- Abstract
Agro-industrial wastewater and municipal sewage were used to restore Frank Lake, a 1246 ha northern prairie marsh in southern Alberta, Canada, to provide waterfowl habitat and improve water quality. Mean annual inflow wastewater nutrient concentrations were 17 mg L-1 NH3-N, 30 mg L-1 NO3-N and 11 mg L-1 SRP. Mean flows greater than 5000 m3 day-1 loaded the marsh with 23 000 kg of P annually. Summer NH3-N, NO3-N and total phosphorus (TP) surface water concentrations were decreased by 76, 87 and 64%, respectively, as waters flowed through the first basin of the marsh. Winter treatment was less successful, with surface water NH3-N, NO3-N and TP reductions of 46, –26 (export) and 26%, respectively. Short-circuiting of water flow through the marsh and cold seasonal conditions with ice cover caused spatial and temporal variation in marsh treatment. Continued high loadings to the marsh may lead to sediment saturation, eutrophication or phosphorus export from the marsh.
