The Chestel, Inc. site (EPA ID: 110009271894) is currently active on the National Priorities List. Regulatory records indicate the presence of unspecified hazardous substances that require long-term remedial action. Primary exposure pathways include groundwater migration and soil vapor intrusion, which occur when chemicals evaporate and enter buildings through foundations. Health risks associated with these contaminants typically include respiratory issues, skin irritation, and increased long-term cancer risks if ingestion or inhalation occurs over extended periods. There are eight hazardous sites within ten miles of Essex, including the Haddam Municipal Landfill just over two miles away. To protect your household, implement three defensive measures. First, install a high-quality water filtration system certified to remove volatile organic compounds. Second, conduct regular vapor intrusion testing in your basement to ensure soil gases are not accumulating indoors. Third, maintain a shoes-off policy inside the home to prevent tracking potentially contaminated outdoor soil into living areas. These steps mitigate the risk of chronic exposure while federal cleanup efforts remain ongoing.
