1993 Annual Hydrologic Report <br />• Page 6 <br />this year and in the past. Diagrams G95-15 thru 18 are <br />graphical representations of water levels in these piezometers. <br />Data pages GD-1 thru 8 is the result of full suite water analysis <br />done on these sites during the year. Diagrams G93-19 thru 22 are <br />trilinear representations of these water analysis. This water is <br />hydrologically connected to the Colorado River and shows some <br />similarities. The variation between the water qualities and <br />types cannot be evaluated with the little information available. <br />Specifically, it would be impossible to assess the affect of the <br />mining operation on this site without first having information on <br />preexisting conditions. This water quality and type information <br />may be helpful in determining the need for continued monitoring <br />of this site as required by the latest permit renewal. <br />MINE WATER <br />The annual mine inflows study for this year was taken the end of <br />September and the first of October 1993 and again is being made a <br />part of this AHR. The results of the study are given on data <br />pages MA-1 thru 3 and MB-1. A summary of past conductivity and <br />• flows from the monitoring locations are given on Tables M93-1 <br />As usual there are many differences in the monitoring results at <br />the Roadside Mine. These differences are primarily the result of <br />changes in mining locations; differences in water routing, piping <br />and pumping patterns; and general difficulties involved with <br />monitoring underground. Locations 3 and 23 continued to be <br />affected by surface irrigation. Flow at location 17 was reduced <br />by changes in piping; more water was handled at location 3. <br />Locations 24 and 25 continued to be large contributors this year <br />and resulted in continued high flows at 5, 10 and 14 which are <br />locations along its flow path. A larger H-flume was used this <br />year to allow good flow measurements at 10 and 14. A dewatering <br />hole was drilled into the 8 West panel allowing resumption of <br />flow from location 6. This flow is allowed to drain into the 7 <br />West sump. Just prior to last year's study, a hole had been <br />drilled into 9 West panel releasing a pool of water which <br />resulted in a high flow for location 15. This year the flow at <br />this point is back to normal. Anew sump was activated in the <br />No.3 South Mains to supply water to the mining sections and to <br />provide water for dust control and firefighting. As a result of <br />this change, the use of the 7 West sump was discontinued and <br />diversion of water into the sump at location 18 was discontinued. <br />thru 5. Inflow monitoring locations are shown on the 1993 Mine <br />Inflows Map. During the year, full suite analysis was done on <br />samples collected at one location in the Roadside Mine and 3 <br />locations in the Cameo Mine. The result of these analysis are <br />given on data pages MA-4 & 5 and MB-2 thru 7. <br />
