It will cover the period from June 2009 to January 2010 . <br /> This report will recommend making modifications to well EW-1 , which during DPE operations, <br /> contributes significant sediment to the system severely degrading performance. Well EW-1 was taken <br /> off-line on 09 February. The system now operates continuously without shutting down every other day <br /> or so. However, flip side is that EW- 1 and its surrounding area is highly impacted . <br /> As you are aware , we are using three wells (AWA , VW-1 and EW-1 ) that were not specifically designed <br /> for DPE . However, as of 19 January 2010 , the system had operated over 1 , 000 hours and a calculated <br /> mass of 0 .8 lbs of benzene and 11 lbs of TPH -g had been removed from the dissolved phase of the <br /> extraction and 35 lbs benzene and 942 lbs of TPH-g from the vapor phase. These numbers are <br /> preliminary and need to be PG-reviewed , but show the effectiveness of this remedy. <br /> Additionally, we will publish the semi-annual report next week, which covered the period from July to <br /> December with a sampling event of 12 October 2009 (preceded start-up). <br /> I will immediately draft the quarterly remediation report upon publication of the installation report. The <br /> quarterly remediation report will cover the period of February and March 2010 , and then every 3 <br /> months thereafter. We will stay caught up on reporting . <br /> Upon your review of the installation report, please evaluate our recommendation to modify EW- 1 as its <br /> importance to the remediation cannot be understated . Additionally, specifically designed DPE wells <br /> may need to be installed to address other areas of the impacted soil and ground water. <br /> Thank you , <br /> Art <br /> Arthur Deicke <br /> Advanced GeoEnvironmental, Inc. <br /> Stockton • Santa Rosa • Monterey • Brea • Spokane <br /> 1 -800-511-9300 <br /> adeickeC&ady,geoenv_.com_ <br /> www' udvgcoenv. com <br /> This email message is for the sole use of the intended recipient(s) and may contain confidential and privileged information. <br /> Any unauthorized review, use, disclosure or distribution of this enmail/fax in prohibited.
