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...

This data-release component documents chemical analyses of soil samples collected by the U.S. Geological Survey (USGS) in Lakeport (Lake County, California) on July 12, 2022. Environmental samples were collected at selected sites in Lakeport to assess the effects of lead-based paint on soil chemistry. This sampling was made as part of a broader study to attribute sources of lead in soils in cooperation with the California Department of Toxic Substances Control (DTSC) for their Lead-Acid Battery Recycling Facility Investigation and Cleanup (LABRIC) program. A total of five soil samples plus one replicate across four properties were collected proximal to selected structures suspected to have legacy coatings of lead-based...

This data -release component documents field portable X-ray fluorescence (pXRF) measurements of lead and associated quality-control data for 19 samples of paint chips collected from structures suspected to have legacy coatings of lead-based paint in Lakeport (Lake County, California) during July 11-12, 2022. Environmental samples were collected at selected sites to assess the effects of lead-based paint on soil chemistry. This sampling was made as part of a broader study to attribute sources of lead in soils in cooperation with the California Department of Toxic Substances Control (DTSC) for their Lead-Acid Battery Recycling Facility Investigation and Cleanup (LABRIC) program. Lead concentrations for paint chips...
