i <br /> GRO verses 8015B +!" Page Y of 2 <br /> Vicki McCartney [EH] <br /> From: James Liang Damesl@californialab.com] <br /> Sent: Friday, January 07, 2005 12:22 PM <br /> To: Vicki McCartney [EH] <br /> Subject: Re: GRO verses 8015B <br /> Hi Vicki, <br /> Thank you very much for your info. <br /> When we purchased the new LIMS, it had the Gas/BTEX LIMS template with the method name of 8015GRO. We <br /> did not change it even though we run the method as EPA 8015 Mod. The carbon range is C7 to C14 for <br /> gasoline. However, when a sample contains a lot of diesel, some compounds will fall into the range and be <br /> quantified as gas. When this happens, we will QC-flag it. <br /> You remind me this confusion. I changed the method name moment ago. In the future,.our method for <br /> Gas/BTEX will be 8015M/8021 B. <br /> James Liang <br /> -----Original Message- --- <br /> From: Vicki_McC.a.rt.n_.ey.._.[EH1 <br /> To:jamesl@califomialabc..om <br /> Sent: Thursday, January 06, 2005 11:46 AM <br /> Subject: GRO verses 80156 <br /> Greetings, James. <br /> It was so nice to talk to you today. I am glad I had the opportunity to hear that your family is doing well. <br /> As I mentioned on the telephone, I am now working for San Joaquin County in Stockton, California. I am a <br /> regulator or inspector(I've been called other things too)for the Underground Storage Tank.Local Oversight <br /> Program. I oversee the clean up of soil and groundwater after underground storage tanks and associated <br /> piping have leaked. <br /> There is some concern by staff members related to reporting gasoline as Gasoline Range Organics (GRO) as <br /> opposed to reporting total petroleum hydrocarbons as gasoline (TPH-gasoline) by EPA SW-846 Method <br /> 8015B. Does California Laboratory Services report GRO or does the laboratory report gasoline as TPH- <br /> gasoline? Is there a difference between these two reporting methods as to the carbon ranges involved? <br /> Thank you for taking time to respond to my inquires;James. <br /> Vicki McCartney,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 /> 1/7/2005 <br /> f <br />
