TSIC™ Culture-- TS Innoculum for Chlorinated Compounds  is a natural enriched bacteria culture that contains species of  Dehalcoccoides  for bioaugmentation.  This non-methanogenic culture dechlorinates PCE to the non-toxic product ethene.  It can be used at sites where bacteria capable of complete reductive dechlorination are not present or there is a need to decrease the remediation time frame.  Although antidotal, it has been estimated that the causative microorganism Dehalococcoides is not present in 10 to 40 percent of chlorinated solvent contaminated sites.

Reduces treatment time requirement for complete dechlorination -

Proven effectiveness -

SRS™ -- Slow Release Substrate is a patented engineered product for the reductive dechlorination of chlorinated solvents (e.g., PCE, TCE, cis-DCE, TCA, and 1,2 DCA) or any anaerobically degradable substance (perchlorate, TNT, RDX, etc.).  The substrate package is a low viscosity liquid that contains a combination of slow and fast release electron donors and required nutrients.  SRS™ is a vegetable oil based substrate package that is used by naturally occurring microorganisms as an energy and carbon source to reductively dechlorinate solvents. 

As a result of its low viscosity and longevity, SRS™ is an ideal substrate for injection using direct-push technology.  The low viscosity allows a greater volume of SRS™ to be applied in a shorter period of time and increases the substrate delivery radius per point. This results in fewer injection points and overall shorter delivery time requirements per site.  It can also be injected into the subsurface through injection wells.

SRS™ is designed to release bio-available hydrogen over a period of 3 to 5 years thus enhancing the long-term anaerobic biodegradation of the chlorinated solvents.  SRS™ optimizes the naturally occurring biodegradation system by supplying the rate limiting factor (in this case hydrogen) in the degradation of VOC’s, certain pesticides/herbicides and immobilization of certain metals (Cr and As). 

Key Benefits of SRS^TM & Its Slow Release Formula

Degrades PCE and TCE to non-toxic end products - SRS™ provides an environmentally acceptable environment for the bacteria to rapidly and completely dechlorinate PCE and TCE to non-toxic end products such as ethene or ethane. 

Low cost - The passive nature of the SRS^TM Technology eliminates the large capital and operations/maintenance costs associated with active engineered systems such as pump and treat, air sparging with vapor extraction and continuous recirculation systems.  Savings can be as high as 90% when compared to a pump and treat system on a net present cost basis.  At a number of sites, SRS^TM will be less expensive than Monitored Natural Attenuation (MNA).

Slow release eliminates continuous substrate additions - Since the SRS^TM material degrades over a long period of time, SRS^TM significantly reduces O&M costs compared to the repeated or continuous injections required for soluble substrates such as lactate or molasses.

Non-toxic food grade materials - SRS^TM is made with food grade materials that have Generally Recognized As Safe (GRAS) status.  It can be injected directly into the aquifer through push-points or wells.

Cuts off plume migration - SRS^TM can be applied in a barrier configuration to avoid further plume migration.  This configuration is a fraction of the cost of other permeable reactive barriers and can be applied in deeper aquifers.
