hocomonco pond

FISHER ST

The 23-acre Hocomonco Pond site located in Westborough, Massachusetts is bordered on the northwest by Hocomonco Pond, a 27 acre shallow, freshwater pond which has long been used for recreational purposes. From 1928 until 1946 the site was used as a wood-treating and preservation operation. The business consisted of saturating wood products (e.g. telephone poles, railroad ties, pilings and fence posts) with creosote to preserve them. During the treatment process, excess creosote and wastes where discharged to an unlined pit, referred to herein as the "former lagoon". The former lagoon was excavated on the site to intercept and contain spillage and wastes from the wood treatment operations. As this lagoon became filled with creosote waste, sludges and water, the contents were then pumped into two low depressions located east of the site operations, near the west side of Otis Street. These depressions are referred to as "Kettle Pond". The available records indicate that no creosote was used or stored on the site after March 26, 1946. The last use of the site was as a cement plant where dry cement was distributed in bulk. The sediments, surface water and groundwater had shown creosote contamination. As of 2000, approximately 18,000 people and 6,534 households are located within the town of Westborough. Residential areas are located less than a half mile northeast and southeast of the site, although the adjacent property use is commercial.
