<br />GROUND WATER MONITORING <br />Sediments in the Fish Creek valley up and downstream of the tipple ar,e <br />' monitored. One well located approximately one half mile upstream of the <br />tipple and one well immediately downstream of the tipple are monitored. The <br />upstream well is 008-AU-3 and the downstream well is 008-AW-3. <br />1 <br />Water Levels <br />' A plot of the historic water levels in the upstream alluvial well is <br />' presented on Figure 3. The historic water levels for the downstream well is <br />presented on Figure 4. The water levels in the wells show the typical <br />seasonal pattern of relatively rapid increase and decline due to spring <br />' runoff. This pattern indicates that any contribution from bedrock discharge <br />to the alluvium is minimal compared to the recharge from spring runoff. Due <br />' to low runoff in 1987 the water levels to the alluvial wells were lower than <br />most previous years. <br />' Water Quality <br />' Water quality samples are collected regularly from wells 008-AU-3 and <br />008-AW-3. These data are summarized in Tables 4 to 7. The historic field <br />' conductivities for the two wells are plotted on Figure 5. Seasonal <br />variation is not readily apparent but there is some indication that the <br />' conductivity decreases due to the recharge of spring runoff. The <br />conductivity in well 008-AW-3 is significantly higher than in well <br />' 008-AU-3. This is because well 008-AW-3 is directly downgradient of <br />reclaimed spoils. This phenomenon has been observed in other parts of the <br />' hasin. The increase in conductivity in well 008-AU-3 in the 1987 water year <br />is probably due to the increase in the dissolved solids concentration of the <br />water in Fish Creek at both the up and downstream sites. No other <br />' significant changes in water quality were detected during the 1987 water <br />year. <br /> <br /> - Z - <br /> <br />
