The jars are filled to <br /> approximately one half full. The soil samples are broken up to provided sufficient surface <br /> area to allow for volatilization. Aluminum fol! is placed over the mouth of the jar, The jar <br /> mouth is then capped with the lid. <br /> The jars are then placed out of direct sunlight and allowed to sit undisturbed for a minimum <br /> of twenty rrtinutes; allowing time for the air in the headspace and soil to equilibrate. <br /> M An organic vapor analyzer(OVA)or photoiouization detector(PID) is to be calibrated and <br /> the batteries checked prior to each use. After the headspace within the sample jar and soil <br /> vapor has equiUbrated, the probe of the organic vapor analyzer or photoionization detector <br /> ' should be inserted into the jar,puncturing the aluminum foil. The presence of any organic <br /> vapor detected should be measured and recorded in parts per million (ppm), <br /> i <br /> The samples used for collecting organic vapor data are never submitted for analytical <br /> testing. <br /> ^Fi <br /> q(W <br /> i t <br /> ' l <br /> 3 <br /> i <br /> t <br /> 3 <br /> 7 <br /> i <br />
