PUBLIC MEETING ANNOUNCEMENT

Concord, NH – The New Hampshire Department of Environmental Services (DES) will be hosting an informational meeting regarding the recent investigation of environmental conditions in the vicinity of 77 to 83 Liberty Hill Road at 7 pm, Thursday, August 10, 2006, at the Gilford Town Hall, Conference Room A/B.

In 2004, DES and KeySpan Energy Delivery (KeySpan) learned that a gravel pit located along Liberty Hill Road was used to dispose of waste coal tar from the former Laconia manufactured gas plant in the 1950s. Between 2004 and 2006, KeySpan (whose predecessor company operated and dismantled the plant) conducted an investigation under the oversight of DES. The results of the investigation were summarized in a Site Investigation Report submitted to DES in June 2006, and will be presented at the public meeting.

During the investigation, samples of groundwater, soil, sediment, surface water, soil gas and indoor air were collected and tested. Drinking water wells were tested at the properties in the vicinity of the site. No contaminants were detected in any drinking water wells. Coal tar in soil and groundwater was found adjacent to and potentially beneath some of the homes on the south side of Liberty Hill Road (the side of the street with odd numbered houses). Despite its presence on some of the properties, no significant current exposure pathway to coal tar has been identified; however, some soil and groundwater remediation will be required.

If you have any questions regarding the site or the public meeting, please contact John Regan, P.G., Supervisor of the State Sites Section for the New Hampshire Department of Environmental Services, Waste Management Division at (603) 271-3744.
