Therefore, all recorded <br />monitoring events are considered Baseline. <br />Shallow monitoring wells SM-1 through SM-11 were constructed in 1985 in order to gather additional information <br />on alluvial/colluvial deposits within the permit boundary. They are depicted on Map 4-1. <br />Baseline Information Collection initiated on 8/2185 and not yet considered complete. <br />Point SM02 has not been influenced by mining. <br />Ground Water <br />Figure No. 19 <br />
