About this file
This document is a Triage Summary Report and Boring Log prepared by Sagasser & Associates, Inc. for a environmental assessment project at Surplus Inc. located at 777 W. Houghton Lake Drive, Prudenville, Roscommon County, Michigan (Project #41305-00846-2B). The report includes geotechnical investigation data documenting soil conditions and contamination findings at the site. The boring log indicates a single borehole (TB-1) was drilled to a depth of 10 feet using direct push probe methodology on September 13, 2019. The site is located in Denton Township, Range 22-N, Section 3-W, with coordinates at 417172.924 Northing and 607330.542 Easting using the Michigan GeoRef datum, and a ground elevation of 1144.68 feet (NAVD88).
The boring log reveals multiple soil layers with varying lithologic descriptions, including sand, gravel, and clay compositions at different depths. Field sampling and analysis using photoionization detection (PID) identified petroleum contamination indicators, with soil samples showing elevated readings ranging from 3 to 378 ppm, particularly at depths between 2-4 feet where oil-soil staining and sheen were visually observed. A 1-inch PVC casing with 0.10-slot screen was installed in the borehole, with the annulus sealed using bentonite backfill. Groundwater was encountered at approximately 2 feet below ground level, indicating shallow water table conditions at the site.
