SPRING MONITORING <br />Natural Springs <br />One natural spring located in the vicinity of underground mining activities is monitored, <br />station 20-14 (6862014). The spring issues from the Twentymile Sandstone. The Spring <br />20-14 flow is historically very small (Figure 33) and there was no flow in 1992. A <br />sample and flow measurement was collected in the spring of 1993. The conductivity has <br />increased with decreasing flow rate (Figure 40) in the past. The conductivity levels are <br />within the levels normally recorded in the Twentymile Sandstone. The associated water <br />quality data for the spring is presented in Table 48. <br />Spoil Springs <br />One spoil spring system is monitored. It discharges from bond released spoils into Pond <br />E at the Tipple. The spring system consists of three small seeps (303-1, 303-2 and 303- <br />3) which coalesce at monitoring point FCT-87-1. Most of the samples collected have <br />been from 303-1, due to lack of flow from 303-2 and 303-3. The water data for the <br />springs is presented on Tables 49 to 51. Due to the small quantity of discharge (peak of <br />approximately 0.1 cfs), there is no detected impact on the water quality in Fish Creek. <br />~• <br />C~ -10- 6/10!94 1:23 pm <br />
