GeoTest Services, Inc. Date 10/30/2019 North Sound Behavioral Health Env.Sampling Project Number 19-0740 Sampling equipment was cleaned and gloves were changed between each collection point to prevent cross-contamination. The soil sample containers consisted of two standard 8 oz. wide I mouth glass jars with Teflon lined lids. Each sample was labeled, immediately placed in a cooler and chilled to approximately 4 degrees Celsius. The samples were immediately delivered to ALS Laboratory Group, located in Everett, Washington. DOE recommended sample collecting, handling, chain of custody records and protocol were maintained throughout the project. Standard laboratory analytical analysis required 4 full business days to complete. Our field screening consisted of visual inspection of the soils within the excavations and olfactory "sniff testing". SUBSURFACE SOIL CONDITIONS Approximately three inches of asphalt was present at both exploration locations. The asphalt is underlain by dense, brown,dry sandy gravel interpreted as crushed surfacing base course. Dense to very dense, brown/grey, damp, gravelly sand interpreted as native glacial till is present from approximately two feet below present ground and extended to the termination depth of 9.5 feet.
