Treatment of Petroleum-Contaminated Soils
Product name: HLR-80
Product category: Microbial cultures
Manufacturer information:
NatRx, Inc.
P.O. Box 735
Muleshoe, TX 79347
Phone: 877–628–7948
Fax: 806–272–5537
Manufacturer's claims: Noticeable remedial activity will occur within 30 to 60 days. HLR-80 has been tested at remote Forest Service sites in Alaska as a surface application under the direction of North Pacific Technology. HLR-80 contains an aggressive strain of hydrocarbon-consuming bacteria coupled with a dissolved oxygen catalyst. This stimulates the introduced and indigenous bacteria by increasing the available dissolved oxygen and energy needed for rapid bioremediation.
Site maintenance intensity: Depends on the application technique used.
Mobility: Any container that holds liquids can be used for transportation.
Cold climate applicability: Field test results indicate HLR-80 may require other technologies such as biopiles to overcome the effects of cold temperatures on the rate of degradation.
Approximate cost to treat a cubic yard: $35.28 to $39.81 per gallon.
Manufacturer's comments: The oxygen supplement (TRX-90) is available separately.

Manufacturer's claims: Humasol is composed of about 85 percent humic substances including: 55 percent fulvic acid and 30 percent remaining 15 percent includes natural minerals and nitrogen. Humasol enhances soil microbes, especially fungi that use lignin to break down hydrocarbon chemicals for a food source. The manufacturer claims that Humasol binds with heavy metals.
Site maintenance intensity: None, if used as an indigenous microbial supplement. Apply it and water. Otherwise, site maintenance intensity depends on the application technique used.
Mobility: Sold in 50-pound or 1-ton bags. It is also available in liquid and granular form. Humasol can be repackaged.
Cold climate applicability: The product is used as a nutrient supplement for soil microorganisms. Cold temperatures will not affect Humasol itself, but they will affect the remediation process.
Approximate cost to treat a cubic yard: Less than $1 per cubic yard.
Manufacturer's comments: Humasol can also be used as a fertilizer substitute to enhance plant growth.
Formal research: None to date, but Dr. Suzanne Lesafe of the Canadian National Water Resource Institute has published information on the use of humate substances in petrochemical bioremediation.

Manufacturer's claims: The microbial culture contains specifically selected hydrocarbon and xenobiotic chemical-degrading microorganisms. The liquid-based product comes ready to use. Microbial nutrient packages are also available. These products increase the rate of degradation of the target compounds.
Site maintenance intensity: Normal remediation application maintenance. Micro-Bac recommends monthly monitoring.
Mobility: Liquid form. The product comes in 1-, 5-, and 55-gallon containers.
Cold climate applicability: The M-1000 product line requires liquid water for activity. Freezing will cause a loss of about 50 percent of the microorganisms. Those remaining will continue to function after being thawed. An antifreeze-protected version is available. Product functions best in the range of 10 to 40 °C.
Approximate cost to treat a cubic yard: Less than $10.
Manufacturer's comments: Company is a minority-owned small business.
Formal research: None available.
Field users' contacts: Contact company for references.

Manufacturer's claims: Several strains of microbes work synergistically to clean up hydrocarbon-based and organic contamination, such as: diesel, gasoline, glycols, benzene, aviation fuel, hydraulic and motor oils, latrine and septic wastes, and AFFF (aqueous film-forming foams) fire waste. Works aerobically or anaerobically. Micro-Blaze is composed of spore-forming bacteria that can revert to a spore state if conditions become unviable. They will germinate after the correct conditions return.
Site maintenance intensity: Depends on the remediation technique used. It is important to keep the site moist.
Mobility: Concentrated product ships in 5-, 55-, or 250-gallon containers-simply dilute and apply.
Cold climate applicability: Micro-Blaze microbes work best within a temperature range of 60 to 85 °F. Temperature endpoints for remediation are about 35 to 120 °F. Micro-Blaze is composed of spore-forming bacteria that can revert to a spore state if conditions become unviable. They will germinate after the correct conditions return. They will work within a wide pH range of 4.0 to 10.5 and can tolerate temperatures up to 200 °F for a short period.
Approximate cost to treat a cubic yard: $1.90 to $2.60 per cubic yard. &guot;Rule of thumb" is 1 gallon of concentrate for every 10 cubic yards of contaminant.
Manufacturer's comments: When in concentrated form, the product has an indefinite shelf life. When the product is diluted to 3 percent, the shelf life is several years. The same bottle of Micro-Blaze can be used to control odors at restrooms and to clean up gas and oil spills. Verde, Inc., also offers a nontoxic biodegradable firefighting foam design to degrade hydrocarbon contaminants. See Micro-Blaze's Web site for more information.
Formal research: In progress as of November 19, 1999.
Field users' contacts: Please contact the manufacturer for cases relating to your applications.
