The Mrs. Bubbles site, identified by EPA ID 110071100080, maintains an active status on the National Priorities List. Regulatory oversight is currently focused on identifying the full scope of unspecified hazardous substances present at the facility. Exposure pathways primarily include the ingestion of contaminated groundwater and the inhalation of volatile organic compounds that may migrate through soil gas. High-risk exposure to such hazardous substances often leads to long-term respiratory issues, skin irritation, or more severe systemic organ damage depending on the chemical concentration. Nearby sites like the former Dow Air Force Base Fire Training Area and local dry cleaning facilities further complicate the regional chemical profile. To protect your household, you should immediately install a high-grade carbon water filtration system to capture potential runoff contaminants. Ensure your home has a functioning vapor barrier or radon mitigation system to prevent soil gases from entering the basement. Regularly test your private well water for a broad spectrum of industrial pollutants to monitor for shifts in water quality. These defensive measures reduce the risk of direct contact with the legacy pollutants migrating from the eight documented sites within a ten-mile radius of Holden.
