Water Quality Monitoring Report <br />Forward Landfill <br />During the 2016 monitoring year groundwater flow was generally directed to the north and <br />northeast. <br />Groundwater quality conditions beneath the Austin Unit during the 2016 monitoring year are <br />generally similar to those observed in the previous monitoring year. The following table <br />summarizes inorganic CL exceedances for DMP wells during the 2016 monitoring year. <br />AUSTIN UNIT CL EXCEEDANCES FOR 2016 MONITORING YEAR <br />WELL <br />CONSTITUENT <br />2016 MONITORING <br />PERIOD <br />AMW-6 <br />Bicarbonate, Calcium, Magnesium, <br />Nitrate, Potassium, Strontium, TDS <br />1Q16 <br />AMW-5R <br />Potassium <br />AMW-6 <br />Bicarbonate, Calcium, Magnesium, <br />Potassium, Sodium, Strontium, TDS <br />2Q16 <br />AMW-12 <br />Nitrate <br />AMW-6 <br />Bicarbonate, Calcium, Magnesium, <br />Potassium, Sodium, Strontium, TDS <br />3Q16 <br />AMW-6 <br />Bicarbonate <br />4Q16 <br />AMW-12 <br />Nitrate <br />As has been the case historically, several CL exceedances were noted for well AMW-6, during <br />the 2016 monitoring year. In addition, one or more VOCs were consistently detected at <br />quantifiable concentrations in well AMW-6. As discussed previously, well AMW-6 was <br />identified as a DMP well in the new WDR and Forward has requested that well AMW-6 be <br />reclassified as a CAP well. <br />In the CAP/EMP wells, 18 of 28 CAP/EMP wells reported one or more VOCs exceeding a PQL <br />during the 2016 monitoring year, with CAP well AMW-1 having the greatest number and <br />highest concentration of VOCs. An annual report discussing the CAP and EMP monitoring <br />results including a comprehensive discussion of corrective actions taken or planned was <br />prepared by Geo -Logic Associates (GLA, 2016) and is included in Appendix H. In response to <br />continued detection of VOCs in groundwater downgradient of the Austin Road Unit, the <br />RWQCB issued a CAO on December 8, 2008. Forward has installed 19 additional groundwater <br />monitoring wells downgradient of the Austin Unit as part of an on-going EMP investigation. <br />4.5.2 Surface Water <br />Site run-on and run-off control facilities are designed to effectively channel surface water to <br />lined holding and evaporation ponds on site. According to the Operations Manager, no surface <br />water was discharged from the facility during the 2016 monitoring year. With the exception of <br />the first quarter 2016, the surface water stations were reported dry.
