We are waiting for one set of <br /> groundwater samples that is being collected on March 28 to include in the 6-month pilot test report. If the <br /> pilot test concludes that ozone is working at the site, then the ozone system can be restart the week of <br /> April 25. Manganese was not detected in the baseline sampling and then was detected in the next five <br /> sampling events, but had a declining trend. <br /> For the SVE system, ConocoPhillips is requesting that the SVE system be shut down for 90 days, followed <br /> by rebound testing in May 2011 (specifics of the SVE rebound test will be outlined in the pilot test report <br /> being submitted 4-22-2011). <br /> Clinton Harms <br /> Senior Scientist <br /> Stantec <br /> 3017 Kilgore Road Suite 100 <br /> Rancho Cordova CA 95670 <br /> Ph: (916)861-0400 Ext. 228 <br /> Fx: (916)861-0430 <br /> Cell:(916)826-4186 <br /> stantec.com <br /> The content of this email is the confidential property of Stantec and should not be copied, modified, retransmitted,or <br /> used for any purpose except with Stantec's written authorization.

The EHD requests an update to the <br /> status of the ozone system and dates future milestones are anticipated. (i.e., return to <br /> online status, dates of additional sampling dates, and the date the report of the <br /> progess/findings of the 6-month injection period will be submitted to Geotracker (still <br /> early mid April?). <br /> Has magnanese been detected since the original sample date? <br /> do you still desire to d/c the SVE system? was the SVE system pulsed? or just the 03? <br /> let me know what's going on please. <br /> Mike Infurna. <br /> 3/14/2011 <br />
