Brookline, New Hampshire, encompassing the 03033 zip code area, currently holds a critical environmental hazard designation due to historical industrial contamination. The region contains five active hazardous sites within five miles and a total of ten active sites within ten miles, indicating severe localized pollution. The closest facility, the E. J. Abbott Memorial Trust, is located just 1.96 miles from the residential center. This facility is currently classified by the Environmental Protection Agency under an active National Priorities List status, meaning long-term remedial cleanup operations are presently underway to mitigate persistent environmental threats. Other active remediation sites in close proximity include the O. K. Tool Company and the Savage Municipal Water Supply.

The primary contaminants of concern in this area are petroleum hydrocarbons. These toxic chemical compounds readily migrate through soil and groundwater, posing severe exposure risks. Prolonged ingestion or inhalation of petroleum hydrocarbons can cause neurological damage, respiratory distress, liver toxicity, and elevated cancer risks. Because these chemicals persist in groundwater systems, local well water is particularly vulnerable to contamination.

Given the active regulatory status and high concentration of neighboring hazard zones, residents must implement immediate safety protocols. Homeowners utilizing private wells must install whole-house water filtration systems certified to remove volatile organic compounds and petroleum byproducts. Furthermore, residents should test residential soil annually for hydrocarbon saturation before initiating agricultural or gardening activities. Finally, households must request the latest EPA remedial investigation reports regarding the E. J. Abbott Memorial Trust to monitor the expanding groundwater plume and adjust water consumption habits accordingly.
