Show Table 7. Suggested ground- water- quality monitoring program for aquifer sites located in the vicinity of tar sands development. ( Adapted from State of Colorado, 1982, and Flug, 1985.) Parameters ammonia nitrate- nitrite phosphate arsenic cadmium iron manganese mercury selenium sulfate zinc Frequency Measure field water quality parameters ( water temperature, pH, and specific conductance) monthly. Record elevation of water level in the well at the time of sampling. Sample water for complete chemical analysis two times per year. Dissolved species preferred ( when applicable). Infrequent fraction analysis to determine carbon make- up. Following completion of the recommended lease stipulation analysis for the protection of water resources, similar monitoring requirements may be proposed as stipulations in oil and gas leases affecting the recreation area. IV. B. Research IV. B. 1. Floodplain identification and management. An inventory of flood hazard zones would be funded to cover all significant undeveloped public use points in the NRA. A flood frequency analysis would be required together with an analysis of regional gauging records to estimate magnitude. A more detailed level of investigation would follow, using field analysis of the flood history of specific drainages by examining remnant alluvial deposits. water temperature specific conductance PH total dissolved solids calcium sodium magnesium alkalinity chloride dissolved organic carbon J^ DOC) DOC analysis by fraction 71 |
