The East Main Street Disposal Area, EPA ID 110009328664, is currently listed as an active site on the National Priorities List. Regulatory oversight confirms that unspecified hazardous substances remain on the property, creating potential exposure pathways through groundwater ingestion, dust inhalation, and soil vapor intrusion. Long-term exposure to industrial contaminants often leads to respiratory issues, skin irritation, or chronic organ stress. There are 12 hazardous sites within 10 miles, indicating a dense concentration of legacy industrial pollution in the New Haven area. To mitigate personal risk, residents should implement three specific defensive measures. First, install a high-efficiency particulate air filtration system to reduce the inhalation of contaminated dust. Second, use certified carbon-activated water filters for all drinking and cooking needs to block potential groundwater seepage. Third, establish a strict no-shoes policy inside the home to prevent tracking contaminated soil into living spaces. Ongoing monitoring by the EPA is required to determine the full extent of the chemical plume. Residents must review the official EPA site records periodically to track progress on cleanup milestones and changes in containment status. This critical hazard score reflects the proximity and active status of the disposal area.
