Thanks_ <br /> Jim Barton <br /> James L.L. Barton, P.G. <br /> Engineering Geologist <br /> California Regional Water Quality Control Board Central Valley Region, 11020 Sun Center <br /> Drive, Suite 200, Rancho Cordova, CA 95670 office (916) <br /> 464-4615 <br /> fax (916) 464-4704 <br /> To comply with the Governor's order calling for furloughs, the Central Valley Regional <br /> Water Control Board Office and offices of the California Environmental Protection Agency <br /> are closed the second, third and fourth Friday of every month. I apologize for any <br /> inconvenience this may cause. <br /> >>> "Vicki McCartney [EH) " <vmccartney@sjcehd.com> 8/3/2010 4 :39 PM >>> <br /> Jim: <br /> After receiving your email that contained Leticia's responses by email dated June 23, <br /> 2010, to questions I had posed by email dated May 12, 2010, I sent a letter dated July 2, <br /> 2010, to the responsible party requesting the submittal of the GC/MS chromatograms for the <br /> TPH-d initial calibration curve, continuing calibration standards, method blanks, LCS/LCSD <br /> and MW/MSD that were associated with the three soil gas samples. A copy of the letter is <br /> appended for you and Leticia to review. <br /> In response to my request for this information, I received an email dated July 31, 2010, <br /> from William Little at Advanced GeoEnvironmental, Inc. (AGE) . Bill stated that <br /> "Additional chromatograms for TPH-d QA/QC for EPA method 8260 are not available, as the <br /> GC/MS method did not use a TPH-D standard for evaluation. A notation on the base of the <br /> analysis states TPH-d was performed by GC/MS analysis by TPH-d range compounds and the <br /> detection limit is 20, 000 micrograms per cubic meter. " <br /> I need to know how I should interpret the TPH-d results for the three soil gas samples <br /> (VP-1 through VP-3) since Cal Tech Environmental Laboratories reported TPH-d as non-detect <br /> at detection limit 20, 000 <br /> ug/m3 without running a curve, standard, blank, or QC/QC on the instrument. <br /> Jim, I would appreciate if you would have Leticia respond to my concerns about the TPH-d <br /> data. <br /> Vicki McCartney, Senior REHS <br /> San Joaquin County <br /> Environmental Health Department <br /> 600 East Main Street <br /> Stockton, California 95202 <br /> Phone: (209) 468-9852 <br /> Fax: (209) 468-3433 <br /> Email: vmccartney@sjcehd.com <br /> -----Original Message----- <br /> From: Vicki McCartney [EH] <br /> Sent: Thursday, June 24, 2010 10:07 AM <br /> To: 'Jim Barton' <br /> Subject: RE: Fwd: RE: Evaluation of Analytical Methods by theRegionalBoard'sChemist <br /> Good morning, Jim. <br /> 2 <br />
