How To Read These Water Records
A plain-language summary of what the official records on this page show — and what they do not show.
Official records for Medway Water Department include both EPA UCMR 5 PFAS sampling records and health-based violation records identified in EPA's SDWIS database. The PFAS sampling records are monitoring data — a detection indicates the compound was measured, not that a regulatory standard has been exceeded. The health-based violation records are separate entries in the SDWIS compliance database. Water Utility Report summarizes official records and source data. It does not determine whether water is safe to drink.
What the records show
- EPA UCMR 5 sampling records are on file for Medway Water Department. UCMR 5 is a monitoring program that measures compounds not yet regulated — the presence of a record indicates these compounds were sampled.
- Health-based violation records are listed, identified as such in EPA's SDWIS database. These records indicate the utility exceeded a regulated Maximum Contaminant Level (MCL) at some point.
- Utility-level records reflect system-wide monitoring at the point of distribution, not conditions at individual taps. Household plumbing, service lines, and fixtures may differ.
