NE - Not Established 11/06/15 Preliminary analysis: Exceedances are consistent with previously reported analytical data and thought to be primarily naturally occurring. 2 of 7 Ash Landfill Q88V5D Monitoring Well - Located north of Ash Landfill Pumping Station near gate in fence 2L Standard Field Data Field pH 6.5 to 8.5 7.0 Field Temperature (deg C)NE 18.7 Static Water Level (feet)NE 5.57 Field Specific Conductance (umhos/cm)NE 92.0 Turbidity (NTU)NE 149.5 Substance (Detect Exceedances) Iron 300 2750.0 All concentrations are in micrograms per liter (ug/L) unless otherwise noted. NE - Not Established 11/06/15 Preliminary analysis: Exceedance for Iron is consistent with previously reported analytical data and thought to be primarily naturally occurring 3 of 7 Ash Landfill Q88V6D Monitoring Well - Located beside Ash Landfill Pumping Station 2L Standard Field Data Field pH 6.5 to 8.5 6.0 Field Temperature (deg C)NE 19.2 Static Water Level (feet)NE 5.83 Field Specific Conductance (umhos/cm)NE 478 Turbidity (NTU)NE 5.25 Substance (Detect Exceedances) Manganese 50 229 All concentrations are in micrograms per liter (ug/L) unless otherwise noted. NE - Not Established 11/06/15 Preliminary analysis: Exceedance is consistent with previously reported analytical data and thought to be primarily naturally occurring. 4 of 7 Ash Landfill Q88V6D Monitoring Well - Located beside Ash Landfill Pumping Station 2L Standard Field Data Field pH 6.5 to 8.5 6.2 Field Temperature (deg C)NE 16.5 Static Water Level (feet)NE 61.51 Field Specific Conductance (umhos/cm)NE 135.0 Turbidity (NTU)NE 29.97 Substance (Detect Exceedances) Iron 300 612 All concentrations are in micrograms per liter (ug/L) unless otherwise noted. NE - Not Established 11/06/15 Preliminary analysis: Exceedance is consistent with previously reported analytical data and thought to be primarily naturally occurring. 5 of 7 Ash Landfill Q88V8D Monitoring Well - Located north of Ash Landfill Pumping Station 2L Standard Field Data Field pH 6.5 to 8.5 6.1 Field Temperature (deg C)NE 18.8 Static Water Level (feet)NE 7.81 Field Specific Conductance (umhos/cm)NE 165.0 Turbidity (NTU)NE 73.14 Substance (Detect Exceedances) Iron 300 667 All concentrations are in micrograms per liter (ug/L) unless otherwise noted. NE - Not Established 11/06/15 Preliminary analysis: Exceedance is consistent with previously reported analytical data and thought to be primarily naturally occurring. 6 of 7 Ash Landfill SSW1 Slurry Wall Pipe - Located in Ash Landfill Pumping Station Base Flow Wet Well 2L Standard Field Data Field pH 6.5 to 8.5 6.6 Field Temperature (deg C)NE 16.6 Static Water Level (feet)NE 599 Field Specific Conductance (umhos/cm)NE 599 Turbidity (NTU)NE 2.20 Substance (Detect Exceedances) Iron 300 2170 Manganese 50 648 All concentrations are in micrograms per liter (ug/L) unless otherwise noted. NA - Not Applicable NE - Not Established 11/05/15 Preliminary analysis: Exceedances are consistent with previously reported analytical data and thought to be primarily naturally occurring. 7 of 7 Ash Landfill UD1 Underdrain Pipe - Located in Ash Landfill Pumping Station Base Flow Wet Well 2L Standard Field Data Field pH 6.5 to 8.5 6.6 Field Temperature (deg C)NE 16.4 Static Water Level (feet)NE NA Field Specific Conductance (umhos/cm)NE 876 Turbidity (NTU)NE 1.45 Substance (Detect Exceedances) Arsenic 10 16.3 Iron 300 8660 Manganese 50 2110 Dissolved Solids, Total (mg/L)500 579 All concentrations are in micrograms per liter (ug/L) unless otherwise noted. NA - Not Applicable NE - Not Established 11/05/15 Preliminary analysis: Exceedances are consistent with previously reported analytical data. The iron and manganese exceedances are thought to be primarily naturally occurring. The arsenic, dissolved solids and sulfate exceedances are thought to be primarily from the Ash Landfill and Aerated Stabilization Basin.
