DON RODGERS and JUI US MCKELVEY <br /> 515 W. Charter Way, Stockton, California <br /> Page 3 of 3 <br /> The air sparge test had not been approved by this agency for implementation as <br /> proposed. SJC/EHD recommends that the test be redesigned to demonstrate actual <br /> capture of sparged hydrocarbons, and be conducted again. Radius of influence, <br /> especially in mixed lithology, may be more appropriately determined from changes in <br /> dissolved oxygen concentrations, pressure, or depth to water measurements taken from <br /> the observation wells. <br /> If you have any questions or comments please call Lori Duncan at (209) 468-0337, or <br /> Nuel Henderson at (209)468-3436. <br /> Donna Heran, REHS, Director / <br /> Environmental Health Department X <br /> Z/ <br /> Lori Duncan, Senior REHS Nuel C.
