Biosolids facilities must meet or exceed federal, provincial, and local governmental law and adhere to strict odour standards set out by the City. Standards will be met using the best available odour management technologies and methods. They also contain small concentrations of other substances. When biosolids are applied to land, many of these substances break down or bond to the soil's surface. Strict guidelines ensure that biosolids slated for land application meet safety standards to protect soil, water and crops.
Municipal bylaws are also in place to monitor and control sewer discharges from local industry.
