The Linemaster Switch Corp-Treatment Plant is an active site on the National Priorities List. According to EPA records for site 110049849107, the location is undergoing long-term cleanup to manage unspecified hazardous substances. Exposure pathways include drinking contaminated groundwater or breathing vapors that rise through the soil into residential structures. Health risks involve potential damage to internal organs and an increased risk of cancer from chronic exposure. Residents should take three specific defensive measures. First, test private wells for hazardous chemicals and heavy metals every year through a certified laboratory. Second, use a certified multi-stage water filtration system for all household tap water to remove potential toxins. Third, seal any cracks in your basement floor and ensure high-quality indoor air circulation to prevent vapor intrusion from contaminated soil. There are 14 hazardous sites within 10 miles, including the Mace Polymer Fire and Northeast Utilities locations, which increases the cumulative environmental burden on the community. Monitoring federal updates on these sites is essential for maintaining a safe living environment and reducing toxic exposure.
