'.; 09 May 2003 AGE-NC Project No 96-0232 ' Page 5of16 ' Utilizing an ICM water analyzer in the field, EC values were monitored on 27 January,24 February and 25 March 2003 at concentrations between 745 µmhos/cm and 790 µmhos/cm,pH values were monitored at between 7 13 and 7 34, and temperature values were recorded at between 18 7 °C and ' 219 °C, respectively Field monitoring results are summarized in Table 2 Utilizing a Blue-White Industries F-2000 flow meter, flow rates were measured and recorded on ' 27 January,24 February and 25 March 2003 at between 24 13 GPM and 24 80 GPM(Appendix A) ' 2 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-I and R-2)momtonng was performed for total dissolved solids, flow rate, specific conductivity(EC), pH and turbidity Observations noted in a log book (Appendix A) 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 27 January, 24 February or the 10 25 March 2003 monthly monitoring events because there was no upstream water flow Because there was no upstream flow at R-1, the downstream flow rate at R-2 appeared to be equal to the ground water pump and treat effluent flow rate of approximately 24 to 25 GPM Observations logged in a notebook during the 27 January, 24 February and 25 March 2003 I monitoring events indicate that there was no floating or suspended matter, discoloration, bottom deposits or visible film-sheen-coatings at R-2, however there was a small amount of algae growth at the bottom of the ditch Visible aquatic life at R-2 included minnows, insects and frogs Potential nuisance conditions observed at R-2 included trash in ditch(i a fast food containers,paper and dry bush cuttings), no potential nuisance conditions were observed at R-1 Utilizing an ICM water analyzer and a YSI-50 dissolved oxygen meter in the field,dissolved oxygen was monitored at R-2 during the 27 January,24 February and 25 March 2003 momtoring events at concentrations between 4 96 mg/1 and 5 40 mg/l,EC values were recorded on the same days between 732µmhos/cm and 788µmhos/cm,pH values were recorded at between 7 27 and 7 40,temperatures were measured at between 19 0 °C and 212 °C Laboratory analysis of R-2 grab water samples collected during the above monthly monitoring events reported turbidity values at concentrations between 0 1 and 3 2 nephelometric turbidity units (NTUs), a TDS value of 531 mg/1 was reported on 25 March 2003 Analytical results are summarized in Table 2, field measurements and laboratory reports are in Appendix C 1 Advanced GeoEnvironmental,Inc I
