| RMT has improved on an innovative biotechnology that degrades recalcitrant organics, such as heavy petroleum products, PAHs, some agricultural chemicals, and other organics. The technology is an aerobic degradation process using a commercially available mixture of enzymes. Although various enzymes may be effective, extensive testing was performed to confirm the efficacy of a product made by Enzyme Technologies, Inc.,of Portland, Oregon. The enzymes are packaged, preserved, delivered to a site, and mixed with contaminated soil. The process does not involve the use of live bacteria or genetically engineered materials are used. ETT was tested on 90-year old MGP-impacted soil. In only 11 days, benzo(a) authracene was degraded from 4,700 g/L to 560 g/L.  RMT has tested the efficacy of this technology on actual contaminated soil and has witnessed encouraging results. As with all remediation technologies, certain applications produce optimal success. When using an extracellular degradation process with mixed enzymes, the most cost-effective applications involve relatively straightforward, but carefully engineered, in situ soil treatment using mechanical aeration and moisture control. Consider this technology for near-surface soil contaminated with any of the following:
RMT can perform a treatability study to determine if contamination at a particular site is amenable to degradation by an enzyme mixture.
