MetadataShow full item record
A Lower Floridan aquifer production well was successfully completed at Harris Trail Rd. Richmond Hill, Ga. The test drilling used data developed during the drilling of the USGS test well (35P109) at the Richmond Hill, Ga. Sterling Creek Treatment Plant, and previously published studies in Chatham County by the United States Geological Survey (USGS). A hydrogeologic characterization was performed at Harris Trail Road, which included drilling, field water quality monitoring, borehole geophysical logging, and a 72Hr. aquifer test. The results of the testing defined the top, base and thickness of the Upper Floridan aquifer, the middle confining layer, the fresh water Lower Floridan aquifer and the base of the Floridan Aquifer System at Richmond Hill, Ga. The testing also demonstrated that the Lower Floridan aquifer is capable of supplying 1500 gallons per minute of good quality water without treatment for the City of Richmond Hill with minimal impact on water levels in the Upper Floridan aquifer.
