This addendum has been prepared to address the analysis for bioaccessible lead in residential soils. The original QAPP called for the collection of surface soils (0 to 2 inches below ground surface [bgs]) at up to 200 residential properties. At 10 percent of the surface sample locations, the vertical extent of contamination will be defined through the collection of subsurface soil samples at 0 to 6 inches bgs, 6 to 12 inches bgs, 12 to 18 inches bgs, and 18 to 24 inches bgs. Soil screening activities will generally follow the guidelines established in the Superfund Lead-Contaminated Residential Sites Handbook (EPA 2003). Screening samples will be dried, sieved and screened for lead by use of an x-ray fluorescence (XRF) spectrometer in accordance with EPA Method 6200. A subset of the screened surface and deep soil samples (10 percent) will be sent to the EPA Region 7 laboratory for confirmation analysis for lead, cadmium, and zinc by EPA Method 6010. To identify forms and potential origins of lead at the site, START will collect six samples for lead speciation analysis. For speciation analysis, composite surface soil samples (0 to 1 inch bgs), consisting of nine aliquots each, will be collected and submitted to the Laboratory of Environmental and Geological Studies (LEGS) at the University of Colorado in Boulder, Colorado. The original QAPP previously submitted by the Tetra Tech, Inc., Superfund Technical Assessment and Response Team (START) remains the primary guidance document for the continued remedial activities, but with the following modifications: In addition to surface and subsurface soil samples (described in the original QAPP), up to 14 samples will be submitted for bioaccessible lead in solids (soils) by inductively-coupled plasma/atomic emission spectrometry (ICP/AES) (EPA Standard Operating Procedure 3122.3F BioAv). This data will be used to improve the accuracy of exposure and risk calculations in support of human health risk assessment at the site. Surface soil samples (0 to 1 inch bgs) will be collected from residential yards in the same manner as previously described for pre-excavation soil screening/sampling for determination of lead (and other metals), with two exceptions: 1) these samples will only be collected from yards determined to have elevated lead X9025.15.0099.000 1 ------- levels, and 2) after drying, these samples will processed using a No. 60 sieve (250 micrometer [[j,m]), rather than the No. 10 sieve used for all other samples, to obtain the fine fraction of the sample for analysis. The EPA Technical Review Workgroup (TRW) and American Society for Testing and Materials (ASTM) have issued guidance on sieving (ASTM, 1998; EPA, 2000). The yards where these samples will be collected will be selected by EPA. Each sample for lead bioaccessibility analysis will be shipped to the laboratory in one, 8-ounce glass jar.
