0 Groundwater Sampling Collection and Preparation <br />• Each sample was collected in approved laboratory supplied sample containers filled <br />completely and immediately capped, labeled, and placed in a cooler with ice. Samples for <br />VOC analysis were filled by pouring the sample down the sides of the container to minimize <br />aeration and capped with no airspace. <br />• Where a bailer was used for sample collection, a bottom -emptying device was inserted into <br />the bailer, and the sample was transferred from the bailer to the container at a rate so as to <br />minimize aeration. <br />• Collected samples, accompanied by a trip blank, were placed immediately in an ice -filled <br />cooler for transport to the state -certified testing laboratory. Samples were kept chilled (at <br />about 4°C) until delivery. <br />• A completed Chain -of -Custody form, detailing the sample I.D., date and time collected, <br />analyses requested, and other project information, accompanied each sample to the <br />laboratory. The Chain -of -Custody forms were signed and dated by all personnel retaining <br />custody of the samples (Appendix Q. <br />Surface -Water Sampling <br />The sampling protocols listed below were generally followed during surface water sampling <br />operations. <br />• Surface -water sampling was performed by submerging laboratory -supplied sample <br />containers, or a decontaminated dipper, in a slow moving portion of the surface water <br />channel at the designated sampling station. <br />• Sample preservation and Chain -of -Custody procedures described above for groundwater <br />sampling were also adhered to for surface water sample collection. <br />Leachate Sampling <br />Leachate sampling is performed monthly at the Forward and Austin Units and was completed as <br />follows: <br />Monthly leachate samples are collected and analyzed in the field for pH and EC and recorded <br />on a Well Data Sheet. In addition to monthly monitoring, a leachate sample is collected <br />annually during the fourth quarter monitoring period and submitted to the laboratory and <br />analyzed for the parameters listed in Table 1 B. <br />Sample preservation, order of collection, and Chain -of -Custody procedures described above <br />for groundwater sampling were also adhered to for leachate sample collection. <br />3 <br />D:\ForwardSAplan_t06.doc <br />Geologic Associates <br />
