CAMBRIA <br /> discharges it directly into the sewer system GWE system analytical data and GWE system mass <br /> removal data are presented in Table 2 and Table 3, respectively MTBE concentrations and mass <br /> removal from well RW-1A 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 549 706 1,698,780 <br /> System <br /> Total (GWE) 946 1377 2,321,429 <br /> ANTICIPATED THIRD QUARTER 2003 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-1A 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 operation of the GWE system and continued monitoring and <br /> sampling of site monitoring wells to evaluate concentration trends at the site <br /> i <br /> 0783 2 <br />
