Ground-water quality data for Oklahoma, 1981

The U.S. Geological Survey has collected data on Oklahoma's ground-water resources since 1934. Most of these data were collected as part of specific ground-water studies conducted in cooperation with various Federal, State, and local agencies. Ground-water quality data, as well as data on construction, yield, water levels, and other physical well parameters collected prior to 1981 are available from the U.S. Geological Survey, Oklahoma District Office.
Although water-quality data for wells, test holes, and springs have been published, they are scattered though a variety of reports and are not readily available on a statewide basis. The purpose of this report is to make available, annually, all of the ground-water quality data collected by the U.S. Geological Survey in the Sate of Oklahoma. This report contains ground-water quality data collected in 1981 from 524 sites in 15 counties, predominately in eastern Oklahoma.
