Environmental hazards, flood and water records in Medford, MA
Public environmental, infrastructure and surveillance records inside Medford's municipal boundary, plus the regional air, drinking-water, flood, radon and Superfund context that does not stop at the town line. Each item links to its original record. Nothing here is a risk score.

Counts are records inside the municipal boundary, not unique facilities and not a ranking. Sources carry different dates (June 2024 for MassDEP waste layers, TRI 2024, OpenStreetMap Sept 2026). Community-mapped items are unverified. No record does not prove absence.

Beyond the town line
Air pollution follows wind and stack height, water comes from wherever the supplier draws it, and a Superfund plume ignores municipal boundaries. These items are searched from the town's center across state lines.

Drinking water, radon, air quality, flood
Community water systems serving Medford
- MEDFORD WATER DEPT. (MWRA) 2 health-based violations since 2021-01-01
Boundaries are estimates and do not verify a household connection. Sample results are at treatment or entry points, not at a tap. Drinking-water questions to ask ↗ · PFAS explained ↗
Radon, particle pollution, flood
Radon: Middlesex County is EPA Zone 1, the highest predicted indoor radon potential (county average above 4 pCi/L). EPA says the zone map must not be used to decide whether to test; homes in every zone have measured high levels. Testing guidance ↗
Fine particles (PM2.5): nearest regulatory monitor BOSTON KENMORE SQ (Boston, MA, 5.3 mi) measured a 2025 annual mean of 6.3 µg/m³ (incomplete year); the annual standard adopted in 2024 is 9.0 µg/m³ on a three-year design value. A monitor reports its own location, not Medford.
Flood: FEMA flood zones are point-specific. Use the map to query the National Flood Hazard Layer live at an address. Flood questions to ask ↗
Major roads: 273 mapped motorway, trunk or primary segments cross Medford. Road proximity is a cue for traffic noise and emissions, not a measurement. More ↗
