ARCADIS SOP: Groundwater Sampling Using HydroPunchTM 2 <br /> Rev.#: 01 1 Rev Date: March 3,2009 <br /> I. Scope and Application <br /> This document describes procedures for collecting discrete-depth groundwater <br /> samples using the HydroPunchTM sampling device(QED Environmental Services, <br /> Inc.), or equivalent, during drilling in unconsolidated materials. HydroPunchTm can be <br /> used to collect a single sample from a selected depth, or multiple samples from a <br /> single borehole to produce a profile of groundwater quality data versus depth. The <br /> HydroPunchTM sampler is typically driven through open-ended drill casing or hollow- <br /> stem augers. <br /> HydroPunchTM consists of a drive point, a stainless steel screen section, a sample <br /> reservoir integral within the tool body, and assorted 0-rings and check valves to create <br /> watertight seals within the various components. Two models of HydroPunchTm have <br /> been developed, having slightly different designs and/or component parts as shown on <br /> the attached HydroPunchTM schematic drawings. All components are made of <br /> stainless steel, Teflon, or other relatively inert materials. The tool can be disassembled <br /> easily for cleaning between samples. <br /> Although this document refers to groundwater sample collection, HydroPunchTM is <br /> also capable of obtaining samples of light or dense non-aqueous phase liquid (LNAPL <br /> or DNAPL, respectively), if present at sufficient saturation and pressure head at the <br /> depth of the ampler during deployment. <br /> II. Personnel Qualifications <br /> ARCADIS personnel directing, supervising, or leading groundwater sample collection <br /> activities using HydroPunchTM should have a minimum of 2 years of previous <br /> groundwater sampling experience and current health and safety training including 40- <br /> hour HAZWOPER training, site supervisor training, site-specific training, first aid, and <br /> CPR, as needed. Field personnel will also be compliant with client-specific training <br /> requirements. In addition,ARCADIS field sampling personnel will be versed in the <br /> relevant SOPs and posses the required skills and experience necessary to <br /> successfully complete the desired field work. <br /> III. Equipment List <br /> The following materials are required for the collection of discrete-depth groundwater <br /> samples using HydroPunch TM. <br /> HydroPunchTM sampling device provided by drilling subcontractor <br /> 9%op-lihrary4eformatted sops 2008\hydrogeology sops\398782-groundwater sampling using hydropunch.doc <br />
