from Upper Little Deadwood Gulch and from the Idaho Seep also suggest the water quality in <br /> Little Deadwood Gulch and the spring flow from a historical collapsed Idaho No. 1 adit are <br /> comparable. <br /> 9.0 CONCLUSIONS <br /> To refine presented conceptual models particularly in the vicinity of the Idaho No. 1 tunnel, a <br /> Little Deadwood Gulch water budgets is being developed to define lag time from runoff events <br /> to production from the Idaho seep. To accomplish this,periodic flow measurements and field <br /> water quality sampling will be obtained from contributing mine workings, when accessible, in <br /> order to collaborate the conceptual flow model. <br /> The surface and groundwater quality monitoring program will continue to analyze Idaho seep for <br /> common ions to determine if changes in water chemistry can be related to the changes to runoff <br /> water quality. In addition, water samples will be (as necessary) sampled from the May Day No 1 <br /> and 2 respectively when or if the adits discharge. In addition, if there is a May Day No. 1 seep, <br /> water quality samples will be periodically analyzed for common ions. The water quality data will <br /> be used to validate flow through the mine areas. <br /> The general lack of water production from the mine workings, the small recharge area of the <br /> units above the mine, and the on-site observations, suggest that there are no extensive saturated <br /> zones in the mine area. <br /> REFERENCES <br /> a.
