Nottingham, New Hampshire, zip code 03290, carries a critical environmental hazard designation due to a high concentration of surrounding federal cleanup operations. While zero sites sit within a radius of five miles, six active environmental hazards exist within ten miles. The nearest facility is the 28 Main Street Area, located 6.6 miles from the zip code center. The Environmental Protection Agency currently lists the 28 Main Street Area and surrounding locations, including Harding Metals Inc and Tibbetts Road, under active National Priorities List status. This indicates that formal site investigation, remediation, and containment protocols are presently underway but remain incomplete.

The primary environmental threats in this sector involve unspecified hazardous substances. Exposure to such industrial waste mixtures typically occurs through groundwater leaching, soil vapor intrusion, or airborne particulate transport. Chronic exposure to these volatile compounds and heavy metals can disrupt endocrine functions, degrade respiratory health, and cause severe neurological or developmental impairments in residents. Because the precise chemical profile remains publicly unclassified under the general hazardous designation, the risk of undetected residential exposure remains a highly serious concern.

Given the active status of these multiple locations, residents should implement rigorous protective measures. Households utilizing private wells must conduct comprehensive annual water testing specifically screening for harmful volatile organic compounds and toxic heavy metals. Furthermore, residents should install certified reverse osmosis filtration systems to mitigate potential groundwater contamination before any human consumption. Finally, individuals planting edible gardens must strictly utilize raised beds filled with imported, certified soil to bypass historical contamination.
