Environmental Protection Agency (EPA) — Water Quality
Data Used: Three EPA data sources are combined for the Water Quality filter:
- EPA ATTAINS — Impaired surface waters assessed under Clean Water Act Section 303(d). 500-foot buffer applied around impaired rivers, streams, lakes, ponds, estuaries, and coastal waters.
- EPA Superfund/NPL — National Priorities List contaminated site boundaries. 1-mile buffer applied around site boundaries to account for contaminant plume migration.
- EPA SDWIS — Safe Drinking Water Information System. Community water system service area boundaries for systems with active health-based violations (MCL/MRDL/treatment technique). No additional buffer — the service area polygon represents the affected area.
If any source flags a location, it is excluded from the safe overlay. Unassessed waters are assumed clean per EPA guidance.
