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 SamDing <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 SamDing <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 1B. <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 /> DAForwardSAplan.doc <br /> Geologic Associates <br />
