Environment committee  Thank you. Good evening, Mr. Chairman and committee members. Thank you for the opportunity to speak to you today and join the conversation regarding fresh water and sustainability. I am a hydrogeologist, and I have spent the past 27 years as a professor—currently at the University of Guelph in water resources engineering, and previously at the University of Waterloo in earth sciences—engaged in teaching and field-based research on groundwater flow systems and the behaviour of contaminants.
