But you probably consume some of the following everyday:
hydrofluorosilicic acid, aluminum sulphate, ferric sulphate, ferric chloride, sulphuric acid, sodium hydroxide, hydrochloric acid, sodium hypochlorite, anhydrous ammonia, ammonium hydroxide, Calcium hypochlorite, calcium carbonate, calcium oxide, chlorine, chloramines, orthophosphates and long chain polymers.............(just to name a few)
Have you read the "consumer confidence report" your water utility is required to send to every customer every year? Those are all common chemicals used to treat drinking water.
So you say you only drink bottled water..............they aren't required to test for nor are they regulated for most limits your water supplier must meet. Heck, a lot of bottled water won't even pass a bacterial test.
