EPA Sole Source Aquifer designation context

EPA Sole Source Aquifer designations at an address or point, with region, link, and Federal Register citation. EPA reviews federally funded projects under SDWA 1424(e), not private permits. A clean negative needs a validated current snapshot; stale data is explicit. Includes Guam, Hawaii, and Puerto Rico. Use this when you can call Locus free tools (REST tools/call or MCP). Use locus-sole-source-aquifer instead when your client can only call paid x402 routes; it returns the same records. Direct flat-body route for this one free resource; no API key, payment, or catalog wrapper. Return only the cited bounded evidence described here; this route never produces a paid brief or full report.
