Slide 2

Quality and Quantity of Drinking Water is a Major Problem Worldwide, a huge number of individuals kick the bucket every year from tainted drinking water. Amid most recent four years, Canadians confronted a few drinking water catastrophes Walkerton-Seven individuals kicked the bucket and 100s got to be debilitated. Battleford - Many individuals became ill from intestinal malady Each year 1000s of water supplies in Canada give bubble water advisories. Late report says BC has 40% more noteworthy frequencies of water related malady than some other areas in Canada. Lion's share of these issues begin at the source water biological systems and watersheds, yet next to no is done to support water quality at the source. Challenge? To deal with the nature of drinking water under unsustainable land/water-utilize, poor source water, and falling flat foundation.

Slide 3

Why adopt biological community and watershed strategy to maintain spotless and solid water? Since issues begin at the source water biological systems and watersheds. What are the quality and wellbeing pointers of water quality? Pathogenic microorganisms and protozoans-intestinal ailment Excessive supplements and green growth - taste/smell, poisons, cleansing results Harmful chemicals - pesticides, herbicides, metals, anti-infection agents and phamacare items Unfortunately, treatment and purification can't dispose of the greater part of the water quality issues. While sterilization and filtration can be compelling in diminishing danger of pathogens, they deliver cleansing repercussions with huge wellbeing danger and make water supply exceptionally costly and wasteful. Why not create source water administration and security to decrease these dangers, to give solid water, to lessen cost and increment effectiveness?

Slide 4

Poor quality water at the source expands wellbeing danger of drinking water at home. Source Water Quality Bacteria, Algae, Pathogens TOC, DOC, Turbidity, Toxins Coagulation/Flocculation expels colloidal particles by including certain chemicals (coagulants) Sedimentation Floc settles down to the base Storage for sterilization to happen, and for variable water request Disinfection eliminate microbes and different creatures Filtration evacuate particles through channels Disinfection Byproducts shaped amid treatment and cleansing

Slide 5

NSERC-Industry Research Chair Program in Environmental Management of Drinking Water Our Research at UVic at present cover the accompanying particular viewpoints: Watershed forms prompting to supplement, substance, dregs and pathogen stacking to source water. Sea-going procedures controlling source water quality in connection to water level and watershed changes. Biology and source following of pathogens as an element of land-utilize designs. Creation of cancer-causing side effects in savoring water connection to source water. Advancement of GIS and Remote Sensing based models for land-utilize designs and water quality/amount. Displaying waterborne illness in BC utilizing medicinal charging and solution information. Remaking of memorable climatic conditions, arrive/water utilize, water quality, and foodweb changes utilizing dregs sequence. Hg pollution of fish in BC lakes and its wellbeing suggestion *

Slide 6

Ecosystem and watershed forms influence the nature of water at the source and the nature of water at the tap. Arrive utilize exercises and practices - Agriculture - Farming - Waste transfer - Pesticides/Herbicides - Harvesting - Roads & Highways Quality of source water Bacteria, Pathogens, Humic mixes, Pesticides, Herbicides, Heavy metals Quality of drinking water Human wellbeing dangers from pathogens, side effects, metals & contaminants Loading of - Nutrients - Bacteria/Pathogens - Metals/Organics - Humic mixes Aquatic procedures alter the effects of outer stacking

Slide 7

Nutrients (From watershed arrive utilize, dregs and environment) Nutrient-foodweb forms inside source water are basic determinants of water quality and the effect outside stacking of supplements, chemicals & pathogens. Angle Communities Grazers Small & wasteful nibblers Large & effective slow eaters Poor Source water Bacteria/Algae Pathogens

Slide 9

Increasing centralizations of sterilization repercussions (a few of them can create long haul wellbeing issues) Increasing convergences of natural materials in source water, (for example, microbes, green growth, broke up natural carbon) TOC-DBP relationship DOC-DBP relationship Impact of Ozone and UV treatment on DBP development Type and force of sterilization on DBPs Long-term wellbeing effects of source water quality need more consideration.

Taste and Odor in Drinking Water

Slide 15

Emerging advances that could help creating hearty hazard evaluation and administration apparatuses. Source following of pathogens utilizing ribotyping. Source following of supplements utilizing stable isotopes. Foodweb structure (slow eaters in lakes, repositories or streams) to assess the amphibian frameworks capacity to minimize outer contributions of supplements, chemicals and pathogens. GIS and Remote Sensing models measuring supplement, concoction and pathogen stacking to source water. Master framework for ongoing observing and appraisal of water and watershed conditions. Water and watershed administration procedures in light of coordinated master framework. Enhanced open correspondence and training in view of coordinated watershed science.

Slide 16

Tracking the wellsprings of microscopic organisms One of the latest innovation is DNA finger printing to track wellspring of pathogens. This is an innovation that has for quite some time been utilized by sustenance industry. This procedure is equipped for recognizing sources like people, winged animals, untamed life (by sort) and cultivated well evolved creatures.

Slide 19

Application of Medical Billing and Services Data from groups is an effective method for assessing the wellbeing identified with water.

Slide 20

Integrated Technology for Decision Making * Real-time water quality observing and hazard evaluation * Drinking water and watershed Protection * Sustainable Watershed Management * Prediction of pathogens and wellbeing impacts Treatment Distribution Systems Water Quality & Watershed Data Management Simulation of early cautioning Prototype a work in progress in our research facility at the University of Victoria Decision making Expert System

Sooke Lake and the admission tower providing water to Victoria. A 100-year draft in 2000 brought on extreme water deficiency. Serious drawdown like this causes water quality issues by changing the thermal security and supplement discharge from residue to water August, 2001

Slide 24

Seymour Reservoir of Vancouver Water Supply amid October 2002. Overwhelming Consumption and low precipitation amid summer made this notable low level of water. High presentation of silt has brought about to a great degree abnormal amounts of iron and smelling salts in drinking water

Slide 25

What are the quick difficulties for Canadian people group? We have to think past regarding water as the sole arrangement. We should create incorporated water and watershed science connecting source water biological systems to tap to group wellbeing. Coordination science and strategies for best land-and water-utilize rehearses for perfect and solid drinking water will require: Clean Water Policies and Guidelines that go past treatment and cleansing into short-and long haul human and environmen
