The samples were collected according to the Aegis SOP included in Attachment <br /> 1, and submitted under chain-of-custody to Resna Labs, a state-certified analytical <br /> laboratory. All samples were analyzed for concentrations of: <br /> • Total petroleum hydrocarbons (TPH), as gasoline, by GC-FID/EPA Methods <br /> 5030/8015. <br /> • Benzene, toluene, ethylbenzene, and total xylenes (BTEX) by GC-FID/EPA <br /> Methods 5030/602. <br /> Analytical results from May 1992 to date, are summarized in Table 2. Previous analytical <br /> results are included in Attachment 4. The laboratory report and chain-of-custody form are <br /> included as Attachment 2. TPH as gasoline and BTEX concentrations have remained <br /> below detection limits in all wells, which is consistent with the February 1993 event. <br /> Aegis recommends a copy of this quarterly monitoring report be forwarded to the <br /> following parties: <br /> Mr. Harlan Knoll <br /> San Joaquin County Local Health District <br /> Environmental Health Division <br /> Post Office Box 2009 <br /> Stockton, California 95201 <br /> Mr. Gordon Boggs <br /> Central Valley Regional Water Quality Control Board <br /> 3443 Routier Road, Suite A <br /> Sacramento, California 95827-3098 <br /> �4 <br /> 82-791C.RPT -2- <br />
