SAN CLEMENTE, CA, Oct. 17, 2004 (PRWEB) -- Regenesis, a manufacturer of innovative environmental remediation products, announces the introduction of ORC AdvancedTM, which the company describes as state-of-the-art technology for stimulating aerobic bioremediation of contaminated groundwater.

As the name suggests, ORC Advanced is an improved version of Regenesis' Oxygen Release Compound or ORC®, which the company introduced in 1995 and which has been used to remove petroleum hydrocarbons (BTEX and MTBE) and other aerobically degradable contaminants at more than 10,000 sites worldwide.

ORC and ORC Advanced are designed specifically for in-situ treatment of petroleum-based hydrocarbon contamination or any aerobically degradable substance in the groundwater environment. Both products are supplied as nontoxic, environmentally benign powders that are mixed with water to form an injectable slurry, which is then pumped into the subsurface contamination zone with readily available direct-injection equipment. Contact with groundwater causes the material, over a period of months, to gradually release molecular oxygen, which is then used by naturally occurring microbial populations to flourish and rapidly degrade or break down the contaminants into harmless end-products. In most cases, site remediation with ORC or ORC Advanced is extremely cost-effective and simple, with minimal site disturbance, no above-ground piping or mechanical equipment to be installed and/or maintained, and no disposal of hazardous materials.

"ORC Advanced represents an important step forward because it offers maximal, sustained oxygen release for up to 12 months on a single injection," said Stephen S. Koenigsberg, Ph.D., Regenesis' Vice President for Research and Development. "Without an adequate, sustained oxygen supply, the microbial breakdown of contaminants will slow down sharply or stop altogether. ORC Advanced addresses this issue with greater oxygen content (17 percent by weight) and a patented Controlled Release Technology (CRT) that slows the rate of hydration and enables the continued free movement of the liberated oxygen into soil and groundwater."

Contaminants that can be treated effectively with ORC or ORC Advanced include gasoline and fuel additives (including BTEX and MTBE), diesel fuel, kerosene, jet fuel, gas condensates, fuel oils, lubricants, bunker oil, PAHs, vinyl chloride (VC), arsenic, certain pesticides/herbicides and certain industrial solvents (aldehydes, alcohols and ketones). Results from recent ORC Advanced projects will be presented and published at the Battelle-sponsored Eighth International Symposium on In Situ and On-Site Bioremediation in Baltimore, Maryland, June 6-5 2005.
