GROUNDWATER SAMPLING PROCEDURES <br /> Pre-injection andpost-injection groundwater samples will be collected from wells MW-9 and VEW- <br /> 2 in accordance with AGE's standard operating procedures that are included in periodic ground <br /> water monitoring reports. The samples will be analyzed by a CDPH-certified laboratory for the <br /> chemicals listed in Section 2 . 1 . 3 . <br /> 3 . 3 . RegenOxTM INJECTION BORING ADVANCEMENT AND STRATEGY <br /> Prior to injection of the RegenOxTM slurry, depth to water will be measured with a Solinst water level <br /> meter from wells MW-9, VEW-2, MW- 13 , VEW- 1 (65) and EW- 1 for evidence of ground water <br /> mounding. Additionally, during injection, depth to water will be continuously measured in wells <br /> MW-9 and VEW-2 by suspending the Solinst water level meter sensor probe just above the measured <br /> water level and raising the meter as necessary. If excessive mounding is noted in well MW-9 or <br /> VEW-2, the injection rate will be reduced or the injection terminated. Depth to water measurements <br /> will be also collected from well MW-9, MW- 13 , VEW-2, VEW- 1 (65) and EW- 1 immediately <br /> following-the completion of the injections. — - <br /> Advanced GeoEnvironmenlal, Inc. <br />
