The 01830 zip code area of Haverhill, Massachusetts, carries a critical environmental hazard designation due to extensive nearby industrial contamination. Residents live within a ten-mile radius of twenty-six active hazard zones, with ten sites located less than five miles away. The nearest major location, the AT & T (FORMER) facility, sits 4.7 miles from the area center and remains on the active National Priorities List, indicating that Environmental Protection Agency cleanup and monitoring operations are currently ongoing. Other active sites severely impacting the immediate vicinity include Haverhill Salvage, Hoyt & Worthen Tanning Corp, Groveland Street Solvents, and Groveland Wells. The primary threats at the AT & T (FORMER) site and surrounding facilities involve unspecified hazardous substances and industrial solvents historically used in manufacturing and tanning operations.

When these chemical compounds leach into soil and groundwater, chronic exposure can severely compromise human health. Long-term ingestion or inhalation of these unspecified industrial byproducts can lead to neurological issues, respiratory irritation, hepatic toxicity, and elevated risks of certain cancers. Volatile organic compounds from such solvents may also vaporize and infiltrate residential basements through soil vapor intrusion. Given the extreme concentration of active environmental threats, residents should implement immediate safety protocols. Individuals relying on private wells must schedule independent water testing for volatile organic compounds and heavy metals immediately. Residents should install certified reverse osmosis water filtration systems for all drinking and cooking water sources. Finally, homeowners should hire certified environmental inspectors to assess basements for chemical vapor intrusion.
