22 June 2001 <br /> AGE-NC Project No 97-0333 <br /> Page 8of1.0 <br /> 3 5 REPORT PREPARATION <br /> Quarterly reports will be prepared presenting the findings from ground water interim pump and treat <br /> activities The quarterly reports will include a description of work performed and the results of the <br /> groundwater analysis Conclusions and recommendations will also be included in the reports, if <br /> applicable The report will be in a format acceptable to RWQCB guidelines, and will be reviewed <br /> and signed by a California Registered Geologist <br /> ' 4.0. FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of a California <br /> Registered Geologist Procedures for dedicated low-flow pump installation, dedicated pressure <br /> transducer installation and pump and treat procedures are described below t <br /> 41 GROUND WATER EXTRACTION <br /> i <br /> lie i <br /> A Grundfos Rediflow dawn-well pump, tyke �F`5, equipped wrt1i ErarikIin 112 hp, 230V, 3-wire <br /> nlotui5 6-111 be installed in I-W-1 One-inch diameter Schedule 80 PVC pipe will be installed from <br /> the submersible pump and discharged through the well-head sanitary sea], a safety chain w11I be <br /> installed at the sanitary seal to prevent dropping the purnp to the well bottom lo minimi/e sediment <br /> intake through the pump, the bottom of the purnpfmotor assembly will be suspended approximately <br /> ' one foot from the bottom of the well Electrical wiring w Il] be connected frorn the top of the pump <br /> through Class I electrical connectors/Junction boxes and electrical conduit to the pump electric <br /> controller Ground water will be continuously pumped from the bottom of the six-inch diameter <br /> extraction well EW-1 at a low-flow rate between five and seven GPM and routed through <br /> underground PVC piping to a 1,000-gallon holding tank, dedicated Solinst Level Logger pressure <br /> transducers will be deployed in selected on-site wells to measure difference in ground water levels <br /> before well pumping versus during i4ell pumping <br /> ' 42 WLLI AND PROCLSS PUMP CON FROLLERS <br /> Both the submersible Grundfos pump at L,W-i and the ground water pump-and-treat process pump <br /> ' will be controlled by PunlpTec controlleis, the ground mater extraction pump will Operate <br /> independently on a sepafate controller Primp controls .gill he supplied by ail amperage tiLnsmg/tlmc <br /> control s�N itch This switch �N 111 detect any decrease in amperage when water level dropq helo4� th,, <br /> ' inpellot rntakc from thl GrundfW, pump I ]te pump Whtcll will be outfitted with autorn ited <br /> i✓3cctTOIIIe '11Lit AGI antieipatcs total giOLInd �tatei <br /> tdiufucc((,ioFu�nunnunttl Inc <br />
