Superfund Sites: Olin Chemical: Wilmington, MA

Olin Chemical: Wilmington, MA

Where: A 53-acre facility in the town of Wilmington, MA

When: The facility opened in 1953, held various chemical companies, and remained in operation until 1986. Contamination occurred all throughout that time.

What happened? Olin Chemical produced chemicals for the rubber and plastics industries at this site. Chemical waste was disposed of on-site, leading to groundwater contamination and seepage into bedrock. Although the facility closed in 1986, contamination continued. This led to the 2002 closure of the town wells that supplied local drinking water. The site was designated as a superfund in April 2006.
