i 22 May 2013 AGE Project No . 11 - 1847 Page 3 of 6 format ( EDF) files of the laboratory analytical results will be submitted to the State of California GeoTracker database. 2 .4 . CONTINGENT MONITORING WELL INSTALLATION Once a target depth of 100 feet below surface grade (bsg ) has been achieved , one deep groundwater monitoring well may be installed at the boring location to further assess the vertical extent of the hydrocarbon plume . A determination will be made in the field based on soil samples and grab groundwater sample collected . The construction of the well will also be determined in the field at the direction of SJCEHD and based on field findings during the advancement of the deep boring . Procedures for the contingent well installation and completion are presented in Sections 3 .2 . and 3 . 3 . 2.4 . 1 . Well Development and Survey Following installation , the proposed well will be developed to maximize water flow and minimize the amount of fine-grained sediment drawn into the well during pumping or bailing . After development, elevation and location of all wells will be surveyed by a professional surveyor. Procedures for development and survey are presented in Section 3 .4. 2 .4 . 2 . Groundwater Sampling and Analysis Following installation , groundwater monitoring and sampling activities will be conducted for the proposed well on a quarterly basis for a minimum of one year (four sampling events). Monitoring activities will include recording depth to groundwater measurements and collection of groundwater samples for laboratory analysis by a CDPH-certified laboratory for contaminants listed in Section 2 . 3 . Groundwater sample collection protocols are described in Section 3 . 5. 2 . 5 , REPORT PREPARATION Upon completion of initial field work and receipt of final laboratory analysis, a report will be prepared presenting findings of the investigation . Additionally, following each quarterly monitoring event, a quarterly groundwater monitoring report will be prepared presenting Advanced GeoEnvironmental, Inc.
