Hanover, New Hampshire, encompassing the 03755 zip code, currently holds a high environmental hazard designation due to regional industrial contamination. While there are no Superfund sites within a five-mile radius, three distinct facilities operate within ten miles, elevating the ecological risk profile. The nearest regulated facility is Bakers Store, located 7.2 miles away.

Bakers Store is currently designated with an active National Priorities List status. This active regulatory phase indicates that the Environmental Protection Agency is actively managing the site, conducting ongoing remedial investigations, or executing active environmental cleanup measures to contain migration. The primary pollutants registered at this location are unspecified hazardous substances. Exposure to these unclassified industrial chemicals typically occurs through groundwater migration or soil vapor intrusion. Depending on the exact chemical composition, residents exposed to such volatile substances may experience respiratory irritation, dermatological conditions, or long-term systemic toxicities impacting the neurological or hepatic systems. Contamination from nearby active sites like the Ely Copper Mine and Bradford Veneer and Panel Co Inc compounds these regional water and soil vulnerabilities.

Given the active status of these adjacent facilities and the uncertainty of the specific chemical plumes, Hanover residents should implement immediate protective measures. Households utilizing private wells should commission comprehensive annual water testing specifically screening for volatile organic compounds and heavy metals. Additionally, residents should install certified point-of-use reverse osmosis water filtration systems to mitigate potential groundwater contamination. Finally, individuals should periodically review regional Environmental Protection Agency groundwater monitoring reports to adapt their household safety measures as site investigations evolve.
