Environmental hazards, flood and water records in Concord, MA

Public environmental, infrastructure and surveillance records inside Concord'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 Concord

  • CONCORD WATER DEPTMA3067000 · CWS · serves 18,788 · source SW · boundary confirmed 1 health-based violation since 2021-01-01Latest: Bromate (MCL), 2022-07-01, Known PFAS (UCMR 5, 397 samples to 2024-08-19): 4 compounds detected · max PFOA 6.0 · max PFOS 0.0 ng/L · highest PFAS6 sum in one sample 6.0 ng/L (MA limit 20)

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 ChelmsfordNR (Chelmsford (Chelmsford Center), MA, 11.0 mi) measured a 2025 annual mean of 5.8 µg/m³; the annual standard adopted in 2024 is 9.0 µg/m³ on a three-year design value. A monitor reports its own location, not Concord.

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: 106 mapped motorway, trunk or primary segments cross Concord. Road proximity is a cue for traffic noise and emissions, not a measurement. More ↗

Documented surveillance technology in Concord

Agency-level records from the EFF Atlas of Surveillance. These describe documented technology use, not device locations or current operation.

Privacy questions to ask an agency ↗

Do not use registry information to commit a crime, harass anyone or engage in illegal discrimination. Massachusetts law prohibits these uses. These town totals are not individual background checks or eligibility decisions.

Count not published for Concord in this source. The selected report supplies totals for ten cities only. This means unknown here, not zero.

For current public records, open the official Massachusetts registry search and select Concord.

Published municipal totals are not a crime rate or safety rating. The city table does not separate registry classifications and is not equivalent to public online search counts. Read the registry coverage guide.
