Summary

High concentrations of uranium were detected in samples from wells used for domestic drinking water supplies in the San Joaquin Valley. Of 163 domestic wells sampled by the California Groundwater Ambient Monitoring and Assessment Program Priority Basin Project (GAMA-PBP) and the National Water Quality Program (NWQP) in 2008-2015, 26 percent had uranium concentrations greater than the U.S. Environmental Protection Agency maximum contaminant level (EPA MCL) of 30 µg/L, with 13 percent of the wells having uranium concentration between 100 µg/L and 450 µg/L. To evaluate the potential anthropogenic and geologic causes of these anomalously high uranium concentrations, Rosen and others (2019) compiled water quality and ancillary data for [...]

Purpose

This Data Release contains compiled groundwater quality and ancillary data for the 257 well sites included in the evaluation of occurrence of uranium in groundwater used for domestic drinking water supply in the eastern San Joaquin Valley, California by Rosen and others (2019). The water-quality data in this data release were originally collected in 1993-2018 by the California Groundwater Ambient Monitoring and Assessment Program Priority Basin Project (GAMA-PBP) and the National Water Quality Program (NWQP) as part of studies of water quality in groundwater resources used for drinking water supplies in the San Joaquin Valley, California. The water-quality data were previously published and also are publicly available through the USGS National Water Information System and the California State Water Resources Control Board Groundwater Information System, but are presented again in this Data Release for the convenience of providing the complete dataset used by Rosen and others (2019).
