Logs of Test Holes and Wells

The logs of test holes and wells drilled in Sumner County are given on the pages that follow. Included are logs of 296 test holes of the State and Federal Geological Surveys, which were drilled with a hydraulic-rotary drill rig or bored with a power auger, and logs of 66 test holes and wells drilled by contractors. Logs of 4 test holes listed in Table 11 are not given. Unless otherwise stated in the log heading, the well or test hole was drilled by the State and Federal Geological Surveys. The sample logs are of wells from which cuttings were collected and studied in the laboratory. The drillers logs are of wells from which cuttings were examined only in the field, and the lithology determined at least in part by drilling characteristics.
