Third Floor <br /> Stockton, CA 95202 <br /> Subject: Sun West Liquors, 2449 W. Kettleman Lane, Lodi, CA LOP Site code: 503357 <br /> Global ID T0607700812 <br /> Dear Sir: <br /> Please find below a report on the groundwater sampling of monitoring wells for Sunwest Liquors. <br /> GROUNDWATER MONITORING REPORT FOR THE THIRD QUARTER <br /> 9/18/2001 <br /> SUN WEST LIQUORS <br /> History <br /> On 7/10/1998 Thorpe Oil ofLodi,California removed the three gasoline USTs from the Sun West property. <br /> Soil samples from underneath the USTs and the dispenser piping indicated that some leaks had occurred <br /> during the life ofthe gasoline sales operation.Foothill Engineering did a site investigation to determine the <br /> vertical and horizontal extent of the gasoline contamination on 8/13/1998 and 812111998. <br /> Geomatrix installed the monitoring well GMX-i at a location+/-25 feet south of the UST excavation and <br /> sampled first groundwater. That analysis is attached. Geomatrix also made three soil borings(GB#1,GB#2, <br /> and GB#3)with both soil samples and groundwater samples extracted(see attached map for location).All <br /> samples on GB41, GB#2, and GB#3 were non-detect for all compounds analyzed. <br /> The work plan of 5124/99 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. Soil <br /> samples were to be extracted at predetermined depths for laboratory analysis. A monitoring well to sample <br /> ground water was to be constructed in each of the soil borings. <br /> Groundwater sampling events have occurred on 7/12/99, 10/08/99, 2117/2000, 8/29/2000,10/29/2000, <br /> 12/22/2000,3/13/2001,6/26/2001,and this 9/18/2001 event.Laboratory data for all groundwater sampling <br /> analysis for each event is enclosed in a recap format. A copy of the complete Laboratory Certificate of _ <br /> Analysis is enclosed for only this sampling event. <br /> • <br /> 1 <br />
