' situations where recovery to 80%of static water level is estimated,or observed to exceed a <br /> f two hour duration,a sample will be collected when sufficient volume is available for a <br /> sample for each parameter. At no time will the well be purged dry so that the recharge rate <br /> causes the formation water to cascade into the well. <br /> In wells where fate-phase hydrocarbons are detected,the free-phase portion will be bailed <br /> E from the well and the volume removed recorded. A groundwater sample will be collected if <br /> bailipg reduces the amount of free-phase hydrocarbons to the point where they are not <br /> present in the well. Well sampling will be conducted using one of the aforementioned <br /> methods depending oB.the formation yield. However,if free-phase hydrocarbons pe=list <br /> 7 throughout bailing,theli a groundwater samples will not be collected. <br /> - Groundwater same'I-.containers are labeled with a unique sample number,location,product <br /> name and number, and date of collection. All samples are Iogged into achain-of-custody <br /> a form and placed in a chilled ice chest for shipment to a laboratory certified by the State of <br /> u California Department of Health Services. <br /> t <br /> i <br /> nl <br /> �M'H EXCELTECH,INC. <br /> Groundwater Sampling Protocol <br /> Latest Revision: March 28, 1990 <br /> f <br /> ME <br /> a, <br /> s t <br />
