Charlestown, Rhode Island, falls under a critical hazard designation due to a high concentration of active environmental remediation sites. Located in ZIP code 02813, the area contains eight hazardous facilities within five miles, underscoring significant environmental liabilities. The nearest major facility is the Beaver River Dump, an active site located 4.2 miles away. Under the Environmental Protection Agency, this location remains on the active National Priorities List, indicating that investigation and cleanup operations are currently ongoing. The broader region features twelve active sites within a ten-mile radius, including areas near Ninigret National Wildlife Refuge and Ninigret Park.

The EPA lists the primary pollutants at the Beaver River Dump as unspecified hazardous substances. While exact chemical profiles remain unverified in public registries, legacy dumps of this nature typically contain heavy metals, volatile organic compounds, or industrial solvents. When left unmitigated, these substances can leach into local groundwater supplies or volatilize into the soil, posing long-term risks of neurological, respiratory, or systemic toxic exposure for surrounding populations relying on private wells.

Given the severe density of local active environmental sites, residents should immediately implement these protective measures. Homeowners must test private well water annually for dissolved heavy metals and dangerous volatile organic compounds using a certified state laboratory. Additionally, residents should proactively install certified reverse osmosis filtration systems for all potable water sources in the home. Finally, locals should regularly consult the EPA database for updates on groundwater migration testing at the Beaver River Dump to ensure neighborhood aquifers remain entirely uncontaminated.
