The report summarizes existing water level <br /> and chemistry data. Very little-has changed since we issued the last quarterly monitoring report. <br /> Ground water still appears to be flowing west, and we still have 200 mg/f nitrate (NOO in the up- <br /> gradient well (MW-2). <br /> The Central Valley-Regional Water Quality Control Board (CV-RWQCB) has asked Unocal <br /> Corporation (Unocal) to install a shallow monitoring well on the west side of the Washington <br /> Street facility to determine if ground water with feed product concentrations is moving west from <br /> the site. Sierra-Pacific is waiting to receive written right-of-entry approvals from the Port of <br /> Stockton and Cargill, Inc. before proceeding with the installation. <br /> i <br /> Please call if you have questions or comments. <br /> Sincerely, <br /> SIE -PACIFIC GROUNDWATER CONSULTANTS, INC. <br /> I� <br /> JoMrEngineering <br /> en app, CEG-1133- <br /> Sen <br /> EG-1133- <br /> SeGeologist <br /> JSR:gn <br /> Enclosure - <br /> CC.
