Therefore, <br />monitoring events are considered Baseline. <br />Shallow monitoring wells SM -1 through SM -11 were constructed in 1985 in order to gather additional infort <br />on alluvial/colluvial deposits within the permit boundary. They are depicted on Map 4-1. <br />Baseline Information Collection initiated on 8/3/85 and not yet considered complete. <br />Point SM05 has not been influenced by mining. <br />Ground Water <br />
