Advanced Formula Oxygen Release Compound (ORC Advanced®) is a proprietary formulation of calcium oxy-hydroxide that produces a controlled release of oxygen for period of up to 12 months when hydrated.

To supply oxygen to accelerate the rate of naturally occurring aerobic contaminant biodegradation in groundwater and saturated soils.

ORC Advanced is typically applied using direct-injection techniques. This process requires ORC Advanced to be mixed with water to form an injectable slurry which is then pressure injected (using a pump) into the zone of contamination. Once in the aquifer, tiny ORC Advanced particles can sorb to and/or reside in the soil matrix and produce a controlled release of oxygen for periods of up to 1 year. ORC Advanced is also available in 2", 4" and 6" filter socks that can be emplaced in wells and removed when exhausted. Upon removal the spent socks can be replaced to restore the oxygen supply and maintain aerobic biodegradation as needed.
