The Angelillo Property (EPA ID: 110009334906) remains on the National Priorities List as an active cleanup site. Regulatory oversight confirms the presence of hazardous substances that present significant exposure pathways through groundwater ingestion and soil contact. Nearby residents are particularly vulnerable to the Cheshire Ground Water Contamination plume located less than a mile away. Long-term exposure to these unspecified toxins can cause chronic respiratory issues, neurological damage, or increased cancer risks depending on the chemical concentration. The EPA monitors these locations to mitigate the spread of pollutants into the local aquifer. To protect your household, you must take specific defensive measures. First, install a high-efficiency particulate air filtration system to reduce indoor dust and airborne particles. Second, utilize certified carbon-block water filters for all drinking and cooking water to intercept potential groundwater contaminants. Third, maintain a strict shoes-off policy inside the home to prevent the tracking of contaminated exterior soil into living spaces. Regularly check the EPA official site for real-time updates on the 59 sites within a ten-mile radius. Strict adherence to these protocols is necessary given the critical 10.0 hazard rating for the 06411 area.
