Tucker, Young, Jackson, Tull, Inc. (TYJT) is a subconsultant to CH2M HILL on the U.S. EPA Region 5, Response Action Contract (RAC). As a minority firm, TYJT is part of the Mentor Protégé relationship with CH2M HILL, a national firm. This RAC provides professional architect/ engineer, technical and management services to the Environmental Protection Agency (EPA) to support remedial response, enforcement oversight and non-time critical removal activities in Region 5, under the Comprehensive Environmental Response Compensation and Liability Act of 1980 (CERCLA), as amended by the Superfund Amendments and Reauthorization Act of 1986 (SARA).

TYJT entered into a Protégé relationship with the USEPA and CH2M Hill, Inc. to provide resident engineering services to SuperFund projects within USEPA Region V area. The remedial actions at the LEC site commenced in April 1998. As an USEPA representative on the site, TYJT responsibilities have included: complete project management, health and safety monitoring, sample collection and data analysis, subcontractor management, maintenance of public safety and relations, and final report preparation.

The subject site was located near a residential neighborhood in the City of Wyandotte along the Lower Ecorse River . Prior to the residential developments in the 1930's, this low-lying area had been backfilled with soils contaminated with Ferro Ferric Cyanide ( a byproduct of coal gas generation) - distinctive blue green colored soils. The maximum concentration of cyanide in the soil was as high as 100 g/kg (10%). The presence of cyanide was first discovered in 1987, due to the deterioration of basement walls and the seepage of blue colored water.

Following an extensive hydrogeologic investigation conducted by the USEPA and their consultant, CH2M Hill, Inc. other contaminants were discovered. These have included Polynuclear Aeromatics (PNAs), Arsenic, Manganese, and Lead. The contaminants were found at 44 individual locations distributed along the mile long residential area. A feasibility analysis indicated that the best method of remediation was AExcavation and disposal at licensed facility as Hazardous Waste.

Approximately 2,000 cubic yards of impacted soils above the residential cleanup criteria has been removed and disposed. In addition, 70,000 gallons of impacted water has been removed. A total of 400 soil samples were collected and analyzed during the remedial action. The site meets the USEPA and MDEQ requirements and is ready for closure. The total cost of Remedial Action is $600,000.

In addition, TYJT has provided planning and oversight activities for sites in Michigan; these include the following:
