Soil borings shall be abandoned by backfilling with cement grout from the <br />total depth to surface grade. Borings advanced below the groundwater table will be <br />abandoned with grout utilizing tremie procedures. The top three to six inches of the boring <br />abandonments will be completed flush to surface grade with concrete. The permitting <br />oversight (SJCEHD) will be notified for grout inspection at least 48 hours prior to <br />conducting grouting procedures. <br />EQUIPMENT DECONTAMINATION/WASTE MANAGEMENT <br />Prior to use, all sampling tools used for sample collection will be thoroughly rinsed with <br />clean water after being washed with a solution of Alconox. All probing rods will be cleaned <br />prior to advancement at each probe boring location. Any soil or water waste generated <br />during field activities will be containerized in properly labeled DOT-approved 55-gallon <br />drums, and stored on-site in an area lacking public access. Disposal alternatives will be <br />evaluated based on results of soil and water analysis. <br />REPORTING <br />The results of the site assessment will be submitted by a transmittal or letter report.
