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.
