Access to clean and safe water is a human need and is a right. However, for over 2 billion people, this simply is not the case. What’s worse is that in countries that have enjoyed the luxury of treated water, there is a troubling trend. From boil water orders to breaks in the system to massive outbreaks, our water supply is at risk. On this week’s show, we’re going to explore why we should be worried about our water.

We first talk with Natalie Hull, an assistant professor of civil, environmental and geodetic engineering at the Ohio State University. Her work has explored the risks to the domestic water supply and we hear of the various factors involved such as increased pollution, climate change, and the water pipeline microbiome. We also learn how the situation might be improved by changing our focus from the water treatment plant to our taps.

One way to improve water safety particularly from microbial pathogens is to use ultraviolet light, which is known to kill microorganisms. It can be used both at the treatment facility as well as in the home. We continue the conversation with Dr. Hull and venture into her research on the use of UV light to improve water safety. According to her findings, we may be able to keep our water safe without overburdening our city and home budgets.

In our SASS Class, we take a wider approach to water safety with our guest teacher, Amy Greer. She’s a Tier 2 Canada Research Chair in population disease modelling and an associate professor in the Department of Population Medicine at the Ontario Veterinary College of the University of Guelph. She has looked at the various factors involved in keeping water safe and as you’ll hear, it comes down to an overarching goal known as One Health. From animals to climate to human activities, there are numerous ways water can become undrinkable and only by understanding all the parameters can we find ways to ensure we have access to water we can drink.
