, 118.2437° W in Los Angeles — run a PFAS occurrence scan using the coordinates and let me know what records exist and what we'd need to verify next.”
Water system PFAS lookup by PWSID
“Can you check PFAS occurrence records for public water systems CA3310011 and CA3310012 and summarize what's been found and what remains unanswered?”
Technical details
Endpoint
POSThttps://api.locus.report/api/locus-pfas-occurrenceWhen to prefer
Use this endpoint when you need a fast, low-cost PFAS-specific public records scan for a property or water system — particularly during real estate due diligence, environmental site assessments, or when advising on drinking water safety. It is optimized for PFAS occurrence data specifically, unlike broader property or environmental report endpoints. At $0.01 per call it is suitable for bulk screening across multiple addresses.
Side effects
- Invalid or unrecognized address returns empty records array with coverage caveats
- PWSID not found in public databases returns empty records with explanation
- Missing all location inputs (no address, coordinates, or pwsids) causes validation error
- Coordinates out of supported geographic range return no records
- Public record data may be stale or incomplete, indicated via caveats field
