This carefully designed process can help to cleanup sites and inhibit the flow <br /> of polluted groundwater by creating permeable oxygen barriers. <br /> A bioremediation system offers several advantages over other technologies. Other remediation methods may simply <br /> transfer the contaminants to another medium which requires removal, transportation, and possibly additional clean <br /> up. Bioremediation degrades contaminants on-site and has been shown to be more cost effective than other treatment <br /> technologies.The EPA actively promotes bioremediation as an ecologically sound, natural process. <br /> Oxygen is often the limiting factor in aerobic bioremediation. Moisture and nutrients (such as phosphorus and nitrogen) <br /> are generally present in sufficient quantities,however,oxygen is rapidly consumed by microbes which thrive in an oxygen rich <br /> environment.Without adequate oxygen, contaminant degradation will either cease or may proceed by highly inefficient <br /> anaerobic processes.Thus,additional oxygen is needed to stimulate further aerobic microbial growth and activity. <br /> ■ ■ Now <br /> Oxygen Release Compound (ORC®) and methods of its application are innovative technologies which enhance <br /> bioremediation. ORC is a patented formulation of a very fine, insoluble peroxygen that releases oxygen at a slow, <br /> controlled rate when hydrated. Its use has been demonstrated to increase the remediation of hydrocarbon <br /> contamination in soil and groundwater. <br /> FEATURES <br /> ■ Magnesium peroxide compound is activated by moisture <br /> ■ Patented technology controls and prolongs the release of oxygen <br /> ■ Moderate pH levels are maintained <br /> ■ Fine particle size has stable, long shelf life <br /> ■ No external coating of product is required to control rate of oxygen release <br /> ■ Generates higher dissolved oxygen levels than possible with air <br /> BENEFITS <br /> ■ Provides a passive, cost-effective, long-term oxygen source <br /> ■ Does not generate harmful residue;environmentally safe <br /> ■ Ideal for in-situ remediation where other methods are impractical <br /> ■ Will not disturb the flow pattern of the contaminated plume <br /> ■ Does not volatilize pollutants <br /> ■ Can be used as a redox control agent <br /> ©Pape <br />
