APPEND&B <br /> RELD PROCEDURES <br />' Cone Penetration Testing Direct-Push Procedure and Borings <br />' Soil samples were collected using direct push drilling equipment, using 13/4-inch diameter <br /> hollow-stem rods fitted with acetate liners for continuous soil core sample recovery when <br /> needed The borings were logged by a Shaw Environmental, Inc geologist using the <br /> Unified Soil Classification System Soil samples for logging were collected at depth intervals of <br /> 4 feet or less, by advancing the hollow-stem rods into undisturbed soil The sampler was driven <br />' using a pneumatic hammer or hydraulic pressure All soils generated during drilling operations <br /> were placed in a drum until appropriate disposal <br />' Soil samples for laboratory analysis were retained in acetate liners, capped with Teflon& sheets <br /> and plastic end caps, labeled, and placed in sealed plastic bags These samples were transported <br />' on ice to the laboratory accompanied by chain-of-custody documentation (Appendix C) <br /> Groundwater samples were collected using a push-type sampler and small disposable or <br /> decontaminated bailers The push-type sampler was advanced to the bottom of the desired <br /> sampling interval and then an outer sleeve was retracted to expose an inlet screen A <br /> small-diameter bailer was lowered through the hollow push rods and the body of the sampler to <br /> withdraw a groundwater sample The groundwater samples were decanted into <br /> US Environmental Protection Agency (EPA)-approved containers, which vary in size, <br /> composition, and preservative, depending on the analyses to be performed The bottles were <br /> filled completely to force out air and to aid in forming a positive meniscus Bottles were capped <br /> with convex Teflon septa to seal out air, and were inverted and tapped to verify that no air <br />' bubbles remain The samples were then labeled and placed in a cooler on ice for transport to the <br /> laboratory accompanied by the appropriate chain-of-custody documentation (Appendix Q <br />' All downhole equipment was cleaned before and after each boring upon completion of drilling <br /> and sampling activities All borings were back-filled with neat cement grout <br /> A\TeehPub1120221 Don RDdgersMpls\SIRlSpnng 2We 51R(August)doc �_� <br />
