Very true..... Many years ago, a drought caused me to recognize how bad the city water was. I recall turning on the faucet and not only could I see it, but could smell fuel oil. That's when I started to be very concerned about the drinking water. This reminds me I'm due to changing my RO filters in the house. I need to order filters soon. RO is a good means of removing toxins from the city water. I use to fill up 5 gallon glass jugs with Artesian water. It was cumbersome and a lot of effort. It was the best tasting water though.
