09 October 2013 <br /> AGE- NC Project No, 11 -1847 <br /> Page 3 of 5 <br /> a report of findings and recommendations . <br /> 2 .3 . MONITORING WELL INSTALLATION , DEVELOPMENT, AND SURVEY <br /> All proposed soil boringswill be single-completed as shallow groundwater monitoring wells. <br /> The proposed monitoring wells will be screened at depths of approximately 25 feet to <br /> 45 feet bsg . Depth of the screened interval may vary or be reduced overall according to <br /> hydrogeologic conditions encountered while drilling . Following installation , each well will <br /> be developed to maximize water flow and minimize the amount of fine-grained sediment <br /> drawn into the well during pumping or bailing . The top of each newly installed well casing <br /> (well head ) will be surveyed to determine its elevation relative to North American Vertical <br /> Datum 88 . An as built diagram of the proposed construction of the proposed wells has <br /> been included as Figure 3 . <br /> 2 .4 , GROUNDWATER SAMPLING AND ANALYSIS <br /> Following the installation of the new monitoring wells, groundwater monitoring and <br /> sampling activities will be conducted on the wells on a quarterly basis fora minimum of one <br /> year (four sampling events) ; monitoring activities will include recording depth to <br /> groundwater measurements and collection of groundwater samples for laboratory analysis <br /> by a CDPH-certified laboratory for the analytes noted in Section 2 .2 . <br /> 2 . 5 . PREPARATION OF REPORT OF FINDINGS <br /> A report documenting the findings of the well installations, development and surveywill be <br /> prepared following performance of field work and receipt of all applicable data . Additionally, <br /> quarterly reports will be prepared following each groundwater monitoring event. Each <br /> report will include a description of work performed and the results of the groundwater <br /> sampling and analysis . Conclusions and recommendations will also be included , if <br /> applicable for each report. All reports will be in a format acceptable to the EHD and <br /> CVRWQCB , and will be reviewed and signed by a California Professional Geologist. <br /> 3.0 . FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of <br /> a California Professional Geologist. Procedures for the well installation , soil sample <br /> collection , well development and well sampling are described below. <br /> Advaneed Geo Cnvironmenlal, Inc. <br />
