GEOTECHNICAL INVESTIGATION SUMMARY

Geotechnical Investigation Summary AMCO #1209 Site Croswell, Michigan

TECHNICAL MEMORANDUM

DATE: June 2021

TO: Michigan Department of Environment, Great Lakes, and Energy (EGLE)

FROM: Nicholas Langlais, P.E. (MI No. 6201309267)

REVIEWED BY: Richard Egan, P.E. (ME)

SUBJECT: Geotechnical Investigation Summary AMCO #1209 Site

PROJECT: 3293182027

INTRODUCTION

Wood Environment & Infrastructure Solutions, Inc. (Wood) is pleased to present this Geotechnical Investigation Summary to the Michigan Department of Environment, Great Lakes, and Energy (EGLE) to characterize the subsurface and obtain geotechnical data to support remedial design and construction at the AMCO #1209 Site in Croswell, Michigan (i.e., the Site).

It is anticipated that remedial activities will consist of excavation and disposal of Non-aqueous Phase Liquid (NAPL)-impacted soils on Ward Street, between North Howard Street to the west and Brown Street to the east. As such geotechnical/structural design of temporary excavation support will be required to perform the excavation and backfilling activities.

The following sections of this Technical Memorandum summarize the geotechnical exploration and laboratory testing programs and describe the subsurface conditions encountered.

GEOTECHNICAL INVESTIGATION PROGRAM

Wood completed five geotechnical borings, designated B-1 through B-5, at the Site from October 12-20, 2020. Boring locations were selected in relation to existing Site features and under the constraints of drill rig access and utility conflicts. The approximate as-drilled geotechnical boring locations are depicted in Figure 1.

A Wood geologist directed the drilling operations at the borings, collected soil samples, and logged subsurface conditions encountered. Job Site Services of Bay City, Michigan provided drilling services using a Mobile B-57 rig. The drilling was performed via hollow-stem auger methods (4.25-inch inside diameter, 8-inch outside diameter). The borings were drilled to depths ranging from approximately 44 to 72 feet below ground surface (bgs). As each boring was advanced, Standard Penetration Tests (SPTs) were generally performed at continuous to near-continuous intervals through the upper 10 feet of overburden and at 5-foot intervals thereafter. SPTs were performed in general accordance with American Society of Testing and Materials (ASTM) D 1586, Standard Test Method for Penetration Test and Split-Barrel Sampling of Soils. Soil samples were described using procedures outlined in ASTM D 2488, Standard Practice for Description and Identification of Soils (Visual-Manual Procedure). Shelby tube samples (3-inch diameter) were obtained at selected intervals within fine-grained soils. Shelby tubes were collected in general accordance with ASTM D 1587, Standard Practice for Thin- Walled Tube Sampling of Soils for Geotechnical Purposes. Representative soil samples collected from the SPTs were sealed in glass jars and returned to the office for further review, classification, and submission/shipment to the geotechnical laboratory for testing.

Hollow-stem auger “refusal” to further penetration (i.e., slow penetration rate) was encountered at B-2 and B-3 at 48.5 and 44 feet bgs, respectively. Bedrock coring was not performed to confirm the refusal surface as bedrock. However, considering that proximate borings B-1, B-4, and B-5 were advanced to depths of 52 to 72 feet bgs without refusal, it is not believed that bedrock was encountered at B-2 or B-3.

Upon completion of drilling, each boring was tremie-grouted to ground surface with cement-based grout. A detailed record of the drilling, testing, and sampling performed is provided on the Geotechnical Boring Records presented in Attachment 1.

ATC Associates of Novi, Michigan performed geotechnical laboratory testing of representative soil samples selected from the geotechnical borings by Wood. The following tests were performed:

• Moisture content determinations (ASTM D 2216)

• Atterberg limits tests (ASTM 4318)

• Particle-size analyses - washed sieve only (ASTM D 6913)

• Unconsolidated Undrained (UU) triaxial tests (ASTM D 2850)

• Direct Shear (ASTM D 3080)

• Laboratory vane shear

• Bulk Density

Geotechnical laboratory testing was performed in general accordance with the referenced ASTM standards. A summary of the laboratory testing results is included in Attachment 2. Individual test reports are also provided in Attachment 2.

