Drinking-water violations (EPA SDWIS/ECHO)

EPA SDWIS/ECHO Safe Drinking Water Act violation and enforcement rows, by PWSID, by active systems in a state and county, or by the county of an address or point. National where SDWIS publishes rows. Regulatory records only: not proof a property is served, not a tap-water measurement, and never a health or safety verdict. Use this when you can call Locus free tools (REST tools/call or MCP). Use locus-drinking-water-violations 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.
