The objective of this report is to compile and synthesise existing information from government and industry sources on the nature of liquid effluents from municipalities and non-pulp mill industries in northern Alberta River basins. Information was obtained from 16 continuously discharging municipal sewage treatment plants, 77 periodically discharging sewage plants, and 62 licensed industrial discharges such as oil sands plants, coal mines, cement plants, and wood products operations. Information presented includes: description of wastewater treatment methods used; releases of treated sanitary wastewater; quantity and quantity of sewage treatment plant data; characteristics (chemical, nutrient, microbial, toxicological) of sanitary wastewater discharges; industrial effluent characteristics; and impacts on the aquatic environment. Gaps in the data are also identified
