KGS Online Groundwater-Quality Data Reports

Groundwater-quality data and sample-site information were obtained from the Kentucky Groundwater Data Repository, a database that KSG maintains to collect and preserve groundwater information throughout the state. The data have been gathered from numerous sources. The samples were collected at various times and analyzed by different laboratories for a variety of projects and purposes. There was no uniformity of reporting methods. KGS has standardized analyte names and analysis units in order to make the data more accessible to the public. No warranty is expressed or implied by KGS as to their accuracy or completeness. KGS staff cannot check every record, and we rely on our customers and end-users to help us correct errors and omissions. Please notify KGS of any errors or problems that you encounter using these data at 859-257-5500 x 162, or by e-mail at bdavidson@uky.edu.

Explanations and Definitions

AKGWA Number and Site Number: The AKGWA number is a unique site identification number assigned by the Kentucky Division of Water. However, not all sites represented in the Kentucky Groundwater Data Repository have AKGWA numbers; therefore Site Numbers are used to identify locations where groundwater samples have been collected.

Surface Elevation, Water Level, and Depth: Surface elevation is reported as feet above mean sea level. Water level and depth are reported as feet below top of casing. Note that depth refers to total well depth, not necessarily the depth to the water-producing zone.

Collection Date: Many wells and springs have been sampled repeatedly over time. If your project is time-sensitive, be sure to limit the results of your search to the appropriate time interval.

Regulatory Program: Samples collected for regulatory programs such as RCRA, CERCLA, State CERCLA, Solid Waste, or UST may be anomalous. Analytical results from these samples should not be used to infer ambient groundwater-quality. Samples collected for the Groundwater Program are part of the Kentucky Division of Water's groundwater monitoring program; these site locations were specifically chosen to avoid known sources of contamination.

Values below detection: A "<" sign indicates the analyte concentration was less than the analytical detection limit. For example, a result of "<0.003" mg/L indicates that the concentration was below a detection limit of 0.003 mg/L. Detection limits change over time as analytical methods improve. Some older analyses may have detection limits that are greater than current health-based water-quality standards.

Aqueous State: The aqueous state of a sample refers to whether it was filtered or not. T (Total) indicates that the sample not filtered, and therefore the analyte concentration includes both material in true aqueous solution and material associated with suspended solids. D (Dissolved) indicates that the sample was filtered, and the analysis reports only material in true aqueous solution.

Median Value: The median concentration at a site is calculated using only values that are above analytical detection limits.
