The New Durham, New Hampshire, zip code 03855 area currently carries a critical environmental hazard designation due to concentrated proximity to active federal remediation sites. The primary environmental threat originates from the Merrymeeting Road Drum Site, located approximately three miles from the residential center. The Environmental Protection Agency classifies the primary contaminants at this location as unspecified hazardous substances. Exposure to legacy industrial chemicals and volatile organic compounds typically found in uncharacterized drum disposal sites can cause immediate respiratory irritation, neurological issues, and long term organ damage through prolonged ingestion or inhalation. The Merrymeeting Road Drum Site remains an active federal National Priorities List cleanup project under EPA oversight, meaning critical environmental stabilization and remediation efforts are ongoing but not yet complete. The local environmental threat profile is further compounded by three additional active hazardous waste sites located within a ten mile radius of the community, specifically the Cardinal Landfill, the former Collins and Aikman Plant, and Miltonia Management Incorporated.

Because of the active regulatory status of these overlapping regional contamination zones, residents must implement immediate environmental safety precautions. Individuals utilizing private residential wells should immediately test their drinking water supplies for volatile organic compounds and heavy metals. Households should install certified point of use reverse osmosis filtration systems for all potable water sources to effectively intercept potential groundwater leaching from these sites. Finally, to prevent secondary exposure pathways, residents should strictly avoid foraging or consuming any agricultural products grown in untreated local soil until all federal remediation officially concludes.
