Abstract
During 2002, a cooperative study between the U.S. Geological Survey and the City of Lawrenceville, Georgia, was initiated to monitor groundwater levels and streamflow in areas of potential groundwater-resource development. Little is known about the effects of pumping on groundwater levels and streamflow in Piedmont regolith-fractured bedrock hydrogeologic settings. There-fore, a monitoring network of observation wells and streamgaging stations was installed to collect hydrologic data from two watersheds: one 9.95 square miles (mi2) in area; and another 7.5 mi2 in area, near Lawrenceville. Monitoring data will be collected both before and after groundwater pumping is initiated in an attempt to deter-mine the sustainability of groundwater and surface-water resources within these watersheds. From the data collected thus far, stream baseflow trends are similar to ground-water level trends in the aquifer; and climate-induced water-level declines in the aquifer appear to parallel base-flow trends in streams, especially in upland reaches near surface-water divides. Continued monitoring of these streams and wells will be important in determining the potential effects of pumping on groundwater and surface-water resources in a regolith-fractured bedrock hydro-geologic setting.
