Kettleman Lane, Lodi, CA LOP Site code: 5033571 <br /> Global ID T0607700875 <br /> Dear Sir: <br /> Please find below a report on the groundwater sampling event of May 31, 2005 for Sunwest Liquors. <br /> GROUNDWATER MONITORING REPORT FOR THE SECOND QUARTER <br /> i 2005 <br /> 05131.105 <br /> History <br /> On 7/10/1998 Thorpe Oil of Lodi, California removed the three gasoline USTs from the Sun West <br /> property. Soil samples from underneath the USTs and the dispenser piping indicated that some leaks had <br /> occurred during the life of the gasoline sales operation. Foothill Engineering did a site investigation to <br /> determine the vertical and horizontal extent of the gasoline contamination on 8/13/1998 and 812111998. <br /> Geomatrix installed the monitoring well GMX-1 at a location+1-25 feet south of the UST excavation and <br /> sampled first groundwater. Geomatrix also made three soil borings(GB#1,GB#2,and GB43)with both <br /> soil samples and groundwater samples extracted. All samples on GB#1, GB42, and GB#3 were non- <br /> detect for all compounds analyzed. <br /> The work plan of 5124199 called for the installation of three soil borings to be located on the Sun West <br /> Liquor property and the possible installation of a fourth soil boring on the south side of Kettleman Lane. <br /> Soil samples were to be extracted at predetermined depths for laboratory analysis. A monitoring well to <br /> - sample ground water was to be constructed in each of the soil borings.. <br /> Groundwater sampling quarterly events have occurred from 7112199 to 05131105. Laboratory data for all <br /> groundwater sampling analysis for each event is enclosed in a recap format(see attached recaps).A copy <br /> of the complete Laboratory Certificate of Analysis is enclosed for only this sampling event. <br /> On January 28, 2002, ACT Inc. performed a pump test on a 15" extraction well with a 6" PVC casing. <br /> The report for this pump test has been supplied as part of a Final Remedial Plan. <br /> 1 <br />
