Page 3 of 4 <br /> If the laboratory is using water-phase standards instead of gas-phase standards for the calibration curve, <br /> please confirm that the laboratory has analyzed a mid-level NIST gas-phase standard (vapor- <br /> phase validation check standard)that includes all of the target analytes and that the percent difference is <br /> twenty percent or less, especially for MTBE. The reporting limits should be less than or equal to the ESLs <br /> or CHHSLs for residential land use. <br /> I hope to issue the permit today for the three soil gas probes. <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: vmccartnevna sicehd.com <br /> From: Larry [mailto:larryw@amiadini.com] <br /> Sent: Friday, January 21, 20112:15 PM <br /> To: Vicki McCartney [EH] <br /> Cc: 'Dinesh Rao'; 'Yarone (Ron) Madnick' <br /> Suh ec+1 RF! \Mork Pian fnr cnfl roc CnPpr lnn <br /> Vicki, <br /> We would agree to add the following to the Description of the Work in the letter that was provided <br /> with the boring permit application: <br /> Duplicate Sampling <br /> The results of the field work utilizing a mobile laboratory will be independently confirmed through <br /> the collection of one duplicate soil gas sample in a 250 ml SummaTM canister. This duplicate <br /> sample will be analyzed using EPA Method 8260 in an off-site State-certified Environmental <br /> laboratory. The duplicate sample will be collected in an area where soil gas is suspected to be <br /> impacted with VOCs. <br /> We have added this statement to the permit letter, a copy of which is attached. <br /> We trust this will be acceptable. Please let us know should you require anything further. <br /> Sincerely, <br /> Larry Witwer <br /> Sr. Project Manager <br /> AMI ADINI &ASSOCIATES, INC. <br /> 4130 Cahuenga Blvd. Suite 113 <br /> Los Angeles, CA 91602 <br /> Tel# (818) 824-8102 <br /> Fax#(818)824-8112 <br /> e-mail: IarrVW amiadini com <br /> Web situ www.amiadini.com <br /> Larry Witwer <br /> 2/3/2011 <br />
