The California Gulch Superfund Site in Leadville, Colorado was added to the National Priority List (NPL) in 1983. It is an historic mining and smelting site that is currently the focus of extensive studies on soil lead contamination and bioavailability. Studies of ground and surface water impacts are also in progress. Personnel from the Environmental Protection Agencies (EPA) Environmental Monitoring Systems Laboratory at Las Vegas (EMSL-LV), the Denver office of Roy F. Weston, Inc., and Geostat Systems, Inc. (GSI) used field-portable X-ray fluorescence (FPXRF) to determine the spatial distribution of lead concentrations in residential soils. The report details the FPXRF program sample collection, preparation, and analysis procedures, database management, and program quality assurance efforts at Leadville. The program clearly demonstrates that small, field portable XRF instrumentation can produce large quantities of acceptable quality data in a timely and cost-efficient manner when used properly.
