Harrisville, Rhode Island, carries a critical environmental hazard designation due to a severe density of industrial contamination areas. Within a five mile radius of the 02830 zip code, twelve active environmental hazards are currently tracked, escalating to twenty six sites within a ten mile radius. The nearest major facility is the Mendon Street Automotive (Former) site, located 4.7 miles away. This location maintains an active status on the EPA National Priorities List, indicating that federal remediation efforts, site assessments, and long term environmental monitoring are currently underway. Several other proximate active hazards compound regional risks, including Boliden Metech Inc, Western Sand and Gravel, and Landfill and Resource Recovery, Inc.

The EPA classifies the primary pollutants at the Mendon Street Automotive (Former) site as unspecified hazardous substances. While the exact chemical compounds remain broadly categorized in initial federal dockets, exposure to legacy automotive byproducts typically involves volatile organic compounds and heavy metals. These contaminants frequently migrate through local groundwater aquifers or soil vapor. Prolonged exposure to such pollutants can compromise local well water quality and precipitate neurological, respiratory, or developmental health issues.

Given the high concentration of surrounding active Superfund sites, residents must implement rigorous protective measures immediately. Homeowners relying on private wells should commission annual comprehensive water testing specifically targeting volatile organic compounds and heavy metals. Individuals living across Harrisville should install certified reverse osmosis point of use water filtration systems to mitigate potential ingestion risks. Furthermore, residents should upgrade basement ventilation systems to proactively prevent potential soil vapor intrusion from migrating chemical plumes.
