NPL Site Narrative for Hocomonco Pond

Westborough, Massachusetts

Federal Register Notice:  September 08, 1983

Conditions at listing (December 1982): Hocomonco was a recreational pond in Westborough, Massachusetts, until the State closed it in 1980. It is privately owned. From 1920 to 1963, the site was the location of wood-treating and asphalt-batching operations. Past disposal practices resulted in creosote and phenol contamination of ground water, surface water, and sediments and soils in the pond and on its shore. A municipal well, the Otis Street Well, is located 1,500 feet to the northwest of the pond. To date, no contaminants have been detected in this well, which is sampled every 6 months.

Status (July 1983): EPA recently completed a Remedial Action Master Plan outlining the investigations needed to determine the full extent of cleanup required at the site.

The owners of the property contracted for a study of the historical use of the land and the processing operations and disposal practices associated with each use. The contractor also recommended an approach to investigation of the area.
