Drinking-Water Data Editor
EPA SDWIS public water systems, contaminant violations, and compliance records
Greta Vetrov leads how WaterSafety reads and presents the EPA Safe Drinking Water Information System (SDWIS). The role decides which SDWIS fields and reporting vintage each water-system, city, state, and contaminant page uses — population served, source type, and the health-based versus procedural violation split — and documents the methodology and triages corrections. Violation histories, compliance records, and contaminant figures are drafted with AI assistance and editorially reviewed against the underlying EPA SDWIS releases before publication.
