Qu'rterl'Report Third Quarter 2004 <br /> STRONG PROPERTY , <br /> 5157 WestBusiness Loop-205,Tr acy;.California + . <br /> 1.0. ..INTRODUCTION <br /> At the;request,of Messrs: Robert and,Mike:Strong, Advanced GeoEnvirorkmental' Inca(AGE),has f, <br /> prepared this quarterly report, for the property located at 5157 West Business Loop 205,'Tracy, <br /> California. The scope of work included theperformance of_-a uarterlY ground water monitoring ; <br /> event and preparation of this report. The site and the surrounding area are illustrated on Figure 1. <br /> Structures and monitoring well locations are illustrated on Figure 2.Quarterly monitoring data froiri' <br /> July' 1998 to the present is-summarized-in the tables:of this report.-Historical site investigation <br /> information'is'sulnmarized in'Appendix A. GeoTracker'confirmation pages of the submitted depth <br />'. 'to;Water and laboratory electronic deliverable format'(EDF'),files are included in:Appendix B., <br />' 2.0. 'PROCEDURES <br /> On 07.September 2004,,twelve monitoring wells (MW-1 through MW-12) and two domestic water <br /> wells (DWS•157.and-DW5055)were purged and sampled. All field work procedures and,reporiing <br /> requ, irements are in accordance with guidelines issued by the Central Valley Regional Waer Quality <br />� . Control Board(CVRWQCB)for subsurface.investigations of,uiiderground storage tank(UST)sites <br /> and guidelines'issued'by San Joaquin County Environmental Health Department(EHD)for.sampling <br /> of ground water monitoring wells. <br /> 2:1'. ; WELL MONITORING AND:PURGING <br /> On 07 September,'monitohng',wells MW 1.through MW-12 and domestic water wells DW5157 and' . <br /> DW5055 were purged and sampled A.Solinst.water level meter;was used to measure the depth.'to <br />' ground water to the nearest 0.01-foot in the,twelve monitoring wells relative to the tops of the=well . <br /> casings,. The ground water elevations,and.gradient were determined,from.these data'(Table.l); ' <br /> After recording water level measurements'new disposable"plastic bailers were,used to:purge each ; <br /> g . . <br /> inonitorin g well of standing water. 'Between #5.5 and` 8:25 ,gallons of water °(a minimum "of <br /> 3 easing-water'volumes per well)were removedfrom'eaeh well:Ground water temperature,pH and <br />' conductivity were measured at tegular intervals.during purging using an Oakton water analyzer.To ' <br /> r <br /> ..''Purge DW5157 and DW5055, a ho'se.bib was.opened. ori the wwater storage,tank.The pump was <br /> alloiwed to.cycle on and off for approximately:15 minutes:,Field sheets arid:data are included'in <br /> 1 Appendix C.'Purged'water was stored on'site.in-labeled, 55-gallon Department of Transportation <br /> (DOT)-approved`drums:, :. <br /> Advanced GeoEni ironmental,Inc. <br />
