Groundwater Monitoring Program for the City of Lawrenceville, Georgia

Cooperator: City of Lawrenceville, Georgia
Year started: 2002


Study area mapGround water from wells completed in fractured crystalline rock provides about 6 percent (0.12 million gallons per day) of the water supply to the city of Lawrenceville, Georgia. Additional ground-water withdrawal is planned in the Redland–Pew Creek and Alcovy River Basins. To enable informed decisions, city managers want to be able to quantify the effects (if any) of groundwater pumping on the surface-water resource as development increases. In addition, city managers recognize a need to collect data to help evaluate the effects of natural and human factors on stream-water quality and, thus, evaluate best-management practices.

To support long-term management goals, the city of Lawrenceville, in cooperation with the U.S. Geological Survey, established a hydrologic monitoring network. The network consists of ground water (regolith and bedrock wells) and surface water (streamgages) sites in the two newly developed basins and in a background basin (upper Apalachee River Basin) that is not influenced by the main pumping centers. An additional streamgage was installed in each of the basins and, beginning in 2006, in the Shoal Creek Basin. The data and information collected during the study can be used by local resource managers to develop a sustainable ground-water supply while minimizing the effects on surface-water resources. The data also will help in understanding changes in surface-water quality over time.
