The 03105 zip code area in Manchester, New Hampshire, operates under a critical environmental hazard designation due to concentrated industrial and military contamination. Residents live within 1.9 miles of the New Boston Air Force Station, an active environmental threat managed by the Environmental Protection Agency. Furthermore, the surrounding ten-mile radius contains an alarming concentration of eleven contaminated locations, including the Savage Municipal Water Supply and the Grugnale Waste Disposal Site.

The primary threat originating from the New Boston Air Force Station involves unspecified hazardous substances. While the exact chemical composition remains broadly classified by the military, such pollutants typically include volatile organic compounds, heavy metals, and perfluoroalkyl substances. Chronic exposure to these legacy contaminants through groundwater migration or soil vapor intrusion can disrupt endocrine systems, impair neurological development, and elevate long-term cancer risks among the local population.

This installation maintains an active status on the National Priorities List, indicating that the EPA is engaged in ongoing, long-term remedial evaluation and active cleanup operations, meaning full environmental containment is not yet complete.

Given the proximity and active status of these sites, residents should implement rigorous protective measures immediately. Households utilizing private groundwater wells must secure comprehensive laboratory testing specifically targeting volatile organic compounds and heavy metals. Residents should immediately install certified reverse osmosis filtration systems at all primary drinking water point-of-use taps to intercept potential chemical migration. Finally, individuals participating in local agriculture or gardening should strictly utilize raised beds with imported, certified-clean topsoil to prevent dermal exposure or ingestion of subsurface soil contaminants.
