The National Priorities List currently classifies 35 MLK Blvd (EPA ID 110067349630) as an active site requiring federal oversight. The primary contaminant is radium, a radioactive element that decays into radon gas. Exposure pathways include the inhalation of indoor air where radon has accumulated and the ingestion of contaminated groundwater. Long-term radium exposure is linked to increased risks of bone cancer and kidney damage. Regulatory efforts focus on soil excavation and the installation of radon mitigation systems to reduce indoor air risks. Residents must adopt three specific defensive measures. First, install a certified radon mitigation system in the lowest level of the home to vent radioactive gases. Second, avoid using private well water for drinking or bathing unless it has been tested specifically for radionuclides. Third, maintain a permanent vegetation cover over bare soil to prevent the inhalation of contaminated dust particles during dry or windy periods. Current remediation status indicates ongoing monitoring is necessary due to the density of nearby hazardous sites, including the Montclair/West Orange Radium Site located only 1.4 miles away. These concentrated industrial hazards require strict adherence to local environmental advisories.
