Do we need to resubmit the report to <br /> Geotracker.since it has been.denied?. <br /> i <br /> I have attached two e-mails from the head chemist at McCampbell Analytical. One of the <br /> chromatograms is the TPHd analysis response from groundwater sample MW-1 collected. <br /> during the 4Q05 quarterly monitoring event. The other chromatogram shows the.TPHd <br /> standard overlying the MWA samples TPHd analysis.response. As you can see they are <br /> almost identical. You mentioned that you wanted to,see the method blank and all <br /> instrument blanks associated.with,this sample. I assume you would like to see the <br /> chromatographs for.these blanks, is.that correct? If so let me.know, I will work with the lab <br /> to get you the information you would like to see. In addition, if you would like,.I can.present <br /> this data in.a more formal letter if you would like,.please let me know. Thanks again for your <br /> cooperation <br /> Brandon S..Wilken, P.G. <br /> Cambria Environmental.Technology, Inc.. <br /> 510-420-3355 <br /> -----Original Message----- <br /> From: Vicki McCartney [EH] [mailto:vmccartney@sjcehd.com] <br /> Sent: Wednesday, February 08, 2006 2:45 PM <br /> To: Wilken, Brandon <br /> Subject: RE: Requested Jimco Truck Plaza Report <br /> Brandon,. <br /> I.reviewed the analytical data for samples collected by Accutite and find the <br /> narrative and data submitted in Tables 1 and 2 by Cambria to be correct. The split <br /> groundwater sample.results for MTBE have.a large discrepancy, but I will accept <br /> the results.submitted by.Accutite and will address this,in my next letter. <br /> I would like to see MWA's chromatogram and the chromatograms for the diesel.and <br /> motor oil standards run on the same instrument as the sample..Also,.I would like to <br /> see the method blank and all instrument blanks associated with this.sample. I will <br /> not comment about dropping motor oil analysis until.I have had time to.review the <br /> chromatograms. <br /> Thank you Brandon.. <br /> Vicki McCartney,Senior REHS <br /> San Joaquin County. <br /> Environmental Health Department <br /> 304 E.Weber Avenue <br /> i <br /> 2/13/2006 <br />
