Low recharge wells will be purged dry and not resampled <br /> until either 80 percent of the original volume has recovered or on the following day, whichever is <br /> sooner. <br /> Condition No. 3 <br /> All samples will be collected with disposable PVC bailers since the groundwater levels are <br /> relatively shallow and the purging volumes are anticipated9f o be small. The bailers will have <br /> small-diameter tubes attachable at their base and ca lel of flow control. Volatile organic <br /> compound (VOC) samples (i.e., trihalomethanes an clf is e' by-products) will be collected <br /> first by slowly filling the vials (e.g., at a rate talo approximafy 40 seconds or more to fill a <br /> 40-milliliter vial).
