SCREENING SOLID SAMPLES FOR VOLATILE ORG

2.1 A sample of soil or other solid material is carefully collected with minimal disturbance that could cause loss of volatile constituents. Sample collection may be accomplished using a modified plastic syringe or commercially-available coring devices intended for this purpose. 2.2 The sample plug is immediately extruded into a glass vial containing organic-free reagent water. The vial is immediately covered with aluminum foil and a modified septum cap. 2.3 The sealed vial containing the sample is hand-shaken for 10-15 seconds and the sample is visually examined to ensure that complete dispersion of the sample in the water has occurred.
