CAnABRIA <br /> • <br /> removal from well RW-IA are depicted in Figure 3 Volume and mass removal data for vacuum <br /> truck operations and the permanent GWE system are summarized in the table below <br /> Mass TPHg Mass MTBE Volume <br /> Removed(pounds) Removed(pounds) Groundwater <br /> Removed (gallons) <br /> Vacuum Truck 397 671 622,649 <br /> Operations <br /> Permanent GWE 354 508 794,831 <br /> System <br /> Total (GWE) 751 1179 1,417,480 <br /> ANTICIPATED FOURTH QUARTER 2002 ACTIVITIES <br /> Blaine will gauge and sample the site wells according to the established sampling schedule and <br /> tabulate the data Cambria will prepare a groundwater monitoring report <br /> • CONCLUSIONS AND RECOMMENDATIONS <br /> The petroleum hydrocarbon and MTBE concentrations in groundwater samples collected from <br /> the shallow wells this quarter are within the historical norm for this site Wells MW-5, MW-8 <br /> and RW-lA continue to contain the highest levels of hydrocarbons and MTBE Analytical data <br /> from offsite wells suggests the hydrocarbons and MTBE detected in onsite wells are remaining <br /> onsite <br /> Cambria recommends continued monitoring and sampling of site monitoring wells to evaluate <br /> concentration trends now that a groundwater extraction system is in operation, full time, at the <br /> site <br /> • <br /> 0783 2 <br />
