Summary
This data release documents chemical analyses of environmental samples collected by the U.S. Geological Survey (USGS) 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. Results of soil sampling and chemical analyses are included in the data-release component entitled "Soils chemistry from selected sites in Lakeport, Lake County, California" linked below. [...]

Results of paint-chip screening data and associated quality control are included in the data-release component entitled "Field portable X-ray fluorescence and associated quality-control data for paint chips sampled from selected sites in Lakeport, Lake County, California" linked below. This study would not have been possible without volunteers who provided field support and allowed access to sample sites.

Purpose
These data were collected to characterize lead and other elements diagnostic of lead sources in soils potentially affected by weathering of lead-based paint from proximal structures. This investigation is part of a broader cooperative study between USGS and DTSC to identify geochemical characteristics of soils affected by lead from battery recycling facilities across California. Results are intended to be used to develop a reliable methodology for attribution of sources of lead in soils across California and not for regulatory compliance monitoring or associated activities.
