Treatment of Petroleum-Contaminated Soils
Product name: Alken Bio-Nutrient 4
Product category: Nutrient supplement
Manufacturer information:
Valerie Edwards
Alken-Murray Corp.
P.O. Box 400
New Hyde Park, NY 11040
Phone: 540–636–1236
Fax: 718–224–0754

Manufacturer's claims: Alken Bio-Nutrient 4 is a soluble, dry, rapidly-absorbed nutrient supplement to enhance bacterial metabolism of petroleum-contaminated soil. The product contains urea, potassium, and micronutrients, including dicyandiamide. Dicyandiamide inhibits nitrification of ammonia to nitrate. Ammonia ions will be retained in the remediation zone, while negatively charged nitrate can be removed by groundwater flow through anoxic respiration (in the absence of oxygen), producing inert nitrogen gas.
Site maintenance intensity: Depends on the application technique used.
Mobility: The product comes in 25-, 50-, and 500-pound containers. Repackaging is safe.
Cold climate applicability: Bio-Nutrient 4 is not affected by freezing. The product can be used from 35 to 180 °F. If temperatures fall below 35 °F, the product will not be active, but it will reactivate when the temperature rises above 35 °F.
Approximate cost to treat a cubic yard: 50 cents to $2, depending on nutrient deficiencies.
Manufacturer's comments: Product bulletin, material safety data sheets, dosage charts, and other information are available on Alken-Murray's Web site.
Formal research: None to date, new product.
Field users' contacts: None to date, new product.
Product name: Alken Clear-Flo 7026
Product category: Microbial cultures
Manufacturer information:

Manufacturer's claims: Alken Clear-Flo is Alken-Murray's most popular hydrocarbon-degrading formula. It remediates a wide variety of hydrocarbons such as phenol, various solvents, and sulfur-containing components, alcohols, chlorinated hydro-carbons, polynuclear aromatics, and other difficult compounds.
Site maintenance intensity: Depends on the application technique used.
Mobility: Product comes in 25-, 50-, and 500-pound containers. Repackaging is safe.
Cold climate applicability: Product is effective from 42 to 110 °F with pH range from 5.9 to 9.0. Optimal temperature is 75 °F +/- 10 °F. Optimal pH is 7.1 +/- 0.3. Product is guaranteed for a 2-year shelf life. Containers stored more than 2 years should have holes punched in them to allow air to circulate. Freezing will reduce the reactivation rate, but will not kill the product.
Approximate cost to treat a cubic yard: $17 to $20 if a preacclimation device is used to recycle the runoff.
Manufacturer's comments: Guaranteed shelf life of 2 years. A free sample is available for bench testing.

Manufacturer's claims: Alken Clear-Flo 7036 contains 21 strains of hydrocarbon-degrading microbes designed to degrade heavy and light distilled oil fractions, including crude oil and coal tar.
Site maintenance intensity: Depends on the application technique used.
Mobility: Product comes in 25-, 50-, and 500-pound containers. Repackaging is safe.
Cold climate applicability: Product is most effective from 40 to 100 °F with pH range from 6.0 to 8.5. Freezing will reduce the reactivation rate, but will not kill the product. Prolonged high temperatures could harm the product.
Approximate cost to treat a cubic yard: $17 to $20 depending on application technique.
Manufacturer's comments: Guaranteed shelf life of 2 years. A free sample is available for bench testing.

Product name: Alken Enz-Odor
Product category: Nutrient supplement
Manufacturer information:
Valerie Edwards
Alken-Murray Corp.
P.O. Box 400
New Hyde Park, NY 11040
Phone: 540–636–1236
Fax: 718–224–0754
Web site: http://www.alken-murray.com
Manufacturer's claims: Alken Enz-Odor is a blend of a surfactant, four strains of humic acid, humin, lignin, and other organic matter. The bacteria and humic extracts that emulsify the oil-water barrier give the bacteria easier access to the oil. The synergistic blend of this formula makes the product much more powerful than its individual components.
Site maintenance intensity: Depends on the application technique used.
Mobility: Product comes in 25-, 50-, and 500-pound containers. Repackaging is safe.
Cold climate applicability: The product is most effective from 49 to 115 °F. and pH range from 6.0 to 8.5. Freezing will seriously reduce the product's survival rate, but will not kill or harm the surfactant.
Approximate cost to treat a cubic yard: $13, depending on the application technique used.
Manufacturer's comments: A free sample is available for bench testing. The product is used primarily for odor control. It can be used with other products.
Field users' contacts: Over 800 clients.
