NSERC-Strategic project: Protection of Water Consumers by Development of In-situ Monitoring Capabilities for Water Distribution Systems

A contaminant warning system (CWS) with the capability to detect aberrations in drinking water in real, or near real-time, represents significant value for protection of consumers from accidental or intentional contamination of drinking water. A two-tier contaminant warning system (CWS) is being investigated to employ multi-parameter sensor system to achieve the fundamental characteristics of a CWS . CWS consist of an early warning system (EWS), event detection algorithm and a confirmatory system. EWS detects any aberrations in water using multiple sensors such as free chlorine, turbidity, pH, conductivity and non-purgable organic carbon. Aberrations are interpreted and contamination is detected using Bayesian Belief Network. Once a contamination event is detected, an alarm is triggered and a real-time sample is taken for confirmatory analyses such as ATP analysis, micro-fluidic image processing, spectral fluorescence, spectrophotometry, etc. Finally, a multi-stage response procedure is used to identify the origin of contamination in drinking water distribution systems.

Remediation of DDT-contaminated Soil

Soil contamination with persistent pesticides such as DDT is a risk to human and the environment. A surfactant-aided soil washing technique is being investigated as an alternative method for remediation of DDT-contaminated soil of a site at Ontario, Canada. An Ex-situ soil washing method is employed using mixture of non-ionic and anionic surfactants, i.e. Brij 35 and SDBS. The optimized mixture removes 70-80% of DDT and its metabolites from the contaminated soil. As well, various soil washing procedures such as flow-through and mixing systems are being investigated to determine the recipe for pilot-scale tests. The wash-off liquid is dechlorinated using zero-valent iron under anaerobic condition and low pH and/or sorption to activated carbon

A Critical Evaluation of the Appropriateness of Ceramic and BioSand Filters in Rural Cambodia

The United Nations Millennium Development Goal (MDG) #7 -Ensure Environmental Sustainability contains three key targets, one of which is: "halve, by 2015, the proportion of people without sustainable access to safe drinking water and basic sanitation". According to the World Bank, unless significant advances are made in the water and sanitation sector, it is unlikely that Cambodia will meet the MDG target. Household or point of use (POU) water treatment technologies have been identified as successful interventions for providing safe water to rural households. Currently, there are two water treatment technologies that have been widely implemented across Cambodia: ceramic water filters and BioSand filters. Both technologies have proven to reduce diarrheal disease by up to 50%; however, to date there is very little published research that critically evaluates the performance and sustainability of these systems in the field.

The goal of the research was to evaluate these technologies in the context of rural Cambodia. The ceramic and BioSand filters are evaluated on their performance in terms of microbiological and chemical quality of the treated water. In addition, one of the objectives was to investigate the factors that contribute to the long term sustainability of these systems in the field, and to identify factors that influence their long term use. The results are used to provide an overall assessment of the appropriateness of these technologies in rural Cambodia and provide recommendations to aid Non-Governmental Organizations (NGOs) and other groups in the decision process for choosing a point of use water treatment technology for a particular source water quality, and circumstance.
