The former Coating Sciences, Inc. site, EPA ID 110071100576, is currently classified as an active site on the National Priorities List. With 27 hazardous locations within a ten-mile radius, the primary exposure pathways include groundwater contamination and soil vapor intrusion. Hazardous substances at these sites pose long-term health risks such as respiratory issues, skin irritation, and potential neurological effects depending on specific chemical concentrations. Residents should regularly check the EPA’s Superfund Enterprise Management System for updates on cleanup progress and environmental monitoring reports. To minimize exposure, residents must follow three defensive measures. First, install a high-quality water filtration system certified to remove volatile organic compounds. Second, maintain a shoes-off policy inside the home to prevent tracking contaminated soil into living spaces. Third, ensure proper basement ventilation or install a radon-style mitigation system to reduce the risk of inhaling chemical vapors that seep through the foundation. These actions provide a layer of protection against unspecified hazardous substances moving from the Coating Sciences facility or the East Hartford Municipal Landfill into residential zones. Monitoring local air quality alerts is also recommended during periods of high wind or construction activity at these industrial sites.
