Remove The Tea Bag Without Removing The Building

When a source of ground water contamination or contaminant vapors is present under a building, efforts to mitigate the spread of contamination may continue indefinitely with mounting costs.  Bioremediation may be used to remove the source of vapors or ground water contamination without damage to the building or interrupting operations.

There are many examples of this approach in the case studies on this site.  You can call us to find whether this approach is applicable to your site and the potential cost savings.

Multiple Contaminant Bioremediation

/in , , , , , , , , , /by

Cl Solutions provides special microbial blends for the bioremediation of different contaminant types.  However, the advantage of the Pseudomonas sp. in our products is that they have multiple metabolic capabilities, which means for example that a blend optimized for cometabolism of chlorinated solvents can also be effective in petroleum removal.

A recent study by a user of our products showed that the CL Solutions’ patented approach for 1,4-dioxane bioremediation can also degrade a range of chlorinated volatile organic compounds (CVOCs).

Other examples of the successful treatment of mixed plumes are:

Petrox removal of petroleum compounds and trace levels of chlorinated solvents.

Petrox cometabolism of MTBE using petroleum components as a substrate and removing them simultaneously.

CL-Out simultaneous removal of nitrates and perchlorate.

Feel free to check out the case studies or call us for more information.

 

 

Fast Bioremediation Eases Site Development in Boston

/in , , , , , , , , /by

Underground storage tank (UST) leaks from a former gas station contaminated shallow ground water under a parking lot for a commercial building.  The UST contamination was found during trenching for utilities.  As the presence of contamination prevented further property development, fast remediation was important to the stakeholders.

The size of ground water plume that resulted from leaching soil contaminants was estimated to be 5,000 square feet.    The contamination was mainly diesel-range petroleum constituents, with the highest concentrations in the aliphatic range, but there were also scattered detections of xylene, toluene, and ethylbenzene.

Petrox bioremediation was implemented in the ground water.  Three units of Petrox (165 gallons) were injected into the contaminated ground water through vertical injection wells located up gradient of the monitoring wells.

After a single inoculation of Petrox, the contaminant concentrations were reduced across the property.  The following table shows the overall reduction in both the volatile and semi-volatile range hydrocarbons.

Patent Granted for Perchlorate Bioremediation

The US Patent Office has granted a patent for bioremediation of perchlorate in contaminated media to Michael Saul of CL Solutions and Andrew Irwin of Irwin Engineers of Natick, Massachusetts. This patent is based on the application of bioremediation to remediate perchlorate contaminated soil, sediments and ground water at a site in Massachusetts.  CL Solutions and Irwin Engineers collaborated on the the remediation of the site, where the perchlorate concentrations were reduced by orders of magnitude in one year of active treatment.  The project is a featured case study elsewhere on this site.

 

Fast, Easy Drainage Ditch Cleanup

Petrox bioremediation of surface spills and TPH accumulation in drainage ditches and maintenance areas is simple. Using a simple manual sprayer, the Petrox is applied to the soil surface. The Petrox microbes begin bioremediation immediately to enhance natural digestion of the petroleum, like probiotics for petroleum destruction.  Unlike detergents that wash the visible oil deeper in the soil, Petrox microbes destroy the all of the oil.

The following chart and table show the results of the application of Petrox to petroleum-contaminated soil in a drainage ditch. After about 60 days, the TPH concentration was reduced by 67% in one location and over 90% in three locations.  A second application to the 30 ft. north area reduced the concentration even more.

The problem was solved for a total Petrox cost of $600.
