GeoTest Services, Inc. Date 10 30 2019 North Sound Behavioral Health Env. Sampling Project Number 19-0740 ANALYTICAL RESULTS IMetals: IVarious MTCA-5 metals were identified in the soil sample; however, metals are naturally occurring and common in all soils. All identified metal concentrations would appear to be I consistent with natural background levels expected for the region based on the reference tables provided by the Washington State Department of Ecology and the US Geological Survey. 111 The following table provides a summary of sampling results: TABLE 1 I SUMMARY OF LABORATORY ANALYSIS. North Sound Behavioral Health All soil sample results and limits are in milligrams per kilogram(MG/KG).Please refer to the individual analytical laboratory I Sample# result sheets for a complete list of analysis and results.

Action Level -Indicates minimum level of contaminates within the soil or groundwater which may require Cleanup action by the Washington State Department of Ecology,Model Toxics Control Act(MTCA)Cleanup Regulation Chapter I 173-340 WAC,(Revised June 2016),Tables 720-1 and 740-1 cleanup levels.For substances not listed in the Method A Tables,Method B values listed in the Cleanup Levels and Risk Calibration(CLARC)under the MTCA Regulation,updated 2015,were referenced. I CONCLUSIONS ISoils sampled associated with the above referenced project returned results either non-detect or below MTCA Method A Soil Clean Up Levels for Unrestricted Land Uses for MTCA-5 Metals.
