Aquifer Characterization

The Ground Water Characterization Program (GWCP) maps and assesses aquifers within specific areas as prioritized by the Ground Water Assessment Steering Committee.

To date, more than 8,000 wells have been visited and about 3,000 groundwater samples have been collected. These data have been used to compile 64 maps and reports that describe aquifer productivity, groundwater-flow systems, and groundwater quality.
