The aim of this project was to evaluate human health risk management strategies for disinfection byproducts (DBPs); and to assess the environmental implications of the operational stage through life cycle assessment of public swimming pools. The UBC Aquatic Centre was investigated as a case study and proof of concept. This project was funded by an NSERC Collaborative Research and Development (CRD) Grant with industry partners: AME Consulting Group, DB Perks and Associates Ltd., Acton Ostry Architects Inc., MJMA, Healthy Buildings IEQ, and Waterplay. This research was a collaborative effort between the Life Cycle Management Laboratory, UBC Athletics and Recreation (Vancouver), and Université Laval with chemical analysis provided by UBC, Laval and Université Montréal. Two sampling campaigns were conducted. Statistical analysis of the sampling results are presented in a paper under review for Science of the Total Environment. Modelling of the human health risk and lifecycle assessment will be presented in two additional papers. The results will help swimming pool operators in decision making for operational management to reduce DBPs and associated health risk.

Res’Eau-WaterNET is dedicated to maximizing benefits to small and rural communities by becoming the nation’s premier solution provider in terms of drinking water treatment. Supported by the NSERC Strategic Partnership Grants, the network has 8 Canadian universities working with 30 partner organizations on 18 research projects. Currently, the LCML is responsible for a Res’Eau-WaterNET project related to arsenic and manganese risk assessment in the drinking water system of the City of White Rock. Although the City’s water is safe and meets Health Canada’s Guidelines for Canadian Drinking Water Quality (GCDWQ), the City began work towards addressing the naturally occurring arsenic and manganese by looking at building treatment processes. Pilot-scale experiments have been performed to investigate effects of different water treatment technologies on contaminants removal. The outcomes of this project can provide useful information to help the City’s Water Utility select suitable drinking water treatment approach.

Res’Eau-WaterNET is the Natural Sciences and Engineering Research Council of Canada’s (NSERC) funded program to solve water problems in small systems. The network has 8 Canadian universities working with 18 world-class scientists and supported by more than 100 students and post-doctoral fellows. Van Anda Improvement District(VAID) is a small community of 291 people located on Texada Island, on the coast of British Columbia. VAID’s drinking water comes from Priest Lake that has a high dissolved organic carbon concentration. The district plans to improve the water systems in terms of water supply and treatment. LCML is currently working with VAID on the improving the community’s existing water system, this will ensure that a good quality of water is being delivered to the consumers along with reasonable flow and pressure.

The Sustainable Water-Energy Nexus for Urban Neighborhood Development project is a success story which demonstrates the use of sustainability principles and engineering knowledge in urban planning. This research endeavour was a three-year collaboration between the Life Cycle Management (LCM) Laboratory of the University of British Columbia, District or Peachland, BC, New Monaco Enterprise Corporation, Urban Systems, and WSP group. The LCM researchers worked to develop decision making frameworks and tools to support local authorities, community developers, and other decision makers in their urban development efforts. The team focused on the water and energy supply, public infrastructure, and residential neighbourhoods on an upcoming neighbourhood in Okanagan, British Columbia (BC), Canada. User-friendly tools were developed using multi-criteria decision making (MCDM) methods to identify the most suitable technologies, systems, and growth options for neighbourhood communities. The tools include the FitWater tool (assessing wastewater treatment methods), Water-Energy Nexus tool (developing alternative scenarios and selecting and optimum combination of community water and energy features), Neighbourhood Sustainability Assessment tool (Evaluating neighbourhood sustainability in project planning and design phase), Green Proforma tool (sustainability assessment in roadway development), and a framework for assessing and selecting the best clean energy options for the region. Best management practices and implementation guidelines were proposed, and interactive workshops were conducted with the participation of local governments and industry partners to present the developed tool packages to them. These tools are expected to enable informed decision making backed up with scientific evidence, so that the proposed development project are environmentally conscious, economically sound, and socially responsible.
