Manufacturer's claims: BG-BioEnchancer 850 is a blend of organic and inorganic nutrients. It accelerates the natural biodegradation of organics, including crude oils, fuels, and chemicals. Besides the basic 850 supplement, the company has more specialized 8501, 8502, and 8503 supplements. The company makes no claims of success for their product in Alaska and advises a test plot before full-scale use. They are willing to send a small sample for testing. They want you to call them and discuss your specific needs before they recommend a specific product.

Site maintenance intensity: Routine monitoring.

Mobility: Shipped as a granular power. Mix it onsite with water and apply it with a sprayer or mix it in as powder. No special personal protective equipment is required.

Cold climate applicability: These products are nutrients for microbes. The limitations are those of the microbes, not the nutrients. Microbes are active at temperatures of 50 °F or above. They don't really work at temperatures below 40 to 45 °F.

Approximate cost to treat a cubic yard: Granular powder runs from $7.24 to $28.43 per pound. 2.33 pounds of powder makes 5 gallons of liquid concentrate. 1 gallon treats 40,000 parts per million of contaminants in 1 cubic yard of soil. Never use less than 1/4 pound of powder to treat 1 cubic yard.

Manufacturer's comments: Microbes don't work well when contaminant level is above 5,000 parts per million. At contamination levels higher than 10,000 parts per million, the manufacturer does not advise using microbes.

Formal research: Inhouse studies. Contact the company for this information.

Field users' contacts: Contact the manufacturer with your specific site conditions to get appropriate references. Their Web site shows some successful case studies. One case study was at the Quantico Marine Base in Virginia.

Product name: BioLuxing

Product category: Delivery system

Manufacturer's claims: BioLuxing enhances and stimulates the growth of biodegradative activity of microorganisms by adding pathways and attachment surfaces for nutrients, oxygen, and other stimulants to the site. This process is completed within a BioNet. A BioNet consists of a series of BioLux fractures. A BioLux is installed by drilling and inserting steel casings to a desired depth and injecting a fluid containing a porous ceramic propellant, Isolite. The injection process causes fractures to open, which are maintained by the Isolite. This also establishes a gallery from which the microorganisms preinoculated in the Isolite can biodegrade contaminants in the vicinity of the BioLux. The steel casing can be used to inject additional microorganisms, moisture, oxygen, or to apply a vacuum (for vapor extraction). The system is effective in tight, low porosity soils. The Isolite-reinforced fractures also increase the rate of conductivity through the subsurface.

Site maintenance intensity: Low maintenance if conditions are met at the layer where the BioLuxes are installed. Monitoring and maintenance may be required for a 2- to 3-year period.

Mobility: Must be accessible by semitruck (for Isolite delivery).

Cold climate applicability: Installation of BioLuxes is hampered when the ambient temperature is below 30 °F. Temperature does not affect the process after it has been installed. Temperature limits still apply to biodegradation.

Approximate cost to treat a cubic yard: $40 to $60

Manufacturer's comments: The product works very well in tight, low-porosity soils such as clays and glacial till. Fractures may not be possible in coarse-grain soils. It may be installed as deep as 50 feet with little aboveground disturbance. It may not be cost effective for very small volumes of contamination.

Product name: BioSolve

Product category: Surfactant

Manufacturer information:

Manufacturer's claims: BioSolve is a biodegradable, liquid surfactant formulation that can be used as a stand-alone technology or as an amendment to existing processes, such as pump and treat systems, extraction processes, and others. BioSolve liberates the free-phase organic contaminant from the matrix (soil) by increasing the contaminant's solubility and encapsulating it in a micellular emulsion. BioSolve also reduces interfacial tensions between the contaminants and the matrix, increasing extraction potential. In other words, BioSolve desorbs the contaminants from the soil's particles, allowing easier access by microorganisms or increasing recovery potential.

Site maintenance intensity: Depends on the remediation technology.

Mobility: This liquid is safe to repackage.

Cold climate applicability: Works well in the cold.

Approximate cost to treat a cubic yard: None given.

Manufacturer's comments: BioSolve is designed to mobilize contaminants so the potential exists for unwanted pollution migration unless the proper steps are taken for hydraulic control. Sensitive areas such as wetlands should be taken into consideration.

Product name: DARAMEND

Product category: Nutrient supplement

Manufacturer's claims: A matrix-specific solid-phase organic amendment used to alter sediment structure, nutrient profile, and water-holding capacity. Amendments serve to increase water and nutrient availability and provide a surface where microorganisms and contaminants can interact.

Site maintenance intensity: Depends on application technology.

Mobility: Available in a variety of forms and containers.

Cold climate applicability: Cold temperatures will not affect the product itself, but it will affect the bioremediation process.

Approximate cost to treat a cubic yard: Not applicable.
