cement.. The mixed grout will be recirculated through the grout pump prior to <br /> placement. <br /> • Grout placement will be performed using a commercially available grout pump <br /> and a rigid,side discharge tremie pipe. <br /> Well protective casings will be installed around all monitoring-wells on the same day <br /> as the initial grout placement around the well. Any annulus forinedbetween the <br /> outside of the protective:casing and the borehole will be filled to-ground surface with <br /> cement. <br /> The construction of.each well will be depicted as built in a well construction diagram. <br /> The diagram will be attached to the boring log and will graphically denote: <br /> • Screen location,_length <br /> • Joint location <br /> • Granular filter.pack <br /> • Seal <br /> • Grout <br /> • Cave-in <br /> • Centralizers <br /> • Height of riser <br /> • Protective casing detail <br /> I <br /> Monitoring Well Installation and Completion <br /> • Assemble appropriate decontaminated lengths of pipe,screen,and end caplsump- <br /> Make sure these are clean and free of grease,soil,and residue. <br /> • Attach the end cap/sump to the bottom of the screened section. Lower the screen and <br /> each section of pipe into the borehole,one at a time,.screwing each section securely <br /> into the section below.it. No grease, lubricant,polytetrafluoroethleyene(PTFE)tape <br /> or glue,may be used in joining the pipe and screen sections. <br /> Page 7 of 9 <br /> I <br /> well—install—SOF MONITORING WELL INSTALLATION February 2005 <br /> _ I <br /> I <br /> I <br /> i <br />
