Cumberland, Rhode Island (ZIP 02864) carries a critical environmental hazard designation due to a severe concentration of industrial waste sites. The area falls within the contamination radius of 57 hazardous facilities within ten miles, including 14 within a five-mile radius. The Courtois Sand & Gravel site represents a major regional threat, situated three miles away. Nearby facilities, including Lonza/Universal Chemical, Peterson/Puritan, Inc., and the Cumberland Municipal Landfill, also maintain active EPA contamination statuses at distances under two miles. The Courtois Sand & Gravel site currently holds an active National Priorities List status, meaning the Environmental Protection Agency is actively conducting remediation efforts and the location has not yet met cleanup targets. The EPA classifies the primary contaminants at this facility as unspecified hazardous substances. Such industrial mixtures typically involve volatile organic compounds and heavy metals that migrate through groundwater or volatilize into soil vapor. Chronic exposure to these chemicals can increase risks for neurological disruption, respiratory disease, and systemic organ damage when ingested through tap water or inhaled via vapor intrusion.

Given the high density of active contamination zones, residents must implement immediate mitigation strategies. Households relying on private wells must schedule comprehensive water testing specifically for volatile organic compounds and heavy metals through a state-certified laboratory. Residents should install reverse osmosis point-of-entry water filtration systems to intercept groundwater contaminants before they reach residential plumbing. Furthermore, homeowners should hire certified technicians to conduct indoor air quality testing to detect potential sub-slab vapor intrusion originating from migrating underground chemical plumes.
