The 03042 zip code area of Epping, New Hampshire, carries a critical environmental hazard designation due to the close proximity of multiple hazardous waste facilities. Located just 3.0 miles from residential zones, the Keefe Environmental Services facility is the primary environmental threat to the community. The Environmental Protection Agency lists the prevailing pollutants at this location as unspecified hazardous substances. Exposure to such volatile industrial chemicals, whether through groundwater migration or soil contamination, presents severe health risks to the human body, potentially causing respiratory irritation, neurological impairment, and elevated long-term carcinogenic vulnerability. Keefe Environmental Services currently maintains an active status on the National Priorities List. This active regulatory designation indicates that federal remediation and monitoring efforts remain ongoing, as the location has not yet achieved the strict safety thresholds required for delisting. The surrounding region is notably concentrated with industrial hazards, featuring seven total monitoring sites within a ten-mile radius, including the Mottolo Pig Farm, Regis Tannery, and Blue Ribbon Drycleaners.

Given the active status of these environmental remediation zones, residents must implement protective measures to mitigate local exposure. Households utilizing private wells must install advanced reverse osmosis water filtration systems immediately to intercept migrating subterranean contaminants. Residents should also test indoor air quality annually for volatile organic compounds to detect potential vapor intrusion originating from shifting groundwater plumes. Furthermore, individuals planting residential gardens should utilize raised beds with imported soil to bypass lingering ground-level toxicity from nearby legacy industrial operations.
