Jonathan Vandersteen Ph.D., P.Eng., CWS 4 is not sure what he likes better, teaching or water, but is happiest when he is teaching about water. With a background in both Mechanical and Environmental Engineering, he enjoys reading and writing about the technical, political, cultural, social, and environmental aspects of water. In the past, he has investigated water system failures in Northern Ghana, built rainwater collection systems, and studied greywater reuse potential in Guelph, Ontario. Jonathan doesn’t let any of his furnace condensation water go to waste. He is married with chickens.
