Description

In Alberta, it is common practice to apply sludge or biosolids to agricultural lands as a nutrient source; however, this must be done in accordance with standards and guidelines developed by the government. The issues and benefits associated with this type of application are extensive. Issues involve contamination of the receiving soils with metals, chemicals, drugs and pharmaceuticals, as well as changes to soil properties and chemistry, from repeated applications. The benefits of sewage sludge application are its nutrient value and its use as a soil amendment rather than burning or landfilling it. The Guidelines ate designed to maximize benefits and reduce potential hazards.

Description

The effluent of the Cold Lake/Grand Centre regional sewage lagoon appears to have a minor impact on the quality of the Beaver River. The concentrations of nutrient parameters increased slightly in the river downstream of the effluent discharge. Total phosphorus increased from 0.080 mg/L at Beaver crossing to 0.090 mg/L at the border and then steadily declined to 0.040 mg/L at Highway 26 in Saskatchewan. Dissolved phosphorus increased from 0.032 mg/L at Beaver Crossing to 0.051 mg/L at the border and then declined to 0.008 mg/L at Highway 26. Conductivity also increased downstream of the discharge, however, the low conductivity of the effluent itself did not suggest a cause and effect relationship. The numbers of total and fecal coliforms did not increase downstream of the effluent and did not appear to be influenced by the lagoon discharge. These small changes occurred under extremely low flow conditions in the Beaver River. During flows more typical of November, the available...
