The Coating Sciences, Inc. (Former) site, EPA ID 110071100576, remains on the active National Priorities List. This facility is one of five major hazardous sites within a five-mile radius and one of twenty-nine within ten miles. Primary contaminants are categorized as unspecified hazardous substances. Exposure pathways include vapor intrusion into buildings, groundwater contamination, and direct soil contact. Long-term exposure to industrial pollutants increases the risk of respiratory issues, neurological damage, and certain cancers. The EPA oversees cleanup efforts to mitigate plume migration and ensure site containment. Residents should follow three defensive measures to reduce risk. First, install a certified high-efficiency particulate air filtration system to manage indoor air quality. Second, test basement levels for volatile organic compounds if your property sits atop a known groundwater plume. Third, avoid gardening in native soil without first conducting a professional heavy metal and chemical analysis. Monitoring local EPA reports for the Kaman Aerospace and Jacobs Manufacturing sites is also recommended, as these nearby facilities contribute to the cumulative regional hazard score. Regular updates on remediation progress are available through the EPA database for the Hartford area.
