The DOD/USN SB/AREA A LANDFILL #2 is currently an active site on the National Priorities List under EPA ID 110070605270. This facility is part of the U.S. Naval Submarine Base New London complex. Primary contaminants include unspecified hazardous substances that migrate through groundwater and soil vapor pathways. Exposure occurs through the ingestion of contaminated well water or inhalation of vapors entering basements. Long-term health risks include potential organ damage, developmental issues, or increased cancer risk depending on the specific chemicals present. There are nine hazardous sites within five miles, including New London Textile Print and the Price Driscoll Site, creating a cumulative exposure risk. Residents must take defensive measures to limit contact. First, install a high-grade carbon filtration system for all household water to remove chemical particulates. Second, conduct professional soil vapor intrusion testing in basements to ensure air quality is safe from migrating plumes. Third, avoid gardening in native soil; use raised beds with imported, certified clean soil to prevent the ingestion of industrial toxins. Regular monitoring of EPA cleanup progress reports for the Naval Submarine Base is necessary to stay informed about remediation efforts.
