Chester, New Hampshire, encompassing the 03036 ZIP code, currently carries a critical environmental hazard designation due to significant proximity to multiple active Superfund locations. The area sits within a ten-mile radius of seven federally monitored hazardous waste operations, with the most immediate threat originating from the Mottolo Pig Farm site, located approximately 4.4 miles away. The Mottolo Pig Farm is listed on the Environmental Protection Agency’s National Priorities List under an active cleanup status, meaning remediation efforts and environmental monitoring remain ongoing. The primary threat profile involves unspecified hazardous substances historically disposed of at the facility. These volatile chemicals present profound risks through potential groundwater migration and soil vapor intrusion. Exposure to these synthetic contaminants can compromise human health, resulting in chronic respiratory issues, neurological impairment, and increased risks of specific cancers depending on the duration and pathway of ingestion or inhalation. The regional threat is compounded by the active Auburn Road Landfill and Regis Tannery sites situated just beyond the five-mile radius.

Given the active remediation status of these surrounding environmental hazards, Chester residents should implement immediate household safeguards. Homeowners relying on private wells must schedule annual comprehensive water testing specifically targeting hazardous volatile organic compounds and heavy metals to ensure drinking water remains safe. Residents should also install certified reverse osmosis filtration systems for all potable water sources utilized within the household. Finally, individuals planting residential gardens must utilize raised beds filled with imported, certified-clean topsoil to definitively eliminate any potential exposure risks linked to legacy soil contamination.
