Soil Sampling Using Direct Push SOP requiring this procedure and ensuring execution of this procedure in accordance with the identified requirements described in this procedure. 6.0 Equipment/Supplies: The following is the typical list of equipment required for completing this procedure: • Field Safety Equipment Bag • Traffic control devices, as defined in the Antea Group HSSE Practices - Site Control Policy • Field logbook and appropriate field form(s) • Field Boring Logs • Waterproof permanent pens and markers • Mobile phone—with a digital camera • Hand-held GPS with sub-meter accuracy • Spare locks - for buildings, compounds, and well covers (if appropriate) • Keys -to access existing on-site locks (if appropriate) • Decontamination supplies/equipment (if appropriate) Procedure-specific equipment/supplies include: • Tape measure (in 0.1-foot increments) • Utility knife • Duct tape • Paper towels • Sample jars with labels • Cooler with ice • Ziploc bags • Photoionization Detector (or other screening meter) • Table for examining drilled cores 7.0 Procedure: Direct push sampling involves advancing a sampling probe utilizing a drop hammer or by applying direct hydraulic pressure using a slide or percussion hammer. Samples may be collected continuously such as at one-, two-, or four-foot intervals or at specific depth intervals. Two-foot intervals sampling is most common. Typically, a qualified subcontractor is used by Antea Group to perform the actual probing operation. To collect samples using push methods: Direct push sampling shall be conducted in accordance with the following procedure: 1. Decontaminate the direct push sampler to be used for soil sampling in accordance with Equipment Decontamination SOP. 2. Soil sampling using a direct push sampler is performed in accordance with Direct Push Drilling SOP. 3. Once the sampler is removed from the hole,unscrew the cutting shoe and pull the liner out from the sample tube. 4. The exterior of the liner should be labeled with the top and bottom depth intervals using a permanent marker. If more than one rod/liner interval is being collected from the borehole, all liners should be arranged in the order collected with the top of each liner oriented in the same direction. The use of a core catcher can often be used to identify the Control#:AG-10040-00 Page 5 of 8 File name:Soil Sampling Using Direct Push SOP
