The zip code area 01904 in Lynn, Massachusetts, operates under a critical environmental hazard designation. There are 16 active hazard sites within a radius of five miles and 51 within ten miles. The notable Ash Street Tannery (Former) is an active EPA Superfund site located five miles away, functioning alongside closer active sites including Whyte’s Laundry, Salem Acres, and US Air Force Plant 29. The primary pollutants registered in this sector are classified as unspecified hazardous substances. This specific EPA designation indicates complex industrial waste profiles containing heavy metals, volatile organic compounds, or legacy solvents. Human exposure to these aggregated contaminants occurs through groundwater leaching, soil vapor intrusion, or particulate dispersion. Long-term exposure to such chemical profiles can disrupt endocrine systems, impair respiratory function, and increase the statistical risk of cellular degradation among local residents.

The Ash Street Tannery and surrounding properties remain under active National Priorities List regulatory status. This active classification indicates that site assessment, remedial investigation, and ongoing mitigation phases are currently managed by federal authorities to control further environmental migration.

Given the density of active contamination and heavy industrial zones, residents must implement localized safety protocols immediately. Residents should install a certified reverse osmosis water filtration system to intercept potential municipal or private well water contamination. Additionally, individuals must seal basement foundation cracks to prevent subsurface vapor intrusion from migrating chemical plumes. Finally, households should utilize raised garden beds with imported commercial topsoil for all agricultural activities to avoid direct contact with potentially degraded native soil.
