• 09 May 2002 AGE-NC Project No 96-0232 Page 6 of 18 Utilizing a Blue-White Industries F-2000 flow meter, flow rates were measured and recorded on 03 January, 04 February and 27 March 2002 at 24 42 GPM, 24 14 GPM and 24 20 GPM, between 01 January and 31 March 2002, field observations of effluent-flow rates were generally recorded between 24 14 GPM and 24 58 GPM (Appendix B) 3 6 RECEIVING WATER MONITORING RESULTS In accordance with the requirements of RWQCB Monitoring and Reporting Program No 5-00-119, monthly ground water pump-and-treat receiving water(R-1 and R-2)monitoring was performed for total dissolved solids, flow rate, specific conductivity (EC), pH and turbidity on 03 January, 04 February and 27 March 2002, observations noted in a log book (Appendix B) Included floating or suspended matter,discoloration,bottom deposits,aquatic life,visible film-sheen-coatings,fungi and potential nuisance conditions Water monitoring could not be performed from R-1 during the above monthly monitoring events because there was no upstream water flow Because there was no upstream flow at R-1 and the upstream area was dry, the downstream flow rate at R-2 appeared to be equal to the ground water pump and treat effluent flow rate of approximately 24 5 GPM Observations logged in a notebook indicate that there was no floating or suspended matter, discoloration, bottom deposits or visible film-sheen-coatings, however there was a small amount of algae growth at the bottom of the ditch Visible aquatic life at R-2 included minnows, crayfish, snails, insects and frogs Potential nuisance conditions observed included trash in ditch (i e fast food containers, tire, paper and dry bush cuttings) Utilizing an ICM water analyzer and a YSI-50 dissolved oxygen meter in the field,dissolved oxygen was monitored at R-2 on the above monitoring events at concentrations of 4 50 mg/l, 5 3 8 mg/l and 5 24 mg/l, respectively, EC values on the same days were recorded at 1,030 µmhos/cm, 920 µmhos/cm and 711 µmhos/cm, respectively, pH values were recorded at 7 17, 7 12 and 7 59, respectively, temperatures were measured 19 0 °C, 20 3 °C and 21 7 °C Laboratory analysis of R-2 grab water samples collected during the above monthly monitoring events reported turbidity values at 9 3 nephelometric turbidity units (NTUs), 2 7 NTUs and 5 9 NTUs, laboratory analysis of R-2 reported TDS values of 630 mg/l, 630 mg/l and 760 mg/l, respectively Analytical results are summarized in Table 2, field measurements and laboratory reports are in Appendix B and Appendix D, respectively • Advanced CcoEnvironmental,Inc
