forWater: NSERC Network for Forested Drinking Water Source Protection Technologies

2017/18-2019/20 • $3,058,750 • PI,CO
Drinking water is one of society's most critical water needs and delivery of safe drinking water-security-is anational strategic priority. Most Canadians are just becoming aware how fragile this essential resource is andthe potentially catastrophic effects climate change and high energy costs...

Optimizing drinking water treatment in response to variable source water quality in Calgary, Alberta: integrating source characterization and process design

2015/16-2019/20 • $651,676 • PI,CO
The drinking water for at least 58% of the largest urban communities in Canada and 66% of American water supplies originates from forested watersheds. The health of Canada's forests and the waters they supply is threatened by severe wildfires (which are increasing in part because of climate...

Identifying critical operational control points and strategies to minimize microbial risk during drinking water treatment

2017/18-2019/20 • $276,924 • PI,CO
Protozoan pathogens remain a significant public health threat associated with the provision of safe drinking water. Climate change is expected to exacerbate these risks due to increased frequency and intensity of extreme weather events. Most drinking water utilities reliant on surface water in...

Drinking Water Security and Climate Change Adaptation in Canada: Evaluating Forest Management and Disturbance Impacts on Treatability

2016/17-2019/20 • $168,000 • PI
The drinking water for more than 58% of the largest urban communities in Canada originates in forested watersheds. The health of Canadas forests and the waters they supply is threatened by numerous pressures, including potentially severe threats from climate change that cause increasingly...

Water economics, policy and governance network

2011/12-2018/19 • $2,311,283 • CO
CHALLENGES. Water resources in Canada face a number of serious challenges. The demand-supply balance is worsening. Income and population growth and rising international demands for Canada's natural resources lead to growing demand for water while climate change and pollution levels reduce the...

A novel monitoring and decision support system to manage water loss in urban water distribution systems

2015/16-2017/18 • $503,448 • PI,CO
Loss of water in urban water distribution systems is one of the major issues facing municipalities today. During the winter of 2015, the City of Guelph, Ontario, experienced nearly 30 pipe bursts and this number is expected to be over 1000 in the City of Toronto. The February pipe burst in the...

Adenosine Triphosphate as a Signal for Evaluating Microbial Risk from Groundwater Supplies

2016/17 • $25,000 • PI
To establish whether groundwater is safe to drink, samples are collected from monitoring wells and tested for avariety of chemicals and indicators of the presence of disease-causing microorganisms (pathogens). In somecases the water at the bottom of the monitoring well may contain water that has...

Understanding pathogen fate and transport in groundwater supplies

2010/11-2015/16 • $150,000 • PI
The contamination of groundwater by microbial contaminants (viruses, bacteria, and protozoa) is currently recognized as one of the most pressing international water supply problems. Hence, a thorough understanding of the mechanisms and factors affecting the fate and transport of microbial...

Using filtration media surface characteristics to improve drinking water treatment

2011/12-2014/15 • $248,210 • PI
For surface drinking water supplies, conventional treatment (coagulation, flocculation, clarification, granular media filtration, and disinfection) remains the most common treatment approach. Although treatment process selection, design, and operation are based on many factors, quality-based...

Improving operational efficiency by real-time in-network distribution system monitoring and hydraulic optimization

2013/14-2014/15 • $94,968 • PI,CO
In Ontario and globally, reduced water losses and energy savings from increased operational efficiency are common goals of drinking water distribution system modeling. Most water utilities have limited capabilities for on-line distribution system monitoring; most often only at the demand metered...

Identifying operational constraints for microcystin destruction by ozonation during drinking water treatment

2013/14 • $25,000 • PI
Algae are present in most water bodies and can produce toxins that are toxic to humans and animals. Waterentering drinking water treatment plants, either from ground water wells or surface water, can contain algae.Many drinking water treatment plants use ozone as a means of eliminating the...

Assessing microbial risk during drinking water treatment: Linking pilot studies to plant performance

2013/14 • $25,000 • PI
In January 2012, Health Canada released its review on the health risks associated with "Enteric Protozoa: Giardia and Cryptosporidium" in drinking water. A key component of this is Quantitative Microbial Risk Assessment (QMRA). Enteric protozoa are specifically of concern when maintaining...

Total organic carbon analyzer and microbial community profiling tools for biological drinking water processes

2010/11 • $74,237 • PI,CO
This funding will be used towards the purchase of a total organic carbon (TOC) analyzer, which measures changes in the organic content of water during drinking water treatment processes and water reuse applications. Organic carbon assessment is particularly important for biological water...
