The lab <br /> indicated that methods TO-3,TO-14,and TO-15 are specialized methods for ambient air testing that only a <br /> couple labs in the state do,and by method TO-3,benzene is reported,but the method is not appropriate for <br /> toluene,ethylbenzene,or xylenes. A second lab, Sierra Analytical,gave me a similar answer. Since EPA <br /> Methods 8015/8020 and 8260 are appropriate for soil vapor analysis and were the methods used,no changes <br /> need to be made to the analytical reports. <br /> David W.Herzog,R.G. <br /> Shaw Environmental,Inc. <br /> 1326 North Market Boulevard <br /> Sacramento,CA 95834 <br /> (916)565-4377(direct) <br /> (916)565-4356(fax) <br /> -----Original Message----- <br /> From:Vicki McCartney[ma_ilto:vmcea_rtrney cvsjcelid.com] <br /> Sent:Wednesday,February 12,2003 4:42 PM <br /> To: david.herzog@shawgip.com <br /> Subject: Air Sample Analyses <br /> David, <br /> Were you able to contact the laboratory and determine what air methods were used for analyzing air,samples <br /> collected at 3250 West Hammer Lane in Stockton,California in June 2002? The samples were analyzed for <br /> BTEX,gasoline,and fuel oxygenates. I would like to have the laboratory data sheets resubmitted with the <br /> correct methods indicated on the forms. <br /> 1 would appreciate a quick response to this e-mail. Thank you. <br /> Vicki McCartney <br /> 304 E.Weber Avenue <br /> Stockton,CA 95202-2708 <br /> Phone(209)468-3456 <br /> 2/14/2003 <br />
