'E <br /> ,6 <br /> situations where recoveryto 80% of l <br /> static water level is estimated, or observed to exceed a <br /> two hour duration, a sample will be collected when sufficienti`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. g <br /> In wells where free-phase hydrocarbons are detected, the free-phase portion will be bailed <br /> from the well and the volume removed recorded. A ground water p sample will be collected if <br /> bailing 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 on the formation yield. However, if free-phase hydrocarbons persist <br /> throughout bailing, then a groundwater samples will not be collected. <br /> Groundwater sample containers are labeled with a unique sal le�num <br /> cI p i� bet, location, product <br /> name and number, and date of collection. All samples are' logged into a chain-of-custody <br /> form and placed in a chilled ice chest for shipment to a laborator%, certified by the State of <br /> California Department of Health Services. <br /> { i <br /> Ep <br /> i <br /> a <br /> �i <br /> ik <br /> i <br /> it 1 <br /> 'k <br /> EXCELTECH, INC. <br /> Groundwater Sampling Protocol <br /> Latest Revision: March 28, 1990 <br />
