Groundwater Monitoring Program for the Augusta–Richmond County Area, GA

Science Center Objects

Water supply in the Augusta–Richmond County, GA area is provided in part by three well fields that withdraw water from the Dublin–Midville aquifer system. 

The U.S. Geological Survey operates a groundwater and water-quality monitoring program to support water-management decisions and provide a basis for future groundwater modeling efforts while adding to regional characterization of groundwater conditions. Data will provide information to support water-management decisions and provide a basis for future groundwater modeling efforts while adding to the regional characterization of groundwater conditions.

Problem

Water supply in the Augusta–Richmond County area, Georgia is provided in part by three well fields that withdraw water from the Dublin–Midville aquifer system—a sand aquifer of Late Cretaceous age. Low levels of tetrachloroethene and trichloroethene have been detected in a supply well at the northernmost extent of well field number 2. To ensure that groundwater pumping does not adversely affect water levels in adjacent areas and to monitor ground-water quality, the U.S. Geological Survey operates a groundwater monitoring program for the Augusta–Richmond County area. Data from this network will provide information to support water-management decisions and provide a basis for future groundwater modeling efforts while adding to the regional characterization of ground-water conditions.

Objectives

  • Determine current groundwater levels, flow directions, and water quality of the Dublin-Midville aquifer system in the Augusta-Richmond County area.
  • Maintain a network of continuous water-level recorders at selected sites.
  • Collect synoptic water-level measurements and construct potentiometric-surface maps to establish seasonal flow gradients and directions.
  • Collect and analyze water samples from selected wells in and near well field number 2.
