All hand -auger tools will be cleaned prior to <br />advancement at each boring location. Rinseate will be stored on-site pending disposal. <br />All soil borings will be permanently sealed to prevent vertical migration of potential <br />contaminants. Soil borings shall be abandoned by backfilling with a portland cement slurry <br />from the total depth to surface grade. <br />Should any additional sampling or other services beyond the scope presented herein, the <br />scope of work will need to be expanded with approval from the SJCEHD and Kaiser.
