How to read this map
- Red — a possible hazard to the water. Sand pits, bogs, landfills, the incinerator, PFAS sites. Digging and dumping over an aquifer removes the natural sand filter that cleans rain before it becomes drinking water.
- Purple squares — companies in the case files. The operators, owners, and buyers behind the sites. Tap one to see everything it runs.
- Blue — the water itself. Treatment plants, wells, and schools: where the aquifer becomes someone's tap water.
- The blue wash is the aquifer. That shaded area is the actual EPA-designated Plymouth-Carver Sole Source Aquifer boundary (55 FR 32137, 1990) — the underground water supply everything on this map sits on, over, or beside.
- A pulsing ring means an active court order, state review, or enforcement action right now.
Individuals are not shown on this public map — companies and sites are. Every pin and every string is a claim drawn from public records — court filings, agency records, deeds, and press reporting — not a legal conclusion. The full sourcing lives in the case files.
Pins are geocoded from public street addresses; a few fall back to a road or town center where an exact parcel could not be resolved. Aquifer boundary: EPA sole source aquifer designation via the MassGIS public data layer. Town lines: MassGIS.
