A-3.7 Surface Soil/Sediment Sampling <br /> ~ Surface soil or sediment samples may be collected by driving samplers containing sample <br /> tubes, driving sample tubes, or collecting grab samples which are placed into laboratory <br /> prepared sample jars. An effort is made to pack the containers as full as possible to reduce <br /> air space. A fresh surface is exposed by scraping with a knife or shovel prior to sampling. <br /> Sampled material is described, and may be screened in the field. Collected soil/sediment <br /> samples are sealed, labelled and handled as previously described. <br />
