Table 3. Summary Statistics of Constituent Concentrations from Wells in Vicinity of Logan Wash Mine (Hester, 1983) and LW -001 Mine Water <br />Notes: <br />1 Values as reported by Hester (ca 1983), units assumed to be mg /L and metals are assumed to be dissolved concentrations; <br />(9 alluvial wells, 12 deep bedrock wells (200 to 1,400 ft. deep), 15 bedrock wells near retorts, and 2 springs). <br />2.
