23 January 2015 <br /> AGE Project No . 06- 1457 <br /> Page 6 of 6 <br /> Remaining annular space above the bentonite seal will be filled to within one foot of the <br /> ground surface with a cement grout. The grout mixture will consist of Type 1/I1 portland <br /> neat cement and not more than 6 gallons of water per 94-pound sack of cement . Grout <br /> will be placed by pumping through tremie pipe . A flush mounted well cover will be <br /> installed at the surface and will be locked to prevent accidental filling . The SJCEHD will <br /> be notified for grout inspection at least 481hour for to conductinggrouting <br /> procedures . <br /> A cut view diagram of the proposed intermedia s is included as Figure 4 . <br /> 3 .4 . WELL DEVELOPMENT AND SURVEY <br /> Development will consist of a combination of bailing to remove the major portion of fine- <br /> grained sediment from inside the well , surging to flush out or draw in sediment from the <br /> filter pack, and additional bailing to finish the removal of sediment. Development <br /> activities will be continued until field parameter (pH , electrical conductivity, and <br /> temperature) readings have stabilized . Additionally , each well head elevation and GPS <br /> location coordinate will be surveyed by a licensed surveyor. <br /> 3 . 5 . GROUNDWATER SAMPLING PROCEDURES <br /> j <br /> Ground water sample collection will be performed in accordance with AGE ' s standard <br /> monitoring and sampling procedures , which have been included as Appendix B . <br /> 3 . 6 . EQUIPMENT DECONTAMINATION/WASTE MANAGEMENT � J <br /> All sampling tools used for sample collection , except for disposable bailers , will be <br /> thoroughly rinsed with clean water after being washed with a solution of Alconox. All <br /> down-hole drilling equipment will be pressure washed prior to starting each boring . <br /> Cuttings generated during drilling and rinseate generated during drilling and <br /> groundwater sampling activities will be containerized in properly labeled DOT-approved <br /> 55-gallon drums , and stored on-site in an area lacking public access . Disposal <br /> alternatives will be evaluated based on results of soil and water analysis . <br /> Advanced GeoEnvironmental Inc. <br />
