Health assessment for Holton Circle, Londonderry, Rockingham County, New Hampshire, Region 1. CERCLIS No. NHD981063860 (ADDENDUM). Preliminary report
The Holton Circle Ground Water Contamination Site (Holton Circle Site), defined as a series of residential wells and one commercial well that have been contaminated with chloride and various volatile organic chemicals (VOCs) from an unidentified source, is listed on the U.S. Environmental Protection Agency's (EPA) National Priorities List (NPL). Sampling and analysis at the Holton Circle Site have been conducted by the NH WSPCC and NUS Corporation. Sampling by NH WSPCC has been limited to water supply well analyses for VOCs and inorganic analytes. The environmental pathway of primary concern relative to contaminant migration at the Holton Circle Site is the leaching of contaminants from an unknown source to groundwater, although the Town Garage appears to be a likely contaminant source. Based upon the available information, the Holton Circle Ground Water Contamination NPL Site is considered to be of potential public health concern because of the risk to public health caused by potential exposure to hazardous substances at concentrations that may result in adverse health effects if exposure were to occur over an extended period of time. There do not appear to be any sources of acute health risks associated with the Holton Circle Ground Water Contamination Site.
