Overview
Returns EPA Sole Source Aquifer designation containment and Federal Register citations for an address, for agents. Returns the same records as locus_sole_source_aquifer. Use this when your client can only call paid x402 routes. Use locus_sole_source_aquifer instead when you can call Locus free tools (REST tools/call or MCP).

"boundary": {
"estimatedGroundToleranceMeters": 20.28,
"geometryCrs": "EPSG:4326",
"geometrySimplified": true,
"nearSimplifiedBoundary": false,
"note": "The source boundary was simplified for bounded lookup. The tolerance is stated in Web Mercator metres; its approximate ground-distance equivalent varies with latitude.",

"toleranceMercatorMeters": 25
},
"caveats": [
"The designation is not a contamination finding, says nothing about current water quality, does not itself restrict a private owner, and is not an ordinary private-construction permit decision.",
"Most of the country is outside a Sole Source Aquifer designation. Being outside one does not mean groundwater is unimportant or unprotected.",
"The active snapshot uses simplified mapped boundaries. A point close to a boundary needs confirmation from EPA; this lookup is not a survey or legal boundary determination."
],
"designations": [],
"kind": "epa_sole_source_aquifer",
"meaning": "EPA's Sole Source Aquifer designation means the aquifer supplies at least 50% of the drinking water for its service area and no economically feasible alternative is available; under SDWA -1424(e), EPA reviews federally funded projects in the designated area for potential to contaminate the aquifer.",
"message": "The point is outside every designation boundary in the active EPA snapshot. Most of the country is outside a Sole Source Aquifer designation. Being outside one does not mean groundwater is unimportant or unprotected.",
"multipleDesignations": false,
"note": "Awareness/diagnostic only. Full briefs are x402-paid. Agents can discover live free tools at https://api.locus.report/tools/list and paid tools, prices, and manifests at https://api.locus.report/.well-known/ai-tool/index.json.",
