' SPOIL SPRING MONITORING <br />' A monitoring program was initiated in 1986 and will be conducted annually until <br />such time as the monitoring requirement 1s eliminated. As per the approved plan <br />' the annual mine wide survey will be conducted during May and springs will be <br />measured for flow and field parameters. If a spring is discharging 35 gallons <br />' per minute or greater then it will be monitored throughout the remainder of the <br />year in accordance with the monitoring plan. <br />' Flows ` <br />' The field data for the Spring 1986 spoil spring monitoring program is presented <br />on Table 28. The total flow from all four springs was only-0.040 cfs. <br />1 - <br />Water Quality <br />' The summary of the Spring 1986 spoil spring field data is presented on Table <br />28. The summary of the complete water quality data for the spoil springs is <br />presented on Table 29. The data indicates that the springs have a relatively <br />' low flow weighted mean dissolved solids of 810 mg/L. Due to the relatively low <br />dissolved solids concentration and very low flow rate the spoil springs are not <br />significant to the hydrologic regime. The spoil springs do not show increased <br />levels of trace metals or nutrients. <br />1 <br />1 <br /> <br /> <br /> <br />1 <br /> <br />-7- <br />
