control run-off, a perimeter ditch along the north, west and east ends of the unit directs all storm <br /> water run-off into a sedimentation basin on the east side of the site. The rest of the run-off from <br /> the unit gathers into a temporary sedimentation basin that is the excavation of a future module. <br /> There were no breeches to any of the run-on/run-off facilities during this monitoring period. They <br /> will continue to be monitored in the future. <br /> OTHER ANALYSIS <br /> ' Groundwater samples were collected from landfill supply well LW-1 and analyzed for all <br /> monitoring and field parameters. The well is not considered a point of compliance,which is stated <br /> ' in the WDRs. Results are included. <br /> COMPLIANCE RECORD <br /> ' The County submitted an Evaluation Monitoring Plan(EMP) to the Central Valley Regional <br /> Water Quality Control Board on October 21, 2002. The objective of Evaluation Monitoring was <br /> ' to delineate the suspected release affecting groundwater in the vicinity of MW-3. The results of <br /> evaluation monitoring were presented in the Engineering.Feasibility Report, submitted October 1, <br /> 2003, and is briefly summarized here. <br /> Groundwater samples from temporary borings TB-1 and TB-2 were found free of contaminants. <br /> A soil gas well, SG-1,was bored to sample soil gas above the water table near groundwater <br /> monitoring well MW-3. Four VOCs were detected. However, these compounds were not <br /> detected in the water samples taken at MW-3. Monitoring data from MW-3 continues to show no <br /> impact by VOCs at this time. These results lead to the conclusion that groundwater is not impacted <br /> by the presence of the Foothill Landfill at this time. <br /> Foothill Sanitary Landfill 8 Department of Public Works/Solid Waste <br /> 2ND Semester/Annual 2003 Groundwater Monitoring County of San Joaquin-Revised June 29,2004 <br />
