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 /> possible 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 80% of original water <br /> level The pH, conductivity, and temperature of the purgewater were <br /> measured These data were recorded on the purge and sample data sheets. <br /> i3 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 /> QRTERMAPPENDX <br />
