Written by GovTribe AI · Mar 13, 2026

This technical document is an environmental site assessment report prepared by SME for Ubly Tractor Sales in Ubly, Michigan, detailing groundwater and soil gas contamination analysis. The report presents findings from monitoring well and soil gas sampling conducted on April 23-24, 2018, with additional samples collected on September 27, 2018. The assessment identifies volatile organic compounds (VOCs) at multiple locations across the property, with monitoring wells designated as SB101 through SB109, SB201 through SB205, and MW1 through MW5. The project includes graphical representations of the property layout, approximate contamination extent, and the locations of eight soil gas sampling points (SG1 through SG4 with multiple dates). The document compares detected concentrations against Michigan's Part 201 Generic Residential Cleanup Criteria (GRCC) standards to determine exceedances.

The contamination analysis reveals significant VOC concentrations at various depths, with several monitoring wells showing substantial exceedances of cleanup criteria. Notable contaminants include benzene, ethylbenzene, toluene, xylenes, naphthalene, and trimethylbenzene compounds, with concentrations ranging from below detection levels to over 22,700 micrograms per liter. The report identifies the approximate extent of groundwater contamination across the property and notes specific monitoring locations where all analytes remained below GRCC standards, providing a comprehensive baseline for remediation planning. The technical specifications indicate the assessment was finalized on December 31, 2018, with drawings prepared for 11" x 17" media reproduction at specified scales of 1" = 50' for the groundwater summary and 1" = 10' for the soil gas summary.

3. Results greater than reporting limits (RLs) are shown in BOLD. Results exceeding one or more criteria are shaded along with the corresponding criteria.

4. VOCs = volatile organic compounds.

5. NA = Not applicable; ID = Insufficient data to develop criterion; <RL = Analytical result was below laboratory reporting limit(s).

6. Concentrations were also compared to and found to be below Ambient Air Criteria and Screening Levels and Particulate Soil Inhalation Criteria.

GROUNDWATER & BACKFILL INFORMATION NOTES: 1. Soil samples were classified according to ASTM D2488, Standard Practice for Description and Identification of Soils (Visual-Manual Procedure) for environmental purposes only. Therefore, the boring logs and associated report(s) should not be used for geotechnical evaluation or design.

2. The indicated stratification lines are approximate. In situ, the transition between materials may be gradual.

3. Listed depths under the profile description are rounded to the nearest tenth of a foot (e.g. 5.75 = 5.8). Refer to the report and attachments for actual sample depths and/or intervals (where applicable).

4. No staining observed and no odors noted.
