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 was the visible oil away, 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.

Safer Choice Bioremediator for Dry Cleaners

CL-Out has been honored to have the US EPA Safer Choice designation (formerly Design for the Environment) since 2003. This designation signifies Cl-Out is safer for human health and the environment than other remediation products.

CL-Out has been used for the remediation of hundreds of  contaminated sites across the US.  It is also a lower cost alternative.  CL-Out provides a safer and economical alternative with out sacrificing quality and effectiveness.  For more information or free consultation call CL Solutions at 513-284-5940.

CL-Out Manufacturer Named USEPA Safer Choice Partner of the Year

Osprey Biotechnics is being recognized as an outstanding Safer Choice Formulator-Manufacturer (as well as a noteworthy Innovator). Osprey Biotechnics develops microbial products and bioproducts for a large range of environmental, industrial, and agricultural applications, including consumer products. Safer Choice commends Osprey’s various achievements, including continuing to increase its offering of Safer Choice-labeled products and sales since they first became a partner in 2003. Osprey Biotechnics uses microorganisms as alternatives to traditional chemicals and prominently uses the Safer Choice label on all products. Also, the company emphasizes water recycling, safer chemical substitution, and soil and animal health in its manufacturing processes.

Bioremediation of Industrial Fill

Historical industrial sites often have deposits of fill material containing a wide range of organic contaminants.   Perched ground water  present in the base of the fill is usually impacted by the contaminants and may provide a mechanism for off-property migration of the contaminants.  The organic contaminants are wide spread throughout the fill without a well defined source area.  Cost-effective remediation is difficult with this combination of conditions.

Bioaugmentation with CL-Out or Petrox can remove the contaminants from the fill and perched water by destruction in place.  The organisms in CL-Out and Petrox can metabolize a wide-range of organic chemicals at concentrations from separate-phase layers to part per trillion levels.  Soil and ground water contaminants are addressed simultaneously though injection of the microbes without disturbing the  site operations.

The following table shows typical results from a single application of Petrox to contaminated soil and perched ground water on July 10, 2011.  The remediation progress was tracked by ground water monitoring because it was the easiest sampling method once wells were in place.Industrial Fill TreatmentThe results show that within 30 days the contaminant concentrations in perched water were reduced by 50%.  After 60 days there was slight rebound in come of the contaminants, showing that more soil treatment may be necessary if lower cleanup goals needed to be maintained.

 

 

Vermont Dry Cleaner Remediation Using CL-Out

Cl-Out bioremediation was used to remove PCE from ground water at a dry cleaners in Vermont.  CL-Out micorbes were selected for bioremediation of the site because they are compatible with the natural aerobic aquifer conditions.  One application of CL-Out bioaugmentation reduced the PCE concentration by 90% in less than 6 months without increasing the vinyl chloride concentrations.

The following table summarizes the process of aerobic cometabolism of PCE.  The pre-bioaugmentation sampling showed aerobic conditions and a low population of Pseudomonas microbes.  After bioaugmentation the Pseudomonas population was higher.  As the microbes consumed the dextrose substrate and produced the oxygenase enzymes necessary for PCE destruction, the ORP and PCE concentrations decreased.  Six months after the bioaugmentation, the microbial population returned to the pre-bioaugmentation conditions.
