The 1109th Aviation Classification & Repair Depot, identified by EPA ID 110001408432, remains on the National Priorities List with an active status. Regulatory oversight focuses on investigating unspecified hazardous substances that may migrate from the facility. Exposure pathways primarily include the infiltration of chemicals into local aquifers and the suspension of contaminated particulates in the air. Health risks associated with aviation-related industrial sites often involve heavy metals or volatile organic compounds, which can cause respiratory issues, organ damage, or increased cancer risks over prolonged periods. Within a ten-mile radius, ten total sites, including the DOD/USN SB Landfill and Tilcon CT Asphalt, create a cumulative environmental burden. To mitigate personal risk, residents should implement three defensive measures. First, install high-quality carbon filtration systems on all drinking water taps. Second, maintain a shoes-off policy indoors to prevent tracking contaminated soil into living spaces. Third, subscribe to EPA site updates to monitor remediation progress and public health advisories. Consistent monitoring of local air quality and soil testing for private properties is recommended to ensure the safety of the residential environment in West Mystic.
