BOX 1666 303 N. FOURTH P.O.BOX 1666 January 14, 1994 Mason County Department of Community Development Don Brush P.O. Box 578 Shelton, WA 98584 RE: Walmart Site Soil Characterization Dear Don Brush: The Mason County Department of Health Services (MCDHS) has, at your request, reviewed test results on soils from the future Walmart site located outside of Shelton in Mason County, Washington. These soil tests were conducted for Washington Stata Department of Ecology (WSDOE) review, and were requested, in part, due to the proximity of the site to the Goose Lake area where the Rayonier Shelton Pulp Mill had disposed of waste materials from the pulp mill and other Rayonier facilities. The tests requested by the WSDOE were projected to reveal suspected contaminants that would have resulted from the Rayonier disposal activities, should any contamination have taken place. Analytical test results included analysis for TCLP Metals; Resin Acids, Fatty Acids, and Bleach Plant Derivatives; and Chlorinated Phenolic Organic Compounds. Four samples were requested- -two from the Walmart site where soils are being excavated, and two from materials which were previously excavated. It was reported to the MCDHS by Tom Jones of RZA AGRA, Inc. , that the samples were taken from locations that would accurately represent the soils that are being removed from the Walmart site, including two samples from the side of an on-site excavation pit and two from excavated materials now located at the John Burnett Island Lake gravel pit. The results indicate non-detectable levels of suspected contaminants. In sample PS-1, the Method Reporting Limits were elevated because of the low percent solids in the samples received. The detection of acids in sample PS-4- -tested for resin acids, fatty acids, and bleach plant derivatives- -was predicted to be due to naturally occurring levels due to the acidic nature of .the decomposition process of the materials. Rusty Post of the WSDOE informed the MCDHS that he had not verified from Loree Randle and Dick Heggen of the WSDOE that the tests conducted included the complete list requested by the WSDOE. Mr. Post indicated that Total Metals would have been more appropriate than TCLP Metals; however, he stated that the tests appear Page 1 of 2 ©Recycled Y.too/• y/•aoa/o r 1 appropriate for indicating whether the soils contained contaminants of concern. Mr. Post also told the MCDHS that the WSDOE had not received a sampling report along with the test results; however, the MCDHS consults with RZA AGRA regarding field information, including sampling locations, suggested acceptable sampling methods. Given this information, the MCDHS would concur with the WSDOE that the materials do not appear to have been affected by contaminants from Rayonier disposal activities near Goose Lake, and that the current testing information indicates that the development activities of relocating materials from the Walmart site to a nearby Kneeland site, which had been pre-screened by the Mason County Department of General Services, should not be held up at this time. The MCDHS will continue to consult with the WSDOE regarding final determinations on the soil analysis results and the acceptability of the materials for uses at the Kneeland site or other sites within Mason County. Please contact Mike Tokos of the MCDHS with any questions or correspondence regarding the MCDHS involvement in this analytical review.
