This study evaluated the occurrence of pathogens such as bacteria and human enteric viruses in bedrock aquifers across the country and explored the transport mechanisms that might have led to their presence. The results from this research are relevant for homeowners, public health authorities and provincial regulators.
This comprehensive report is a synthesis of both a literature review and the results of a stakeholder survey. The review is an analysis of the available academic, technical, trade, and ‘grey’ literature on nutrient removal and recovery and will help characterize drivers of the wastewater treatment industry such as policies, climate, and existing infrastructure. The [...]
This 2013-2015 project drew on the best available information to evaluate and interpret current knowledge, practice and regulatory frameworks, and identified feasible options for removal, recovery and reuse of nitrogen and phosphorus from wastewater treatment systems in Canada.
Land application is one of the most common end destinations for biosolids, and the only one that allows for the beneficial reuse of its nutrients. Although current regulations and agricultural management practices are generally considered to be protective of human and environmental health, the detection of an increasing number of ESOCs in biosolids and the [...]
Canadian Water Network's Canadian Municipal Water Consortium (CMWC) takes a deeper look into national priorities in the 2015 Canadian Municipal Water Priorities Report. Last year's inaugural Canadian Municipal Water Priorities report set the stage for the initiatives of the CMWC. The CMWC's Leadership Group (CLG) identified four priority areas within the themes of integrated risk [...]
Raw domestic wastewater or sewage contains a mix of various chemicals from products that are part of our everyday life, such as pharmaceuticals, personal care products, low sugar foods, domestic products, illicit drugs and natural hormones. Scientific studies have proven that these chemicals are not efficiently removed by conventional technologies in wastewater treatment plants, but [...]
This nation-wide project expands our knowledge on the removal of Emerging Contaminants in common Canadian wastewater treatment processes over a range of climatic and seasonal conditions. A significant contribution of this work is the concurrent analysis of a suite of aquatic toxicological endpoints, ranging from gene expression to whole organism responses.
The Canadian Council of Ministers of the Environment (CCME) in its development of the “Canada-wide Strategy for the Management of Municipal Wastewater Effluent” identified the need for coordinated scientific research as one of four components of the Strategy.
In response to developing the Canada-wide Strategy for the Management of Municipal Wastewater Effluent and the Canada-wide Approach for the Management of Wastewater Biosolids, both the Municipal Wastewater Effluent Coordinating Committee (MWWE CC) and the Biosolids Task Group (BTG) of the Canadian Council of Ministers of the Environment (CCME) identified a need for better national [...]
This report documents the evolution to date of the “National Research Agenda for Municipal Wastewater and Biosolids (the Agenda)”, which was developed jointly by the Canadian Water Network (CWN), Environment Canada, and the Canadian Water and Wastewater Association in 2012. The desired outcome of the Agenda was to: generate and prioritize, through research and consultation, [...]
