Soil logs and grain size analysis from three sonic borings as part of the West Fork of the Hoquiam River Dam Removal and Groundwater Replacement Preliminary Design and Permitting project from 2023-06-19 to 2023-06-29 (NCEI Accession 0302303)
Drilling of the exploratory boreholes and installation of the monitoring well was completed by Anderson Environmental Contracting, LLC (AEC), using sonic drilling methods. An Aspect geologist was on-Site to observe the drilling and characterize the samples under the direction of a Washington State-licensed hydrogeologist (LHG). Aspect logged the boreholes in general accordance with ASTM International (ASTM) Method D2488, Standard Practice for Description and Identification of Soils (Visual-Manual Procedure). To confirm the soil type of Unit 3 (confined aquifer), Aspect submitted a representative soil sample to Hayre McElroy & Associates of Redmond, Washington, for laboratory analysis of grain-size distribution. Soil logs, a grain size analysis report, and an exploration log key are provided as PDF files.
