Summary

The U.S. Geological Survey collected groundwater samples from 49 wells used for domestic and small system drinking water supplies and 10 monitoring wells in San Bernardino County, California in 2018. The wells were sampled for the Mojave Basin (MOBS) Shallow Aquifer Study Unit of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project’s assessment of the quality of groundwater resources used for domestic and small system drinking water supplies. Domestic and small-system wells commonly are screened at shallower depths than public-supply wells. The MOBS study unit covered the Upper, Middle, and Lower Mojave River groundwater basins, the El Mirage groundwater [...]

Purpose

This data release presents the data collected for the Groundwater Ambient Monitoring and Assessment Program Priority Basin Project MOBS Shallow Aquifer Study Unit in 2018. These data include: study unit and grid cell boundaries, site information for the 48 grid wells, and 11 understanding wells; water-quality results for samples collected from these 59 sites, water-quality results for quality-control samples collected from 17 sites, and 4 equipment blank quality control samples. Subsequent publications will present analysis and interpretation of these data. This document provides information necessary to understand the results presented in 10 tables provided in this data release.
