DETECTION MONITORING SYSTEM <br />The detection monitoring program is intended to determine if waste <br />constituents have migrated from the landfill and to comply with <br />applicable SWAT and Subchapter 15, Section 2556(a) requirements. As <br />discussed in Section III.A., the system of ground -water monitoring <br />wells has been designed to detect the presence of leachate in ground <br />water immediately outside the landfill area. <br />Corral Hollow Creek is located approximately 200 feet south of the <br />landfill. Surface water will be sampled from one hydraulically <br />upgradient and one downgradient location in Corral Hollow Creek at the <br />locations indicated on Figure 1. Corral Hollow Creek is an intermit- <br />tent stream; if Corral Hollow Creek is dry at the time of sampling, no <br />surface water will be sampled. It should be noted that tailings piles <br />are located immediately south of Corral Hollow Creek in the vicinity <br />of the landfill. The proposed downgradient sampling location may <br />reflect input from these tailings piles. <br />C. WATER -QUALITY MONITORING PROGRAM <br />The water -quality monitoring program includes appropriate sampling and <br />analytical procedures that accurately measure waste constituents and <br />water quality. Analysis of ground water upgradient and downgradient <br />of the disposal site and surface water upstream and downstream should <br />provide a reliable indication of the impact of the disposal site on <br />water quality. Ground -water samples from the monitoring wells and the <br />surface -water samples will be analyzed for the following parameters, <br />which include those set forth in the October 1986 amended SWAT guide- <br />lines: <br />12 <br />Emon Associates <br />
