regulations (i.e. Article 6 of 27 CCR). Drawing 13 of the )TD indicates the <br />locations of the perimeter gas monitoring probes -for the combined landfill <br />footprint. <br />2.2 GROUNDWATER <br />2.2.1 GROUNDWATER MONITORING WELLS <br />2.2.1.1 EXISTING GROUNDWATER MONITORING NETWORK <br />The groundwater monitoring network at the existing Forward and Austin Road <br />Landfills have been designed to provide early detection of a release from wastes to <br />groundwater. The monitoring systems currently installed weire;designed and <br />certified by a registered (geologist or civil) engineer. The boring logs were <br />prepared under the direction of a registered (geologist or civil) engineer and "have <br />been submitted to the RWQCB. <br />At the existing Forward Landfill, the groundwater monitoring" currently <br />includes 19 groundwater wells, with 10 of the monitoring wells positioned in well <br />MW pairs (e.g., MW -1 A, MW -1 B) to accommodate fluctuating groundwater elevations <br />in the area. The groundwater monitoring wells were typically constructed to <br />depths between 70 and 110 feet. Seven of the monitoring wells are included in <br />the post -closure monitoring,program that was implemented" following -c4osui�e of <br />WMU-A near the northeast corner of the facility. The remaining 12 wells are <br />included in the landfill's Detection Monitoring Program (Monitoring & Reporting <br />Program [M&RP] Order 97-141). The locations of the existing monitoring wells are <br />depicted on Figure 2. Table 3 lists the wells and identifies their current and <br />anticipated future uses. <br />The groundwater monitoring network at the existing Austin Road Landfill includes <br />13 groundwater monitoring wells that have been installed in accordance with the <br />facility's M&RP (Order 98-121) around the perimeter of the facility and within the <br />plume of impacted groundwater that extends north and northeast of the landfill. <br />The groundwater monitoring wells were typically constructed to depths between <br />80 and 100 feet. The locations of the existing monitoring wells are depicted on <br />Figure 2. Table 4 lists the wells and identifies their current and anticipated future <br />10 uses. <br />Forward Landfill PCPCMP 2-2 <br />L:\Allied\2000.193\Reports\FinaiPCPCMP:FL-sec2:8/22/01 BRYAN A.
