ORC Advanced® is designed specifically to provide enhanced, in situ aerobic bioremediation of petroleum hydrocarbons in groundwater. Upon contact with groundwater, the calcium oxy-hydroxide based product becomes hydrated providing a controlled-release of molecular oxygen (17% by weight) for a period up to 12 months from a single application. This dissolved oxygen is used by microorganisms to transform organic contaminants into carbon dioxide, water and microbial cell mass. ORC Advanced creates and maintains ideal conditions for aerobic biodegradation, resulting in enhanced attenuation rates up to 100 times faster than natural conditions. ORC Advanced provides remediation practitioners with a safe and highly effective means of treating petroleum contaminated sites.
Petroleum hydrocarbon contamination is often associated with retail petroleum service stations due to leaking underground storage tanks and pipework. As a result, ORC Advanced technology and applications have been tailored around the remediation needs of the retail petroleum industry and include: direct application into tank pit excavations, mixing with backfill, direct-push injection or application into injection wells (not monitoring wells). ORC Advanced is designed to work in conjunction with ISCO and physical abstraction methods to address residual dissolved phase contamination. the mixing and application of ORC Advanced is safe for both the remediation practitioner and the site user and will not have a detrimental effect on subsurface equipment or services, making it safe and easy to use on even live retail sites.
