RE:Letter Report for Soil Sampling
ANK Short Plat –Soil Sampling
29850 18th Ave South,
Federal Way, Washington, 98003
Dear Mr.Woldetekle,
Krazan and Associates (Krazan)is providing this Letter Report in reference to limited sampling of soil at
the referenced address located in Federal Way,Washington.Sample collection was conducted by Krazan
representative Mr.Jessep Englert on September 13, 2023. This sampling was performed in accordance
with state regulatory requirements, and was limited to the client-defined subject area located at 29850 18th
Avenue South, Federal Way, Washington.Contaminant of concern (COC) analysis and number of
samples were based on the Tacoma Smelter Plume Guidance documentation provided by the Washington
State Department of Ecology (WDOE).
1.0 ANALYTICAL RESULTS
1.1 Project Scope
Based on sampling requirements,thirty-one (31)discrete soil samples were collected in an evenly
distributed grid-like pattern to best characterize the site and one (1) composite duff sample, consisting of
six (6) duff sub-samples,was collected beneath the client defined tree assumed to be staying on site.
1.2 Sampling Methodology
The samples were collected by carefully collecting thirty-one (31) discrete soil samples with a clean
stainless-steel sampler with the composite duff sample being mixed in a stainless-steel container. The
samples were placed in clean glass sample containers provided by the laboratory.Sample containers were
then placed in an iced cooler for transportation to the laboratory.The sampling instrument was treated
between samples with a rinsate wash to decontaminate the tool and minimize the potential cross
contamination of subsequent samples, with all rinsate wash returned to the Krazan lab for proper disposal.
Data pertinent to the sample (e.g., date,sample number, analytical procedures) was recorded on a chain-
of-custody form.
1.3 Laboratory Analysis
A total of thirty-one (31)discrete soil samples and one (1) composite duff sample were collected from the
site and delivered to Libby Environmental Laboratory in Olympia, Washington,and Onsite
Environmental, Inc. in Redmond, Washington,under chain-of-custody protocol for analysis.Libby
Environmental Laboratory and Onsite Environmental Laboratory are Washington State-accredited
laboratories.As per client specifications,the sample was analyzed for Total Arsenic and Total Lead by

method EPA 6010D.The Laboratory analytical data report and chain-of-custody form are provided in
Appendix A.
1.4 Laboratory Sample Results
Table 1 includes the sample number, sample location, sample description,and analyte concentrations for
the arsenic and lead analyses.
