Treatability Studies

SiREM maintains a state-of-the-art treatability laboratory equipped with the instrumentation and staff to conduct high quality treatability studies to evaluate bioremediation, chemical oxidation, and zero valent iron based technologies to treat chlorinated solvents, perchlorate and many other recalcitrant compounds. The studies are used to predict full-scale remediation performance and to assess and optimize remediation strategies under simulated site conditions to enhance system performance. SiREM provides laboratory treatability testing services include:

• Assessment of Enhanced In-Situ Bioremediation (EISB)

• Assessment of Monitored Natural Attenuation (MNA) Sustainability

• Evaluation of Abiotic Degradation Approaches

Molecular Genetic Testing

The presence and concentration of Dehalococcoides and Dehalobacter microorganisms is critical to success in bioremediation of chlorinated solvents. Gene-Trac® quantitative polymerase chain reaction (PCR) testing is used to quantify and characterize these key dechlorinating bacteria in groundwater samples from contaminated sites.

• SiREM is a leader in the field of molecular genetic testing relating to biodegradation of chlorinated solvents. SiREM was the first commercial laboratory to offer Dehalococcoides testing under our Gene-Trac banner and is once again leading the field by providing functional gene analysis for vinyl chloride reductase with our Gene-Trac-VC test. SiREM has close working relationships/intellectual property agreements with academic and industry partners including DuPont* and Stanford University**, keeping SiREM at the forefront of this dynamic field and providing first-rate analysis and technical support to our customers.

Gene-Trac testing is offered through exclusive license agreements with: *Du Pont de Nemours & Co. (United States Patent, US6894156B2 [Hendrickson and Ebersole]); and **Stanford University (United States Patent Application USSN 60/598459 [Spormann and McCarty])

• Laboratory Matrix Oxidant Demand Tests: If refined measurements of oxidant demand are required for design /implementation of In situ chemical oxidation (ISCO) remedies then look to SiREM to provide high quality results in a timely manner.

• ISCO Treatability Studies: SiREM, an industry leader in the area of treatability studies, can confirm the breakdown of contaminants by replicating site conditions in a laboratory chemical oxidation treatability study and answer the following questions.

Remediation Technologies

SiREM produces innovative, in-situ, remedial technologies available and approved for use in Canada

• KB-1® Bioaugmentation: SiREM produces the KB-1® bioaugmentation culture used for sites where beneficial dechlorinating Dehalococcoides microorganisms are absent, present at low concentrations, or are the wrong strain required for the complete biodegradation of chlorinated solvents (e.g., trichloroethene [TCE]). KB-1® is the most widely used Dehalococcoides bioaugmentation culture in the world and has been applied at sites in North America and Europe. KB-1® is the only culture of its type approved for groundwater remediation in Canada through the New Substances Notification Regulation of the Environmental Protection Act.

• KB-1® Plus is a suite of custom-blended microbial culture formulations for bioaugmentation of sites with inhibitory concentrations of chlorinated ethanes and chlorinated methanes, which are often comingled with chlorinated ethenes.

• Self Sustaining Treatment for Active Remediation (STAR): STAR is a new and innovative technology to remediate Non-Aqueous Phase Liquids (NAPLs). It uses smoldering combustion – the type of combustion that turns charcoal into ash in your barbeque grill – to quickly and efficiently destroy contaminants. http://star.siremlab.com/
