Page 2 of 2 <br /> 4) The Q1-2014 Report updated the Site's geology (Fig 2, Fig by relying primarily on the <br /> CPT data instead of the widely different manual geologic descriptions by others and by <br /> cross referencing the Site Geology with the Adjacent Site Cross sections. This update <br /> eliminated detail confusion and stylized the geology for more useful planning for targeting <br /> cleanup of sand-based contamination pathways. <br /> 5) Contamination smear zone tie with the underground lithology and groundwater <br /> fluctuations was re-assesed using a lithology tied to residual saturations tied to petroleum <br /> hydrocarbon type (gasoline, diesel, waste oil) on an incremental depth cross section in <br /> order to model approximately the primary product smear zone's lateral and vertical <br /> extent. The groundwater flow directions were superimposed to better assess the down <br /> gradient contamination migration flow direction. Refer to Fig 15 to Fig 25. <br /> 6) Thus the combined product plume Fig 26 was a composite of gasoline, diesel and waste <br /> oil product, submerged and unsubmerged was influenced by the site's NE groundwater flow <br /> direction, which had no well control to prove the lateral extent of the product, which is the <br /> significant control gap to complete the investigation and to move forward to cleanup. <br /> 7) The minimum of two proposed monitoring wells DW6 and DW7 were proposed for real <br /> time current migration of the product instead of relying on out dated historical data. <br /> Concurrence from EHD. <br /> 8)A proposed strategy to cleanup was presented in the 1 Q-2014 Report. Concurrence from <br /> the EHD. <br /> Other point sand details can be expounded upon in the meeting such that our colleagues <br /> concur, and meaningful progress can result to benefit Allen Genetti's long awaited case <br /> closure. <br /> Please confirm. <br /> Andy <br /> 9/8/2014 <br />
