SOP <br />Revision 6 <br />1/8/1988 <br />Page 8 of 13 <br />2.2.3 Solid Samples <br />2.2.3.1 Soils <br />Sampling points are usually prescribed by site investigators. Samples <br />are to be taken by hand auger, trier, or directly by penetrating the sample <br />metal tube into the soil. Appropriate sampling containers must be used and <br />samples transported under refrigerated condition. <br />2.2.3.2 Waste <br />Liquid waste in drums shallow tanks and pits sampled with a Coliwasa <br />in order to obtain a representative sample safely. The sampler allows <br />sampling of immiscible layers in a represenative manner. Moist, sludgy <br />waste should be sampled with a trier. Dry granular waste can be taken with <br />a thief. <br />2.2.4 Air Samples <br />Air is sampled into an appropriate container at a constant rate during <br />selected time intervals by means of a diaphragm pump. The pumping rate <br />' used depends on the type of compounds, detection limits and sampling time. <br />3.0 Preservation and Storage <br />The Laboratory will comply with the recommended EPA Methods protocols <br />for sample preservation, storage, and holding times for various analytes. <br />container4.0 Sample Receipt <br />o Inspect shipping or outer container's overall condition.
