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-I 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). I have attached excel spreadsheets for wells MW-1, <br /> MW-2,MW-3, MW-4A, MW-4B 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 /> MW-1 : March 2004 <br /> MW-2: March 2007 <br /> MW-3: September 1999 <br /> MW-4A: July 2004 <br /> MW-413: October 2004 <br /> MW-5:No Detection <br /> MW-6: February 2006 <br /> 6/30/2014 <br />
