Zinc Zinc concentrations in the wetland acrotelm exhibit several anomalies, including high levels at background sites AAA-3 (1780 mg/kg) and A-3 (2092 mg/kg) and a low concentration at site C-1. The cause of these variations is not apparent but may be due in part to analytical interference. It is evident that zinc concentrations in the acrotelm are consistently elevated south of Montana Highway 200 from site

The cause of these variations is not apparent but may be due in part to analytical interference. It is evident that zinc concentrations in the acrotelm are consistently elevated south of Montana Highway 200 from sites to F-1 (Figure 8-6). Zinc concentrations in this area are generally an order of magnitude higher than most background levels. It is also evident that zinc concentrations are not very effectively reduced down-gradient from the Swamp Gulch discharge point. "ARBONATE MINE,.
