Soil Boring and Temporary Well Installation, and Monitoring Well Abandonment, Sleeping Bear Dunes National Lakeshore (SBDU), North Manitou Island, Michigan
TTL installed soil borings, installed temporary wells and abandoned existing monitoring wells using direct-push technology and hollow stem augering methods at the SBDU North Manitou Island site. The work was completed utilizing all-terrain rigs, Geoprobe®, and a two-person drilling crew for each to complete the boring operations as requested. Access to the remote area was by barge and all supplies, lodging, meals, and fuel had to be mobilized in one barge mobilization due to the remoteness of the area.
Expansion of Groundwater Pump and Treat System, Former Wurtsmith Air Force Base, Michigan
TTL has over eight years of experience working at Wurtsmith AFB including four Indefinite Delivery/Indefinite Quantity (IDIQ) cost reimbursable Task Orders (TOs) in the last five years in support of the final remedy for landfills 30/31 to prevent the migration of landfill leachate.

Asbestos Abatement, Hazardous Material Removal & Radiological Decontamination, NASA Plum Brook Station
This T&M project involved the removal of asbestos containing materials and demolition of multiple structures associated with the Reactor Facility. TTL/TolTest personnel removed in excess of 5,000LF of thermal insulation, over 5,000SF of boiler, and 1,000SF of tank insulation as well as the removal and packaging of PCB containing waste, lead containing materials, and radiological decontamination.
Environmental Remediation Services, Monroe Bank and Trust, Monroe, Michigan
During the site redevelopment for a commercial bank, petroleum chlorinated compound contaminated soil was detected in excess of soil saturation concentrations and State of Michigan criteria. TTL was contracted to characterize the nature and extent of the releases. The results of the site investigation were used to prepare a Remedial Investigation Report and an Interim Response Plan (RIR/IRP).
Preliminary Phase II Site Assessment, Swan Creek Revitalization Area, Toledo, Ohio
Under a contract with the City of Toledo, TTL conducted a subsurface investigation of an area within the Swan Creek Watershed targeted for economic redevelopment called the Swan Creek Revitalization Area (SCRA). The investigation included an evaluation of soil, groundwater and sediment in and along the SCRA for impact from its historical industrial use, as well as the advancement of 32 soil borings, collection of 17 bank samples, collection of 28 sediment samples from Swan Creek, and installation of 8 monitoring wells.
EPA Brownfield Grant Management & Implementation, Various Sites, Southeast Michigan
The Downriver Area Brownfield Consortium is an effort of six communities in the downriver area of Wayne County to develop, test, and implement a program to redevelop ‘brownfield’ properties. The program was first developed as part of a successful 1996 application for funding from the U.S. Environmental Protection Agency (USEPA) Brownfield Pilot grant competition. Its core model has four elements: site identification, site assessment, due care planning, and site marketing.
Geotechnical Engineering and Environmental Services, Toledo Waterways Initiative
TTL completed numerous geotechnical subsurface investigations for multiple projects including installation of sewers using open-cut, bore-and-jack, and pilot tube micro-tunneling methods, installation of major underground CSO storage basins and pump stations, as well as design and construction of associated roadway pavements.
