A preliminary study of inorganic contaminants and water quality in the Welland River watershed / K.R. Lum ... [et al.]. : En13-5/85-63E-PDF
"Surface water was sampled once from ten locations in the Welland River watershed and were analysed for dissolved Cu» Zn, Pb, Cd, Chloride, Nitrate. Fluoride, Sulphate andbacterial counts. The IJC Water Quality Objectives for the protection of aquatic life were exceeded at nine of the sites for zinc. The IJC objective for the protection of aquatic life was exceeded at three of the sites for Cu. The stations on the Old Welland Canal Spillway were found to be the most contaminated. Concentrations of the four metals were well within the maximum allowable concentrations for drinkinq water for all samples. Concentrations exceeding the maximum allowable drinking water guidelines for nitrate were measured at five stations. Effluents in the Spillway and those which have already received treatment show poor water quality on the basis of their fecal coliform populations. Total loadings of contaminants, in particular Zn and Cu, from the Welland Canal and the Spillway to Lake Ontario would be expected to be significant"--Abstract.
