ARCADIS SOP: Groundwater Sampling Using HydroPunchTM 5 Rev.#:011 Rev Date: March 3, 2009 • Retracting the sampler to ground surface—the drilling subcontractor will then open the sampler allowing collection of the groundwater sample[if using the HydroPunchTM I or else the HydroPunchTM II in groundwater mode(see Attachment A)] • Lowering a bailer or a peristaltic or inertia pump tube through the rods and body of the sampler, and retrieving the bailer or operating the pump to collect the groundwater sample[if using the HydroPunchTM II in hydrocarbon mode(see Attachment A)] 9. Perform field filtering of samples if required by the work plan, FSP and/or QAPP. 10. Obtain field water quality measurements if required by the work plan, FSP and/or QAPP. 11. Label the sample containers at the time of sampling with the following information. • Project name and number • Sample location • Sample number • Date and time of collection • Sampler initials • Analyses required 12. Preserve, store, handle, and ship samples to the analytical laboratory under chain of custody procedures as described in by the worts plan, FSP and/or QAPP. VII. Waste Management Investigation-derived waste will be managed as described in the Investigation-Derived Waste Handling and Storage SOP. VIII. Data Recording and Management Borehole identification, sample depth, sample date and time will be recorded in the field notebook, the boring log, and/or the personal digital assistant (PDA). The sample will also be identified on an appropriate chain of custody form, as appropriate for submittal to an analytical laboratory for analysis, if required. Consider digital photography to record unusual field conditions or to document compliance. gisop-libmryvelormatted sops 2008ftdrogeology sopsU98782-groundwater sampling using hydropunch.doc
