Stage of Clean-up: Construction Underway
Conditions at listing (December l982): The Wells G & H Site covers about 500 acres in East Central Woburn, Massachusetts. Between l964 and l979, the wells provided approximately 25 percent of the drinking water for the town, primarily 25 homes and businesses in the southeastern portion. In l979, the State closed the wells after detecting four chlorinated solvents in the water. The concentration of total volatile organics was approximately 500 parts per billion. In l980, EPA began preliminary assessments of several industries in the area that may have affected Wells G & H. The investigation, later expanded to include an evaluation of the geology and ground water quality of North and East Woburn, was completed in June l982. Status (July l983): EPA has issued three orders against potentially responsible parties under Section 3013 of the Resource Conservation and Recovery Act (RCRA). The orders require the companies to conduct a hydrogeological investigation of their properties. EPA has also sent 15 letters (under Section 3007 of RCRA) to other companies within the study area requesting detailed information about their use of hazardous materials. EPA recently completed a Remedial Action Master Plan outlining the investigations needed to determine the full extent of cleanup required at the site. It will guide further actions at the site.
