This report documents significant nutrient, organic and bacterial enrichment occurring in the Teeswater River. Field observations establish the presence of nuisance plant and algae growth through approximately a 2 km section of stream downstream from the Highway 4 bridge in the Village of Teeswater, Bruce County. Bacterial slime growth was observed fouling the cooling water and boiler blow-down discharge pipes from the Gay Lea Foods Cooperative Limited. These growths covered the entire stream bottom for approximately 500 m downstream from the Highway 4 bridge. Water sampling documented elevated nutrient, BOD5 and suspended solids levels being discharge from the Gay Lea Foods Cooperative Limited sewage treatment plant. Bacterial sampling defined significant bacterial loadings gaining access to the Teeswater River from the Gay Lea Foods Cooperative Limited discharges and the Teeswater storm sewer system. Biological data characterize an aquatic community typical of impaired water quality conditions. Water quality entering the village of Teeswater is impaired (nutrient enriched) from upstream land use practices. Additional water quality impairment occurs within the village of Teeswater and extends at least 2 km downstream. |
