Davis, T.A., Kulongoski, J.T., and McMahon, P.B., 2016, Produced water chemistry data for samples from four petroleum wells, Southern San Joaquin Valley, California, 2014: U.S. Geological Survey data release,


The U.S. Geological Survey (USGS) in cooperation with the California State Water Resources Control Board collected produced water samples from four petroleum wells in the southern San Joaquin Valley on November 5, 2014. This digital dataset contains the site information, analyzing laboratories and methods, and water chemistry and quality control results for these samples. Water chemistry results include concentrations of dissolved hydrocarbon gases and their isotopic composition; concentrations of inorganic constituents including salinity, major ions, and nutrients; dissolved organic carbon; and stable isotopes of water and strontium dissolved in water. Samples were analyzed by 5 laboratories operated or contracted by the USGS.

Produced water samples were collected as part of a reconnaissance study to evaluate the potential utility of tracers for assessing the effects of oil and gas development on California groundwater. Results of the exploratory study are intended to inform the design of a regional groundwater monitoring program that will be implemented as part of California Senate Bill 4 (SB4 of 2013).
