Methods and Hydrogeologic Data From Test Drilling and Geophysical Logging Survey in the Lawrenceville, Georgia Area.

摘要

This report describes the methods used and data resulting from test drilling and geophysical logging surveys conducted between December 1994 and October 2001. Included in this report are: (1) methods of collecting and analyzing data; (2) fracture data showing the depth, nature, and yield of different types of water-bearing fractures; (3) aquifer-test data showing the yield of wells and the direction and magnitude of drawdown; (4) packer-test data showing the hydraulic response among high-yield fractures; and (5) water-level data showing fluctuations in ground-water levels in response to seasonal variations in precipitation and from local ground-water withdrawals.
