As is recorded in Table 3, no floating product was detected in any <br /> of those wells except for Well MW-7, in which 0.14 ft. of floating product was measured. <br /> That thickness of LNAPL was an increase from the thickness of 0.02 ft, recorded on June <br /> 23, 2005. <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 October 21,2005. <br /> "I <br /> �.j <br /> F:- <br /> s-., <br /> <,17 <br /> i } <br /> i <br /> Sic <br /> i <br /> i <br />
