Diluted or not it shouldn't be in our drinking water period. I live in NY and have dogs that have gotten cancer from giving them tap water. My dogs now only drink bottled water and there hasn't been a problem in years. Just like the FDA approves a chemical that is used in anti freeze to keep ice cream from freezing solid. So I'm going to eat something that has a slight amount of chemical found in antifreeze? I don't think so. Small amounts of poison ingested time after time can do not good to our bodies. Please be aware. God bless!!
