Therefore, all recorded monitoring events are considered Baseline. Shallow monitoring wells SM-1 through SM-11 were constructed in 1985 in order to gather additional information on alluviaUcolluvial deposits within the permit boundary. They are depicted on Map 4-1. Baseline Infonna[ion Collection initiated on 8/2/85 antl not yet wnsidered complete. Point SM02 has not been influenced by mining. Monitoring Point Table 12 (Revised 03/04)
