"Water was sampled once in January, 1984, from ten sites in the Welland-St. Catharines area and were analyzed for chloride, nitrate, fluoride, sulphate, bacterial counts and dissolved copper, zinc, lead and cadmium. Comparison with the IJC water quality objectives for the protection of aquatic life shows that zinc concentrations were higher than the objective in nine sample and in the case of copper three water samples had concentrations above the objective."--Abstract. gccst Pollutants gccst Water quality Lum, K.
