05 May 2017 <br />AGE Project No. 95-0184 <br />Page 4 of 4 <br />3.4. BORING ABANDONMENT <br />All soil borings will be permanently sealed to prevent vertical migration of potential <br />contaminants. Soil borings shall be abandoned by backfilling with cement grout from the <br />total depth to surface grade. The top three to six inches of the boring abandonments will <br />be completed flush to surface grade with native soils or concrete. The SJCEHD will be <br />notified for grout inspection at least five days prior to conducting grouting procedures.
