Scarborough, Maine, falls under a critical environmental hazard designation due to a dense concentration of active remediation zones within the 04070 zip code. Within a ten-mile radius, fourteen hazardous sites require ongoing monitoring, including five highly active locations within just five miles. The EPA currently manages Colonial Cleaners as an active Superfund site located 4.5 miles from the local community. Surrounding facilities, such as South Side Cleaners Inc, SNV Cleaners, and the site of a CSX Railcar Sulfuric Acid Release, further compound the local risk profile.

The primary pollutants linked to these facilities consist of unspecified hazardous substances. Given the industrial history of commercial dry cleaning operations like Colonial Cleaners, these substances typically include volatile organic compounds, commonly known as VOCs, alongside industrial solvents. Prolonged exposure to these chemical agents, whether through groundwater contamination or vapor intrusion, can induce severe respiratory irritation, central nervous system depression, and elevated long-term carcinogenic risks for the local population. Colonial Cleaners remains in an active National Priorities List phase, meaning the EPA is actively executing long-term remedial responses to isolate and extract subterranean pollutants from the local water table.

To mitigate exposure risks, residents should immediately install certified reverse osmosis filtration systems for all drinking water sources to intercept potential groundwater migration. Individuals utilizing private wells must commission annual independent laboratory testing specifically targeting volatile organic compounds and heavy metals. Furthermore, homeowners should seal basement cracks and foundation gaps with elastomeric compounds to prevent subterranean vapor intrusion from migrating chemical plumes.
