I have the responsibility to decide <br /> which wells are used to make geologic interpretations, and why the data is questionable <br /> and therefore utilized. <br /> Attached is a site figure of the ground water data from fourth quarter 2008 utilizing two <br /> interpretations. <br /> The ground water flow is presented in blue, using the wells which have always had <br /> significant ground water for measurements (historical wells) . <br /> This data is collected from wells which have approximately 7-8 feet of ground water <br /> exposed to the screens. The alternate ground water flow direction utilizes a mixture of <br /> wells as presented in red; which include the shallow well screens (MW-5, MW-6, MW-7 and <br /> MW-8) which have only 2 .5 feet to <br /> 3 feet of ground water; and further do not screen exposed the dominant sand unit which is <br /> representative across the site. This well construction was at your office' s direction (no <br /> greater than 70 feet bsg) and these wells were dry in the third quarter of 2008; <br /> Additionally, these well fail to produce the minimum full purge volume during the <br /> monitoring procedures or drawdown during the monitoring procedures. Therefore, these well <br /> would marginally represent the upper ground water table. <br /> As depicted in the attached map the ground water flow directions are: west between wells <br /> MW-7 and MW-2; north between wells MW-3 and MW-8 or MW-5 and <br /> MW-2 AND north between wells MW-6 and MW-7; south between wells MW-7 and MW-6; and south <br /> to southeast between wells MW-2, MW-8 and MW-8; and the map depicts the ground water flow <br /> direction east from well MW-5 to MW-8. <br /> The denial of report based on your estimation is not appropriate, based on your statement. <br /> I feel you have wasted time by denying the report submission to geotracker over this <br /> element of the report. <br /> William Little <br /> California Professional Geologist #7473 <br /> wlittle@advgeoenv.com <br /> 1 (800) 511-9300 <br /> Advanced GeoEnvironmental Inc. <br /> 837 Shaw Road <br /> Stockton, Califorina, 95215 <br /> 1 (209) 467-1118 facsimile <br /> 1 <br />
