Jeff Wong [EH] <br /> To: dsexton@advgeoenv.com <br /> Subject: RE: Steffano's I' <br /> Donna: <br /> I had spoken to Margaret, and- based on the influent and effluent results between November <br /> 2004 and February 2005, EHD agrees' with your proposal toltake the system off line. EHD <br /> also agrees with your recommendation to take samples one !Imonth later to check for rebound <br /> and effectiveness of the system. ,We can then discuss if '!GAC or catalytic oxydizer is the <br /> more cost-effective treatment alternative for the extracted contaminants. <br /> Jeffrey Wong, REHS <br /> SJEHD <br /> -----Original Message----- <br /> From: Donna Sexton [mailto:dsexton'@advgeoenv.com] <br /> Sent: Friday, March 25, 2005 10:03 AM <br /> To: Jeff Wong [EH] <br /> Subject: Steffano's <br /> Jeff, <br /> I am attaching the analytical from the monthly samples and start up. <br /> Initially we had 1, 500 ppb and in,'February we had 330 ppb that is a 78% <br /> decrease. The preliminary numbers ,for march are 700 ppb 1 should have the <br /> final analytical soon. Since it is a pilot test I would like to pulse for <br /> one month so that we gather data to see how effective that will be. Cost <br /> wise the electricity bill alone has jumped from 1, 500 to 2, 500 range to <br /> 3, 400 in the month of February. Looking- at the numbers, it makes sense. <br /> Digest the analytical and then we ;can talk. <br /> M <br /> I: Donna Sexton Advanced GeoEnvironmental, Inc.
