ADDENDUM NO. 1
QUALITY ASSURANCE PROJECT PLAN
CANEY RESIDENTIAL YARDS SITE - CANEY, MONTGOMERY COUNTY, KANSAS
This document is an addendum to the Quality Assurance Project Plan (QAPP) dated
April 22, 2015, for the Caney Residential Yards site in Montgomery County, Kansas. 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

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.
