This <br /> update eliminated detail <br /> confusion and stylized the <br /> geology for more useful <br /> planning for targeting <br /> cleanup of sand-based <br /> contamination pathways. <br /> 5) Contamination smear <br /> zone tie with the <br /> underground lithology and <br /> groundwater fluctuations <br /> was re-assesed using a <br /> lithology tied to residual <br /> saturations tied to petroleum <br /> hydrocarbon type (gasoline, <br /> diesel, waste oil) on an <br /> incremental depth cross <br /> section in order to model <br /> approximately the primary <br /> product smear zone's lateral <br /> and vertical extent. The <br /> groundwater flow directions <br /> were superimposed to better <br /> assess the down gradient <br /> contamination migration <br /> flow direction. Refer to Fig <br /> 15 to Fig 25. <br /> 6) Thus the combined <br /> product plume Fig 26 was a <br /> composite of gasoline, diesel <br /> and waste oil product, <br /> submerged and unsubmerged <br /> was influenced by the site's <br /> NE groundwater flow <br /> direction, which had no well <br /> control to prove the lateral <br /> 11/10/2014 <br />
