f <br /> A MEM <br /> S <br /> ADDENDUM <br /> SITE ASSESSMENT REPORT <br /> FORMER ISC WINERY SITE <br /> 1 WEST TURNER ROAD, LODI, CA <br /> INTRODUCTION <br /> On February 1 , 1990, the report "Site Assessment Report <br /> Update and Work Status, Former TSC Winery Site, 1 West <br /> Turner Rd. , Lodi , CA" was submitted to the Department of <br /> Health Services with an extra copy for the Regional Water <br /> Quality Control Board. Certain work was proposed in order to <br /> complete the assessment of possible aquifer infiltration and <br /> to establish if possible the piezometric surface of the <br /> groundwater. This addendum to that report should complete <br /> those tasks and finalize site assessment, but it is not <br /> intended to undertake remediation which is still under con- r <br /> sideration by Jim Thorpe oil, Inc. <br /> ACTIVITY <br /> There are three monitoring hells on site, which were used <br /> for both water sample testing and in establishing the piezo- <br /> metric surface in a previous report documented in the main <br /> body of the ISC Winery Report to which this is an addendum. <br /> These wells had all been sheared by earth moving equipment <br /> and new elevations run on the stubs. In order to protect the <br /> wells from vandals, the well tops had been cut off and <br /> lockable steel caps installed. Because accurate measurements <br /> of the well tops were not kept, re-surveying is again <br /> necessary. All measurements of water and bottom levels will <br /> be made from the top of casing (toc) . <br /> On March 22, 1990 an attempt was made to purge the three <br /> wells and to hail them clean (develop them by bailing) . <br /> Persons present were: Richard Thorpe, Jim Thorpe Oil, Inc. ; <br /> Dennis Allen and Bill Hunter, Consultants; Darlene Reuss and <br /> Greg Lyon, DHS; and Andy Bakinowski and Laura Valley, <br /> Groundwater Technology, Inc. , who supplied an electric water <br /> level detector and a 1" ID bailer. A water supply truck con- <br /> taining City of Lodi municipal water, connecting hoses and <br /> pvc pipe for purging the wells was also on site. Samples of <br /> the water in the truck were taken by Richard Thorpe in <br /> containers supplied by Canonie Labs. <br /> Well No, 1, the westerly well, was Entered first. Fill was <br /> found at about 36' toc. The wash pipe was placed in the well <br /> to the point of fill and water was introduced by gravity. <br /> Immediate returns of muddy water and silt were obtained. The <br /> well was washed for about 10 minutes with relatively_ c't_ean__-_ _-__-__--_____-______-___-___ <br /> --- ---- <br /> - - water-obtained at -the end.- Owing-to the water ruck set up, <br /> no estimate of water introduced into any of the wells was <br /> obtained. An attempt was made to bail this well, but owing <br />
