Pezzi' Road, Stockt+rin, CA <br /> Dear Mr. Altree: <br />�t <br /> This report describes the sampling of monitoring wells at the above referenced site <br /> for the first quarter, ending March, 1996. Wright Environmental Services, Inc. <br /> (Wright) was retained to coordinate sampling and chemical ianalysis of the site <br /> monitoring wells. Previous reports ar6, on file with the San Joaquin County Public <br /> Health Services- Environmental Health'Division (PHS-EHD) regarding the removal of <br /> impacted soil discovered during the remov2l of underground fuel storage tanks One <br /> groundwater monitoring well currently exists on-site. <br /> Field Sampling Procedures <br /> One monitoring well was sampled on March 27, 1996. 71�e sampler,proceeded to <br /> purge well volumes Ca cA164lati6h was `done for the well, follow grsounding <br /> measurements) of growl dVafer` ffom -the well using, a disposable bailer <br /> Measurements of conductivity; 1JH, 'and water temperature were obtaindd between <br /> each well volume, and not6d on •the attached biroundwater,Sampling Inf6rmation <br /> Sheets presented as Appendix A. Once the stabilization,of the readings were noted <br /> (aquifer water was assumed to be entering the"W;al% and the well was allowed to <br /> recharge to about 80% of the initial water 11vel, the sample was collected from the <br /> well. Purge water was stored on-site in barrels. A new disposable bailer was used to <br /> obtain each well groundwater sample which was placed in laboratory(prepared glass <br /> bottles leaving no headspace, and immediately=placed on ice for shipment`to Priority <br /> Environmental Laboratories Inc in Milpitas,l'California (a State Certified Te�.ssting <br /> Lab).
