Page 7 of 8 <br /> monitoring events. <br /> 4)The Q 1-2014 Report updated <br /> the Site's geology (Fig 2,Fig by <br /> relying primarily on the CPT data <br /> instead of the widely different <br /> manual geologic descriptions by <br /> others and by cross referencing the <br /> Site Geology with the Adjacent <br /> Site Cross sections. This update <br /> eliminated detail confusion and <br /> stylized the geology for more <br /> useful planning for targeting <br /> cleanup of sand-based <br /> contamination pathways. <br /> 5) Contamination smear zone tie <br /> with the underground lithology and <br /> groundwater fluctuations was re- <br /> assesed using a lithology tied to <br /> residual saturations tied to <br /> petroleum hydrocarbon type <br /> (gasoline, diesel, waste oil)on an <br /> incremental depth cross section in <br /> order to model approximately the <br /> primary product smear zone's <br /> lateral and vertical extent. The <br /> groundwater flow directions were <br /> superimposed to better assess the <br /> down gradient contamination <br /> migration flow direction. Refer to <br /> Fig 15 to Fig 25. <br /> 6)Thus the combined product <br /> plume Fig 26 was a composite of <br /> gasoline, diesel and waste oil <br /> product, submerged and <br /> unsubmerged was influenced by <br /> the site's NE groundwater flow <br /> direction, which had no well <br /> control to prove the lateral extent <br /> of the product, which is the <br /> significant control gap to complete <br /> the investigation and to move <br /> forward to cleanup. <br /> 7) The minimum of two proposed <br /> monitoring wells DW6 and DW7 <br /> were proposed for real time current <br /> migration of the product instead of <br /> relying on out dated historical data. <br /> 11/3/2014 <br />
