Project and Contracting Success

We have met the remedial goals on 100% of our ERH remediation projects and surpassed them on several Guaranteed Fixed Price Remediation (GFPR) projects, several by orders of magnitude including -

• Glendive, MT – In January 2007, TRS achieved an average 99.5% reduction of TCE in soil. Ninety three percent of the confirmatory soil samples were non-detect. The contracted remedial goal was to reduce TCE concentrations in soil to 0.1 mg/kg for a 99% reduction. The begriming TCE concentration in soil was 85 mg/kg. (more information - PDF)
• Queens, NY – In 2006, TRS achieved greater than 99.999% average reduction of PCE in soil. Twenty-four of 25 confirmatory soil samples were non-detect for PCE in just five months of ERH operations. (more information - PDF)
• Olney, IL – In 2004, TRS achieved greater than 99.999% average reduction of TCE in soil following 59 days of ERH operations. This was a GFPR based on project completion within 20 weeks from notice to proceed (NTP), a numerical goal for TCE in soil and $5,000 per day in liquidated damages for each day of operations beyond 20 weeks. TRS completed the project within the 20 weeks of NTP. The original remedial goal was based on an 82% average reduction of TCE in soil. (more information - PDF)
• Springfield, MO – In 2005, TRS achieved an average 99.96% reduction of TCE in soil and 99.9% reduction of TCE in groundwater in four months of operations. The remedial goal was based on reducing the 90% UCL for TCE in soil to 0.4 mg/kg, a reduction of about 99%. The beginning average TCE concentrations were 325 mg/kg in soil and 8,400 μg/l in groundwater. The final average TCE concentrations were 0.119 mg/kg in soil and 10 ug/l in groundwater.

• Great Lakes, IL – In 2006, TRS achieved a greater than 99% average reduction in PCE concentrations in soil in just over four months of ERH operations. The remedial goal was based on reducing PCE concentrations by 95.5%. The contract for this project was based on Pay for Performance and a guaranteed fixed price. (more information - PDF)
• Paducah, KY– In 2003, TRS achieved an average 99% and 98% reductions of TCE in soil and groundwater and recovered more than 30,000 lbs TCE mass during five months of ERH operations. The goal was an average 75% reduction in TCE in soil and groundwater. (more information - PDF)
• Annapolis, MD – In 2006, a couple of months into operations, the interim soil-sampling event was non-detect. TRS achieved a 99.9% average reduction of 1,1,2,2 – tetrachloroethane (TeCA) in soil following four months of ERH operations. The contracted remedial goal was an average 95% reduction of TeCA in soil. The final confirmatory soil sample results, collected on 2/15/07 approximately one year following the interim sampling event, also showed an average 99.9% reduction in total CVOCs in soil.

• Chicago, IL – In 2006, TRS achieved 170 mg/kg of PCE and 1000 mg/kg of TCE in soil following four months of ERH operations using sheet pile electrodes. The remedial goal was 240 mg/kg PCE and 1,300 mg/kg TCE in soil. (more information - PDF)
• Ft. Wayne, IN – In 2004, TRS achieved a 93% reduction in TCE mass following four months of operations. The goal was a 90% reduction in TCE mass. (more information - PDF)
• Downers Grove, IL – In 2005, TRS achieved a greater than 99% reduction of TCE in soil. The goal was based on reducing the 95% UCL for TCE in soil. The beginning average TCE concentration in soil was 137 mg/kg, respectively. The final average TCE concentration in soil was 0.559 mg/kg.
• Chicago, IL – In 2002, TRS achieved a 99% average reduction in PCE in soil following 120 days of ERH operations. The goal was an average 90% reduction. (more information - PDF)
