Treatment of Petroleum-Contaminated Soils
Product name: MZC
Product category: Enzyme supplement
Manufacturer information:
Brian Clark
Enzyme Technologies, Inc.
5228 NE. 158th Ave.
Portland, OR 97230
Phone: 503–254–4331 ext. 11
Fax: 503–245–1722
E-mail: brianc@enzymetech.com
Web site: http://www.enzymetech.com
Manufacturer's claims: Target-specific enzymes and biological enhancements increase degradations rates up to 90 percent. MZC is a unique product including a proven track record with repeatable, consistent results.
Site maintenance intensity: Typical monitoring period is 4 weeks. The period may be shorter or longer, depending on the conditions. Remote systems may operate for up to 2 months unattended.
Mobility: Products are typically supplied in 5-gallon pails. Very portable.
Cold climate applicability: Minimum recommended temperature is about 40 °F—not recommended for freezing conditions. In situ application may be conducted year round.
Approximate cost to treat a cubic yard: About $10 (product application only).
Manufacturer's comments: Many other types of bioremediation supplements are available.
Formal research: None available. Product reviews are covered in commercial and trade periodicals. See the manufacturer for a listing.

Product name: OCLANSORB
Product category: Absorbent
Manufacturer information:
Sanfransco, Inc.
P.O. Drawer A
601 South Meadow Lane
El Campo, TX 77437
Phone: 800-392-7736
Web site: http://www.oclansorb.com/
Manufacturer's claims: OCLANSORB internally encapsulates hydrocarbons on contact. OCLANSORB will absorb equal amounts of hydrocarbons by volume up to 12 times its weight. Meets leachate standards when used on some oils and pesticides and can be disposed in a landfill or by incineration in accordance with regulatory guidelines.
Site maintenance intensity: Not applicable.
Mobility: Available in a variety of forms.
Cold climate applicability: The more viscous the liquid, the slower the rate of absorption.
Approximate cost to treat a cubic yard: Not applicable.
Manufacturer's comments: Product handling accessories are available.
Product name: ORC (Oxygen Release Compound)
Product category: Oxygen supplement
Manufacturer information:
Regenesis
1011 Calle Sombra
San Clemente, CA 92672
Phone: 949–366–8000
Fax: 949–366–8090
E-mail: orc@regenesis.com
Web site: http://www.regenesis.com
Manufacturer's claims: ORC is a patented formulation of magnesium peroxide that slowly releases oxygen when hydrated. Very few similar products are available today. This product provides a stable time-released amount of available oxygen and increases "available oxygen" more per pound than any similar material.
Site maintenance intensity: No overhead or maintenance necessary beyond that required for the remediation technique.
Mobility: Packaged in 30-pound buckets.
Cold climate applicability: Effective in cold climates. Extremely cold sites should be field tested before full-scale implementation.
Approximate cost to treat a cubic yard: None given (highly variable, depending on contaminant type, concentration, and so forth).
Manufacturer's comments: Needs a minimum of 3-percent moisture content to activate. A Low pH or a high salinity accelerates the oxygen supplied by ORC.
Formal research: Odencrantz, J., Johnson, J., and Koenigsberg, S. 1996. Enhanced Intrinsic Bioremediation of Hydrocarbons Using an Oxygen Releasing Compound. Remediation. Fall. Vol. 6(4). New York, NY: John T. Wiley and Sons. p. 95–109.
Field users' contacts: Interested parties should contact Regenesis, which has closed more than 110 sites.

Product name: PDM-7
Product category: Microbial cultures
Manufacturer information:
Darryl Goodchild
Phase III, Inc.
916 East Baseline Rd., Suite 101
Mesa, AZ 85204-6603
Phone: 480–503–2847
Fax: 480–503–1077
E-mail: darryl@phaseiii.com
Web site: http://www.phaseiii.com
Manufacturer's claims: PDM-7 contains a blend of live, synergetic bacteria. These bacteria were specifically chosen for their ability to metabolize petroleum-based products, greases, fats, food particles, hair, cellulose, and detergents.
Site maintenance intensity: Depends on the remediation technique used.
Mobility: Comes in dry powder form that is safe to handle.
Cold climate applicability: Depends on the remediation technique used.
Approximate cost to treat a cubic yard: $13.35 per gallon.
Manufacturer's comments: PDM-7 HC is a strain of microbes specifically developed for the remediation of hydrocarbons.
Formal research: No formal citations were provided.
Field users' contacts: Phase III has a variety of case studies available on their Web site and in their product literature. No end-user contacts were provided.
