® RUN-OFF/RUN-ON FACILITIES <br /> The Foothill Sanitary Landfill utilizes several methods to control run-on and run-off. The natural <br /> topography of the area controls any run-on into the site. Also, the working area is a significant <br /> distance from the property boundary, so run-on from surrounding properties is minimal. <br /> To control run-off, a perimeter ditch along the north,west and east ends of the unit directs all <br /> storm water run-off into a sedimentation basin on the east side of the site. The rest of the run-off <br /> from the unit gathers into a sedimentation basin at the south of the southeast corner of Module 1. <br /> There were no breeches to any of the run-on/run-off facilities during this monitoring period. <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, as stated in the <br /> WDRs. Results are included. <br /> LINER LIMITS STAKED <br /> Liner limits were staked at south edge of module 1 (Figure 6). The photograph shows edge of <br /> liner stake with camera pointing directly east. <br /> Foothill Sanitary Landfill 10 Department of Public Works/Solid Waste <br /> 1sr Semester 2005 Groundwater Monitoring County of San Joaquin-July 29,2005 <br />
