Aquifer test data for the Belridge multiple-well monitoring site (BWSD), Kern County, California Aquifer test data for the Belridge multiple-well monitoring site (BWSD), Kern County, California

To determine aquifer characteristics, pneumatic slug tests were performed on selected zones and aquifers at a monitoring site near the North and South Belridge oil fields in the Southern San Joaquin Valley in Kern County. On November 19th and 20th, 2018, pneumatic slug tests were performed at five monitoring wells located at the multiple-well groundwater-monitoring site BWSD (28S/21E...
