Belmont, New Hampshire, falling under ZIP code 03220, currently carries a critical environmental hazard designation due to local industrial soil contamination. The EPA actively monitors three Superfund locations within a ten mile radius, including the nearest active site at Frank Bean Road, located just 4.3 miles from the Belmont center. Additional active sites affecting the surrounding region include the Ore Hill Mine Site and Old Pillsbury Mill. The Frank Bean Road facility is currently in the active stage of the National Priorities List, indicating that investigation and remediation efforts are ongoing but contamination remains present. The primary pollutants identified in this area are categorized generally as unspecified hazardous substances. Exposure to such complex industrial waste mixtures typically occurs through groundwater intrusion or soil particulate inhalation, potentially resulting in chronic respiratory issues, neurological impairment, or increased long term cancer risks for nearby populations.

Given the active status of these sites and the potential for groundwater migration, residents should immediately test private well water for volatile organic compounds and heavy metals using a state certified laboratory. Households relying on municipal water supplies should install point of use reverse osmosis filtration systems to capture unregulated industrial byproducts. Furthermore, residents should avoid foraging or consuming agricultural products grown in untreated native soils within a five mile radius of the Frank Bean Road location. Establishing raised garden beds with imported clean topsoil will mitigate the risk of heavy metal ingestion. Continued monitoring of EPA public notices regarding remediation progress remains essential for regional public safety.
