Document Description
Under the oversight of the Regional Board, ConocoPhillips proposes to conduct a one-month feasibility test using C-Sparge to remediate the dissolved-phase petroleum hydrocarbon plume beneath the site. The C-Sparge technology combines low-flow [3 to 5 cubic feet per minute (cfm)] air sparging with ozonation to oxidize petroleum hydrocarbons into benign byproducts, carbon dioxide (CO2) and water (H2O). Ozone is generated onsite using a control panel with built-in compressor and ozone generator.
