As is recorded in Table 3, no floating product was detected in any <br /> of wells except for Well MW-7, in which 0.02 ft. of floating product was measured. <br /> ft <br /> That data is consistent with SJC's previously-stated as present the eSJoaquin <br /> Company Inc. 2006, 2004c, d, e) that the LNAPL that is p groundwater <br /> -' the area of the plume in the region of Monitoring Well MW-7 is not likely to be <br /> efficiently abated by simple periodic extraction from a 2-1n. diameter well. <br /> The small quantity of LNAPL present in Monitoring Well MW-7 was removed when that <br /> well was purged prior to recovery a groundwater sample on June 28, 2005. <br /> I <br /> i <br /> ,I -I <br /> f <br /> _i <br /> sic <br />
