Surface Water Quality Monitoring Sites and Objectives
Schedule E of the Master Agreement on Apportionment contains PPWB water quality objectives for 12 interprovincial river reaches. Environment and Climate Change Canada monitors water quality at these 12 sites for the PPWB. The complete list of water quality objectives for the 12 sites is available here and is also available below for each river.
Total Ammonia Nitrogen (mg/L) **
The toxicity of ammonia relates primarily to the un-ionized form (NH3). The concentration of un-ionized ammonia present in water increases with pH and temperature. The values below represent total ammonia-nitrogen concentrations (at various temperatures and pH levels) above which accompanying NH3 concentrations may be harmful to aquatic life.
Total Ammonia (NH3 + NH4+)
(maximum levels expressed as N at various pH/temperature conditions)
