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 foil 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 rot a minimum <br /> of twenty minutes; allowing time for the air in the headspace and soil to equilibrate. <br /> An organic vapor analyzer(OVA)or photoionizadon 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 equilibrated,the probe of the organic vapor analyzer or photo ionization 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 it parts per million(ppm). <br /> The samples used for collecting organic vapor data are never submitted for analytical <br /> testing. <br /> i <br /> I° <br />
