Health Consultation: Evaluation of Private Residential Drinking Water Wells Near Chamberlain Springs Alton, Belknap County, New Hampshire

摘要

The New Hampshire Department of Environmental Services (DES), Air Resources Division, Environmental Health Program (EHP) has completed this environmental data evaluation in response to a concern raised by the DES Drinking Water and Groundwater Bureau. Specifically, EHP evaluated residential drinking water well sample data for lead. These data were collected by DES and GZA GeoEnvironmental, Inc. (GZA) from January 19, 2006 until February 14, 2006 and summarized in an April 2006 GZA report entitled Lead Source Evaluation/Response to Preliminary Comments Chamberlain Springs. Chamberlain Springs LLC. (Chamberlain) is located on 166 Old Wolfeboro Road in Alton, New Hampshire. Chamberlain initially submitted a Bottled Water and Major Groundwater Withdrawal Application with DES in September, 2006. GZA, on behalf of Chamberlain, completed the Lead Source Evaluation to address DES comments to the initial withdrawal application (1). In 2006, EHP originally reviewed the DES and GZA drinking water quality sample data. Several samples detected lead at a concentration greater than the DES Ambient Groundwater Quality Standard for lead (15.0 ig/L) (1, 2). Accordingly, several residential well owners were notified by mail in March 2006 as to the possible adverse health effects resulting from exposure to lead in their drinking water wells. This health consultation further evaluates the potential for adverse health effects to occur from drinking water exposures to the naturally-occurring lead. This reevaluation was requested by the DES Drinking Water & Groundwater Bureau.
