Groundwater Well Installation Standard Operating Procedure <br /> SWE-FSOP-601;Revision 1 Ahtna Southwest Environmental Operations <br /> drilling(whether through particular ground materials or to a particular depth) is difficult, and the integrity <br /> of the core sample is extremely important. <br /> Tremie. A tubular device or pipe used to place grout, bentonite, or filter pack in the annular space. <br /> Well Screen. A perforated, wire-wound, continuous wrap, or slotted casing segment used in a well to <br /> maximize the entry of water from the producing zone and to minimize the entrance of sand and fine <br /> particulates. <br /> 2.0 Relevant Documents <br /> This SOP focuses on the oversight and documentation of well installation activities and should be used in <br /> conjunction with state, county, and local well standards and other applicable SOPs, including the <br /> following: <br /> Standard Operating Procedures <br /> • SWE-FSOP-001 Field Documentation <br /> • SWE-FSOP-300 Series (various drilling methods) <br /> • SWE-FSOP-801 Equipment Decontamination <br /> • SWE-FSOP-802 Investigation Derived Waste Management <br /> Field Forms <br /> • SWE-FFRM-401, Well Construction <br /> • SWE-FFRM-004, Daily PFAS Sampling Checklist [PFAS Projects] <br /> 3.0 Equipment and Materials List <br /> The list below identifies equipment expected to be used by staff while supervising well-installation <br /> activities. <br /> • A bound, waterproof field logbook (FLB; e.g., Rite in the Rain"' or similar) with pre-numbered <br /> consecutive pages for field documentation <br /> [PFAS Project]: Field logbook made of standard/loose plain paper(non-weatherproof), held <br /> together by an aluminum or Masonite field clipboard. Alternatively, a spiral-bound <br /> notebook with non-weatherproof paper and/or cover can be used. <br /> • Waterproof, indelible pens/markers in black or blue ink <br /> [PFAS Project]: Use ball-point pens. Do not use markers, felt pens, or pens with water <br /> resistant ink. <br /> • Digital camera/video, cell phone, or other devices capable of digital imagery <br /> • Appropriate PPE <br /> The following materials are usually required for monitoring well installation. Review project-specific work <br /> plans for specific or unique materials or installation procedures. <br /> • Steel protective locking cover or flush-mount well box and locking cap <br /> Page 6 of 16 <br />
