The initial <br /> task is to gain approval of this work plan by the SJCEHD and obtain well permits for additional <br /> subsurface investigation. The second work step is to install groundwater monitoring wells; <br /> of dissolved <br /> groundwater sampling of the new and existing monitoring wells will define the extent <br /> petroleum hydrocarbons.
