However, it is clear that the efficiency of this wetland in the removal of manganese is at least an order of magnitude less than for iron. Aluminum The relationship between the Swamp Gulch discharge and elevated aluminum levels in the acrotelm are the least distinct of the metals evaluated, possibly due to ICP iron interference as suggested

Aluminum The relationship between the Swamp Gulch discharge and elevated aluminum levels in the acrotelm are the least distinct of the metals evaluated, possibly due to ICP iron interference as suggested by the low recoveries found in the NBS standards. Relative concentrations at several sites (BC-1, C-2, D-1, E-1, E-2 and F-1) are apparently two to three times higher than background levels at AAA-3, AA-2 and A-3 (Figure 8-3). However, the reported aluminum values at sites CD-I, CD-1-2, and , all close to the Swamp Gulch discharge point, were similar to CARBONATE MINE^ / MJJ 'I.
