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 paint. This component of the data release contains two tab-delimited text files and associated metadata describing results. The Lakeport_soils.txt file contains results of soil chemical analyses for individual soil samples sieved to three size fractions (less than 2 millimeters [mm], 0.063 mm to 0.25 mm, and less than 0.063 mm). Concentrations of elements included in this data release analyzed by inductively coupled plasma mass spectrometry or optical-emission spectrometry after multi-acid digestion include: aluminum, calcium, iron, potassium, magnesium, sodium, sulfur, titanium, silver, arsenic, barium, beryllium, bismuth, cadmium, cerium, cobalt, cesium, copper, gallium, indium, lithium, manganese, molybdenum, niobium, nickel, phosphorus, lead, rubidium, antimony, scandium, selenium, tin, strontium, tantalum, tellurium, thorium, thallium, uranium, vanadium, tungsten, and zinc. The Lakeport_soils_replicates.txt file contains comparison results for the aforementioned three size fractions for one of the soils that was sampled in duplicate.
