Therefore, all recorded <br />monitoring events are considen:d Baseline. <br />Shallow monitoring wells SM-1 through SM-11 were constructed in 1985 in order to gather additional information <br />on alluviaUcolluvia/deposits within the permit boundary. They are depicted on Map 4-1. <br />Baseline Information Collection initiated on 6/3/85 and not yet considered complete. <br />Point SM06 has not been in6uancetl by mining. <br />Ground Water <br />Figure No. 23 <br />
