Borehole data-collection methods applicable for the regional observation and monitor well program, Southwest Florida Water Management District

Management of ground-water resources within the Southwest Florida Water Management District requires that hydrogeologic characteristics of water-bearing rocks and quality characteristics of water be described. Wells for the District 's Regional Observation and Monitor Well Program are drilled specifically to collect data to describe the ground-water resource. Suggested borehole data-collection methods for these wells include drilling in stages; running geophysical logs at the completion of each stage; collection of water-level and specific-conductance data before, during, and after a day 's drilling; specific-capacity determinations after a day 's drilling; and placing a packer in the gypsiferous and anhydritic limestone and dolomite for water-level and water-quality data.
