II <br /> APPENDIX D- GENERAL FIELD PROCED12ES <br /> I <br /> Soil samples were monitored for the potential presence of petroleum hydrocarbons visually and <br /> with a gas monitoring detector ([CGI]Gastech Model 400). Samples selected for combustible gas <br /> monitoring were placed in Zip-Lock or equivalent plastic bags. These samples were shaken to <br /> release any volatiles. A small hole was poked into the bag, and the sampling port of the Gastech <br /> introduced into the headspace above the soil sample for sampling and analysis. The reading in <br /> parts per million of hydrocarbon vapors was recorded on a field log. <br /> Soil samples were collected from the excavation equipment bucket at locations selected by the <br /> environmental consultant. Samples were collected by scooping soil into a new, laboratory <br /> supplied, wide-mouth, 8 ounces, glass jar into the r latively undisturbed soil extracted by the <br /> backhoe. The glass jars were sealed with teflon-coate lids. All soil samples were labeled as to <br /> sample collection location and depth and placed into ealable, plastic bags. <br /> The soil samples for laboratory analysis were placed in iced coolers for transport to the state- <br /> certified laboratory. Proper chain-of-custody protoc I will be followed always. <br />
