File Number: #18-102386-00-PC
Project Address: 2200 SW 320th Street, Federal Way, WA
Prepared by: Ted Dimof - Bush, Roed & Hitchings
Date: March 18th, 2019
Attached is a summary of test results for the Tacoma Smelter Plume analysis.
Soil sampling was performed by Bush, Roed, & Hitchings on December 10th, 2019 where samples S-1 through S-
22 where collected at 2200 SW 320th Street, Federal Way, WA. Sampling methods followed the “Tacoma Smelter
Plume Model Remedies Guidance” dated June 2012.
Samples were tested by AM Test inc., a professional analytical service.
Based on the test results, elevated levels of arsenic and lead were not found at this site, therefore, cleanup will not
be required.
Below is a summary of the results:
Description: Parameter: Results: Comments:
Average Arsenic > 20 ppm 10.6 ppm Parameter not exceeded. Soil cleanup not required.
Maximum Arsenic > 40 ppm 33.0 ppm Parameter not exceeded. Soil cleanup not required.
Average Lead >250 ppm 28.1 ppm Parameter not exceeded. Soil cleanup not required.
Maximum Lead > 500 ppm 97.4 ppm Parameter not exceeded. Soil cleanup not required.
See attached for Form 1 & Form 2 from the “Tacoma Smelter Plume Model Remedies Guidance,” soil sampling
site plan, and laboratory test results.
