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 In/ormation Collection initiated on 0/2/85 and not yet considered complete. <br />Point SM01 has not been influenced by mining. <br />Monitoring Point Table 11 <br />(Revised 03104) <br />
