1.01 13 July 2012 AGE-NC Project No.96-0236 Page 5 of 13 • Total dissolved solids (TDS)ranged from 0.899 grams per liter(g/I; MW-2)to 1.505 g/I (MW-9). 4.1.2. Post-ISCO Injections Monitoring Event No. 1 On 25 April 2012, ISCO field parameters as described in section 3.3 were collected from wells MW-1A, MW-2, MW-4, DPE-1 and DPE-2 as part of post-ISCO injection ground water monitoring (Table 2); however, DO, ORP, salinity, and TDS were not measured in well MW-4 during this event. The following is a summary of the results: • Depth to ground water measurements ranged between 8.07 feet(DPE-1) btoc and 8.76 feet (MW-4) btoc; • pH ranged from 4.21 (DPE-1) to 6.54 (MW-2); • SC ranged from 1,258 pS/cm (MW-2) to 6,010 pS/cm (DPE-1); • Temperature ranged from 21.2 nC (MW-2) to 28.5 °C (DPE-2); • DO ranged from 0.82 mg/I (MW-2)to 13.85 mg/I (DPE-1)and from 9.4% to 168.9; • ORP ranged from -65.4 (MW-2) to 400.9 mV (DPE-1); • Salinity ranged from 0.64 (DPE-2) to 3.30 (DPE-1); and • TDS ranged from 0.845 g/I (DPE-2) to 3.960 g/I (DPE-1). 4.1.3. Post-ISCO Injections Monitoring Event No. 2 On 02 May 2012, ISCO field parameters as described in section 3.3 were collected from wells MW-1A, MW-2, MW-4, DPE-1 and DPE-2 as part of post-ISCO injection ground water monitoring (Table 2). The following is a summary of the results: • Depth to ground water measurements ranged between 8.20 feet(MW-1A)btoc and 8.85 feet (MW-4) btoc; • pH ranged from 2.56 (DPE-1) to 7.04 (MW-2); • SC ranged from 861 pS/cm (DPE-2) to 4,979 pS/cm (DPE-1); • Temperature ranged from 18.42 nC (MW-4) to 25.7 °C (DPE-2); • DO ranged from 1.15 mg/I (MW-4) to 32.40 mg/I (DPE-2) and from 12.4% to Advanced GeoEnvironmenlal,Inc.
