1.6 UTILITIES CLEARANCE <br />Prior to drilling, Underground Service Alert (USA) will be notified. Drilling <br />locations near overhead power lines will be checked for drill rig clearances <br />before drilling. Well locations will be adjusted as needed. <br />The wells will be drilled and developed by Gregg Drilling, a licensed C-57 <br />contractor. A sonic drill rig is anticipated to be used to drill the wells. If the <br />drilling becomes difficult, then a different type of drill rig will be used. <br />SWD's consulting geologist will observe the drilling and compile a hand written <br />drilling log. The log would be provided to EHD on-site upon request. Drilling <br />spoils will be stockpiled near the boring and dispersed near the vicinity of the <br />borings after well installation. <br />2.1 UNCOMPLETED BORINGS <br />If a boring is not drilled to depth by the end of a working day, the drilling area will <br />be cordoned with safety cones and the boring will be covered so that nothing <br />would fall inside. <br />If the initial boring does not encounter groundwater or it is difficult to drill, then the <br />boring will be abandoned as determined in the field by SWD. A new boring will <br />be drilled. Abandoned boring(s) will be grouted with neat cement. <br />It is anticipated that the groundwater well will be constructed immediately after <br />drilling. Well construction will be according to the well detail (Figure 2) and to the <br />technical specifications (Appendix A). SWD's consulting Engineer or Geologist <br />will log the well installation and provide final well logs. <br />3.1 EHD INSPECTIONS <br />Well installations will be in the presence of EHD inspector. SWD's will <br />notify EHD Unit 6 inspector(s) at least five (5) working days in advance <br />about the project schedule and the date and time for the first inspection. <br />Work Plan- FH -Groundwater Monitoring Well Installation San Joaquin County <br />8/14/2018 Department Of Public Works <br />2 Solid Waste Division <br />
