Water Quality <br />Summaries of the water quality data for the eight Mine 1 ponds are presented <br />' on Tables 57 through 73 and on Figures 43, 43A and 48 through 51. The field <br />conductivity solids data shows some typical seasonal variation: the water <br />quality improves during spring runoff. Ponds A, B (Station 63), D, F, and H <br />(Station 57) appear to be impacted by spoil spring inflows. The discharge <br />rates from Ponds B and H are not significant during irrigation season and <br />therefore these ponds do not cause any significant impacts. The mean <br />irrigation season field conductivity for the ponds A, D and F are <br />approximately 2600, 2900 and 4000 umhos/cm respectively. These values are <br />similar to those measured in 1987. These values are also reflected in the <br />i conductivity level in Foidel Creek at station 8 which has a mean irrigation <br />season level of 2800 umhos/cm. Flowever the dissolved solids concentration <br />' of Trout Creek does not appear to be greatly effected by these Foidel Creek <br />levels due to the much higher flow of Trout Creek. For most of the ponds, <br />no sufficient increased levels in any parameters were observed in 1988. For <br />the ponds effected by spoil springs increased sulphates as well as dissolved <br />solids were observed. Also slightly increased sodium and SAR were observed. <br />Only accasional discharges during spring runoff were recorded from Mine No. <br />2 Ponds in 1988. Therefore no impacts to Fish Creek were observed. <br />Also of note, the water quality and flow rate of Station 87 and Spoil Spring <br />114 are almost equal. It appears that the high monitoring frequency of <br />Station 114 is redundant. - <br /> <br /> <br />1 <br /> <br /> <br />' - 11 - <br />
