The 232 East 1st Avenue site, identified by EPA ID 110071100942, maintains an active status on the National Priorities List. This classification indicates that high concentrations of Volatile Organic Compounds require ongoing federal remediation to prevent public harm. Primary exposure pathways include groundwater ingestion and vapor intrusion, where chemical gases migrate from contaminated soil into residential foundations. Chronic exposure to these VOCs is linked to respiratory distress, neurological damage, and increased cancer risks. Nearby facilities like Rahway River VOC Contamination and General Electric Co. further saturate the local environment with toxic runoff. To mitigate these specific risks, residents should implement three defensive measures. First, install high-efficiency particulate air filters with activated carbon to trap airborne chemical vapors. Second, conduct professional laboratory testing on all private well water to ensure it meets safety standards for volatile pollutants. Third, consult with environmental engineers regarding the installation of sub-slab depressurization systems or vapor barriers if your property sits atop known plumes. Federal oversight continues as the EPA monitors 122 sites within a ten-mile radius of Westfield. Constant vigilance is necessary because soil and water movement can transport these hazardous compounds beyond the immediate boundaries of designated Superfund zones. Maintaining structural integrity prevents gas.
