The Commerce Street Plume, EPA ID 110071100071, remains an active site on the National Priorities List. Environmental investigations focus on a groundwater plume containing chlorinated solvents, primarily trichloroethene, which originated from past industrial activities. The primary exposure pathways involve the inhalation of vapors migrating from contaminated groundwater into residential structures and the potential ingestion of untreated groundwater. Long-term exposure to these hazardous substances is linked to increased risks of liver damage, immune system dysfunction, and certain cancers. Regulatory oversight by the EPA ensures ongoing monitoring, but the critical hazard score indicates significant local risk. To mitigate exposure, residents should implement three defensive measures. First, install a high-quality vapor intrusion mitigation system if your property sits above the plume area. Second, utilize activated carbon water filtration systems for all tap water to remove volatile organic compounds. Third, request a soil gas test from environmental professionals to verify indoor air safety. Regularly check the EPA’s Superfund site profile for the Commerce Street Plume to receive updates on cleanup progress and remedial actions. Maintaining awareness of local land-use restrictions is essential for residents within a five-mile radius of the nine identified regional hazard sites.
