City of Concord, NH (City-wide Groundwater Development)

The Project

The City of Concord Public Works is seeking to develop additional potable water supplies to meet future water supply demands. Therefore, the City has undertaken a water supply study designed to investigate the potential for developing additional groundwater and surface water resources.  EGGI was retained to investigate the potential availability of groundwater sources that could be derived from unconsolidated sand and gravel deposits existing within a 1,000-foot buffer around the entire City Limits.

Tasks undertaken in this initial work phase included the following:

Status/Results:

  • Background data review;
  • Detailed investigation of the surficial geology;
  • Review of socio-economic considerations relative to the practicality of developing groundwater resources (i.e., availability of land, distance from existing distribution systems, etc.);
  • Identification of contaminant threats and existing land uses having the potential to degrade groundwater quality; and
  • Identification of sub-areas (zones) considered to have a favorable potential for developing potable groundwater resources from sand and gravel aquifers.

The data generated in carrying out these work tasks were synthesized in order that a comprehensive assessment of the potential groundwater resources available for development within the Study Area could be completed. Collectively, the data analyzed served to identify seven zones considered favorable for the development of groundwater resources within the City of Concord.
