r • preserved for analysis Depending upon field conditions, a water sample may be taken using a hydropunch or similar tool 5 If contamination continues below 80'bgs,the wells) will be completed with two (2) strings of blank& slotted 2" PVC One string will extend approximately 20 feet below the deeper water, or 80 feet bgs The other string will be placed across the first water, estimated to be at about 60 feet bgs PLATE IIIA is a schematic of one method of accomplishing that task However, the actual technique will depend upon conditions encountered during the work PLATE III is a schematic of a single zone completion 6 Drill solids will be placed on plastic and properly covered The soil will be sampled and analyzed as required for transport to an approved disposal facility 7 Depending upon the results of soil and water analyses, the soil borings will either be completed as monitoring wells as described above, or thoroughly grouted from total depth to the surface 8 If one or both soil borings are converted to monitoring wells, they will be developed and sampled within 36 to 48 hours after completion Water samples will be analyzed for BTEX, . TPHg, and TPHd using San Joaquin Co EHD approved tests and detection limits Depth to water in all wells will be determined during this work, and water samples will also be collected from MW-1 & MW-4 & analyzed for the same constituents as the new wells 9 If appropriate, the elevation and surface coordinates of each well will be determined by a licensed surveyor 10 All field operations will be supervised by a qualified geologist under the direction of a representative of the San Joaquin Co EHD Upon completion of the work, and receipt and analysis of the laboratory results, a report will be submitted to the San Joaquin County EHD for review and response W J titer&Associates D cem r 1, 1998 Re ed January 8, 1999 cc CVRWQCB - Mark List John Marci Gamson Law Corp 4
