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 8/8/86 and not yet considered complete. <br />Point SM11 has not been influenced by mining. <br />Figure Number 14 <br />
