Popis:	Higher land and energy costs have prompted interest in marshes for wastewater treatment. To date, four marsh treatment systems have been built in Ontario at Listowel, Cobalt, Bradford and Port Perry. Of these, the Cobalt marsh is unique in that it is situated in the area of a mine tailings basin. Because metals from mine tailings have been shown to reach the overlyinq waters, it was essential that the effect of leached metals on the micro-bial activities in the system be examined. Factors that were studied were chemical pollutant and pathogen removal, activities of sulfur and nitrogen bacteria, as well as inhibitory effects of toxic metals on the microbiota. Comparisons were made of data collected from the Cobalt and Listowel marshes. Although the metals present in the Cobalt area were shown to be potentially toxic to the marsh microflora, the concentrations of metals in the marsh were not hiqh enough to interfere with microbial activities.
