The LEED-HIMMEL INDUSTRIES site, identified by EPA ID 110001729979, is currently on the active National Priorities List. This status indicates that the site poses a significant threat to human health or the environment requiring federal intervention. Contaminants move through various exposure pathways, primarily through groundwater migration and soil vapor intrusion. Because the primary contaminants are listed as unspecified hazardous substances, health risks include potential respiratory issues, skin irritation, and long-term organ damage. The EPA continues to monitor the site to determine the full extent of the plume. Residents should take three immediate defensive measures to reduce risk. First, install a certified high-efficiency particulate air filtration system in the home to capture airborne particulates. Second, refrain from any gardening or excavation activities that disturb the local soil within a two-mile radius of the site. Third, utilize only municipal water sources for drinking and cooking while avoiding the use of private wells which may be contaminated by groundwater runoff. Ongoing regulatory oversight aims to contain the spread of these substances, but the high density of surrounding industrial sites complicates remediation efforts in the Waterbury area.
