Classifications of groundwater monitoring wells as mixing with disposal water from percolation and evaporation ponds in the southwestern San Joaquin Valley, Kern County, California

The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board compiled and analyzed data to determine the approximate extent of plumes from produced water disposal ponds during 2016-2018 when airborne electromagnetic survey data were collected near the Midway-Sunset, Buena Vista, Elk Hills, McKittrick, Cymric, North Belridge, South Belridge, and Lost Hills Oil Fields in the southwestern San Joaquin Valley (SWSJV), Kern County, California. Data were compiled from documents available in the California State Water Resources Control Board GeoTracker database and the USGS National Water Information System. Geochemistry data collected at groundwater monitoring wells were analyzed to classify shallow groundwater samples as either mixing or not mixing with produced water disposed of on land. Classification criteria and sources of related technical information reported by well owners are described in this data release.
