i <br /> 23 April 2001 <br /> AGE-NC Project No 97-0301 <br /> iPage 5 of 5 <br /> • Ground water monitoring concurrently with the California Tank-Line Inc site (3105 South <br /> El Dorado Street) The next quarterly ground water monitoring event is tentatively scheduled <br /> for 27 June 2001 <br /> • Continued utilization of wells MW-1 through MW-7 for characterization of ground water <br /> conditions at the site <br /> • Additional vertical ground water assessment is warranted near the former UST area and in <br /> t the area east of MW-7 AGE proposes to drill five cone penetrometer testing (CPT) soil <br /> borings to characterize the vertical extent of hydrocarbon-impacted ground water at the site <br /> • Based on the findings of the proposed CPT soil borings, AGE proposed installation of at <br /> ' least two deep-screened ground water monitoring wells, the screen intervals for the deep- <br /> screened monitoring wells will be placed to define and monitor the horizontal extent of the <br /> ' ground water plume in each informal hydrologic umt identified by the CPT investigation <br />! ' 6.0. LIMITATIONS <br /> Our professional services were performed using that degree of care and skill ordinarily exercised by <br /> environmental consultants practicing in this or similar localities The findings were based upon <br /> analytical results provided by an independent laboratory Evaluation of the hydrogeologic conditions <br /> at the site for the purpose of this investigation was made from review of previous consultants reports <br /> ' and a limited number of available data points(ground water samples)and subsurface conditions may <br /> vary away from these data points No other warranty, expressed or implied, is made as to the <br /> professional recommendations contained in this report <br /> 1 ! <br /> I <br /> ' Advanced GeoEnvironmental,Inc <br />
