Elevated levels found in the zone roughly described by sites C-1, , D-3 and E-1 are an order of magnitude above background sites. The concentrations at sites E-2 and F-l are approaching background levels. Of particular interest are the high lead concentrations found in near surface materials at sites F-2 and F-3 (Figure 8-5).

. Hydrochemical, vegetational and microbiological effects of a natural and a constructed wetland on the control of acid mine drainage . Mine drainage; Acid mine drainage; Wetlands. hydraulic conductivity of the underlying catotelm and the limited mobility of lead. Elevated levels found in the zone roughly described by sites C-1, , D-3 and E-1 are an order of magnitude above background sites. The concentrations at sites E-2 and F-l are approaching background levels. Of particular interest are the high lead concentrations found in near surface materials at sites F-2 and F-3 (Figure 8-5). These are likely the result of mining activities on the upper Blackfoot River above this site. A literature review on the phytotoxicity of selected metals (EPA 1987a) suggests lead concentrations observed in the elevated zone would be phytotoxic to most crops and may inhibit maximum vegetation production in the wetland.
