Let me know if you need a <br /> stand-alone document. <br /> I have attached a table that summarizes groundwater concentrations last encountered from the Sierra <br /> Lumber Case I. As the table indicates, there were eight groundwater monitoring wells (MW-1 through <br /> MW-8) installed at the site. Wells MW-1,MW-3, MW-4A, MW-413, MW-5, MW-6, MW-7 &MW-8 <br /> all declined to non-detect levels. Well MW-2 was the only well with remaining impact in the well at the <br /> time of the last monitoring event(February 2006). 1 have attached excel spreadsheets for wells MW-1, <br /> MW-2, MW-3, MW-4A, MW-413 and MW-6 that project the TPH-g concentration linear trendline to <br /> time of water quality objectives (i.e. non detect). Also,wells MW-5, MW-7 & MW-8 did not encounter <br /> any TPH-g impact in groundwater and therefore I did not attach any graphs. <br /> Time to reach water quality objectives: <br /> 9/8/2014 <br />
