GROUNDWATER SAMPLING PROCEDURES <br /> ' Prior to water sampling, the depth to water was measured in the monitoring wells with a water <br /> level probe and recorded <br /> ' Groundwater in the monitoring wells was sampled according to the following methodology: <br /> ' 1 The wells were checked for the presence of floating product by partially <br /> submerging a clear teflon bailer past the air/water interface to collect any <br /> rpossible product for measurement <br /> ' 2. At least three well volumes were removed from each well or the wells were <br /> purged dry, and the water level was allowed to return to $0% of original water <br /> level. The pH, conductivity, and temperature of the purgewater were measured. <br /> ' These data were recorded on the purge and sample data sheets <br /> 3. Samples were collected using a new disposable bailer for each well <br /> 4 Samples for analysis were transferred from the bailer to appropriately prepared <br /> containers Care was taken when transferring the water from the bailer to the <br /> ' containers to avoid turbulence The containers were filled and the caps slipped <br /> onto the containers so that no air bubbles were trapped. Samples were then <br /> placed on ice and chilled to less than 4°C <br /> QRTERLYIAPPENDX <br />