SUBSURFACE CONDITIONS

Topsoil or asphalt pavement was encountered at ground surface at each boring locations.

Beneath the topsoil and pavement, overburden soils consist of stratified, alternating layers of Sand and Silt/Clay. Table 1 summarizes the stratigraphy encountered and/or interpreted at each boring location.

Sand - - - - 45.0 – 52.0

Asphalt pavement was encountered at ground surface at B-2, B-3, and B-4 and is approximately 6-inches thick.

Topsoil was encountered at ground surface at B-1 and B-5. Where encountered the topsoil is approximately 1.5 feet thick and consists of moist, brown silty sand with organics. The topsoil is visually classified as SM soil in accordance with the Unified Soil Classification System (USCS) and described as very loose to loose relative density based on SPT N-values of 4 blows per foot (bpf).

The Sand strata generally consists of brown to gray sand, sand with silt, or silty sand with a lesser, varying amount of gravel. Occasional gravel/cobble seams were also encountered. The Sand is classified as SP, SP-SM, or SM soil in accordance with the USCS. SPT N-values generally range from 7 to 10 bpf between 0 and 5 feet bgs, indicating loose to medium dense relative density. SPT N-values at depths greater than 5 feet bgs in the Sand strata range from approximately 17 to greater than 50 bpf, indicating medium dense to very dense relative density. The Sand is typically described as moist above the groundwater table and wet/saturated below the groundwater table. Particle-size analyses indicate the Sand consists of 2.2 to 14.2 percent gravel, 75.2 to 84.4 percent sand, and 7.4 to 13.4 percent fines (i.e., silt and clay sized particles) based on three laboratory tests. Direct shear results indicate the peak effective friction angle (’) of the Sand ranges from 33.3 to 39.9 degrees, based on four tests.

The Silt/Clay strata generally consists of gray sandy silt, silt, clay, or silty clay with a lesser, varying amount of sand. Occasional gravel/cobbles were also encountered within the Silt/Clay.

The Silt/Clay is classified as ML, CL, or CL-ML soil in accordance with the USCS. SPT N-values generally range from 5 to greater than 30 bpf indicating medium stiff to hard consistency. The Silt/Clay is typically described as moist to wet. The moisture content of the Silt/Clay ranges from

18.2 to 28.9, based on 12 tests. The liquid limit ranges from 20 to 38, the plastic limit ranges from 13 to 20, and the plasticity index ranges from 7 to 19, based on 11 tests. Two particle-size analyses indicate the Silt/Clay consists 0.0 percent gravel, 8.6 to 39.5 percent sand, and 60.5 to

91.4 percent fines. Results of four UU triaxial tests indicate peak undrained shear strength (su) of the Silt/Clay ranges from 1800 to 2232 pounds per square foot (psf).

Bedrock was not encountered and/or interpreted at any of the boring locations.

Groundwater is interpreted between 10 to 20 feet bgs at B-1 through B-4 based on observed moisture of split-spoon and Shelby tube samples. At B-5, wet soils are noted at shallower depth, approximately 2 feet bgs. Site groundwater levels will fluctuate in response to precipitation events, seasonal conditions, construction activity, site use/activity, and adjacent site use/activity, and may therefore vary from those presented herein.

CLOSING

The findings presented herein were prepared in accordance with generally accepted geotechnical engineering principles and professional engineering practice, consistent with the level of care and skill ordinarily exercised by members of the profession currently practicing in the same locality under similar conditions. We make no other warranty, either expressed or implied. The findings presented herein are based on the results of the geotechnical explorations and laboratory testing, combined with interpretation and interpolation of soil and groundwater conditions between and beyond the widely spaced explorations. Important information from the Geoprofessional Business Association (GBA) regarding the limitations of this Technical Memorandum is provided in Attachment 3.
