Living in NYC, it’s from the faucet or bottled water. And on Manitoulin, I know certain rules, such as not drinking from a Manitoulin stream or untested lake or river water, but what about other sources? Not knowing much about water and wanting to learn more, I was delighted to talk to Jeff Wahl of Wahl Water on Manitoulin Island. Jeff has specialized in all kinds of water treatment for more than 20 years.
