s I <br /> rG. <br /> Pagel of 2 <br /> Vicki McCartney [EH] <br /> From: Vicki McCartney [EH] <br /> Sent: Wednesday, February 08, 2006 2:45 PM <br /> To: 'Wilken, Brandon' <br /> Subject: RE: Requested Jimco Truck Plaza Report <br /> Brandon, <br /> reviewed the analytical data for samples collected by Accutite and find the narrative and data submitted in <br /> Tables 1 and 2 by Cambria to be correct. The split groundwater sample results for MTBE have a large <br /> discrepancy, but I will accept the results submitted by Accutite and will address this in my next letter. <br /> I would like to see MW-1's chromatogram and the chromatograms for the diesel and motor oil standards run <br /> on the same instrument.as the sample. Also, I would like to see the method blank and all instrument <br /> blanks associated with.this sample. I will not comment about dropping motor oil analysis until I have had time to <br /> review the chromatograms. <br /> Thank you Brandon. <br /> Vicki McCartney,Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 304 E.Weber Avenue <br /> Stockton,CA'95202-2708. <br /> Phone: (209);468-3456. <br /> Fax: (209).468-3433 <br /> E-mail: vmccartney@sjcehd.com <br /> -----Original Message---- <br /> From: Wilken, Brandon [ma ilto:BWiIken @cambria-env com]. <br /> Sent:.Tuesday, February 07, 2006 2:27 PM. <br /> To: Vicki McCartney [EH] <br /> Cc: Scheele, Ron <br /> Subject: Requested Jimco Truck Plaza Report <br /> Hello Vicki, <br /> Attached is the report that you requested, which contains both tables and lab reports for both sets of data <br /> in question. I hope this answers all of your questions related to this data..If so, in your next letter., please <br /> include a paragraph mentioning that the data in the original report has been verified correct or something of <br /> that nature. <br /> In your letter responding to our Feasibility Test Report and Site Assessment Report, you mentioned that <br /> additional assessment is warranted. However, you did not request that we submit a workplan to complete <br /> vertical and lateral groundwater assessment at the site. In addition, you didn't mention anything about <br /> additional assessment near well MW-6.=We will need an additional letter requesting the.submittal of a <br /> workplan to complete delineation at the site. <br /> I spoke with the chemist at the McCampbell Analytical about TPHd and TPHmo being detected in-well MW- <br /> 1. The chemist said that TPHd is present in well MW-1 and the TPHmo that is reported is overlap from the <br /> diesel range hydrocarbons. Therefore, Cambria requests removing the TPHmo analysis from the <br /> monitoring and sampling plan at the site. I have requested well MW-1's chromatograph and the diesel and <br /> motor oil standard chromatographs from the lab to compare.I I will forward you this data once I receive it. <br /> Please give me a call with any questions or concerns. Thanks for your cooperation. <br /> 2/8/2006 <br />
