The Leed-Himmel Industries site, EPA ID 110001729979, is currently an active site on the National Priorities List. Cleanup status involves ongoing monitoring of unspecified hazardous substances released during past operations. Exposure pathways for residents include the inhalation of contaminated dust, ingestion of chemicals via groundwater migration, and dermal contact with legacy pollutants in the soil. Health risks from these exposures include respiratory distress, neurological impacts, and long-term systemic toxicity. The density of twenty-eight sites within ten miles, including Pero Property and the Newhall Street Field, increases the cumulative toxic load on the community. To defend against these risks, install HEPA-certified air purifiers to remove industrial particulates from indoor air. Use professional-grade water filtration systems to mitigate potential groundwater contaminants. Establish a shoes-off policy indoors to prevent tracking contaminated exterior soil into living spaces. Detailed site records are maintained in the EPA Superfund database for public review.
