Health assessment for Holton Circle Ground Water Contamination Site, Londonderry, New Hampshire, Region 1. CERCLIS No. MHD981063860. 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). The contaminated wells that are considered part of the site lie along Holton Circle, a residential area in southwest Londonderry, New Hampshire. 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. 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. As noted in Section III, contaminants have been identified above acceptable levels in at least five residential wells. Consequently, it is recommended that investigations be initiated to identify and remediate the source, or sources, of ground water contamination.
