What type of H2O do u use?

Hey y'all I was wondering what kind of water do y'all use, supplements included. Post what you use so I can put it in my book I'm writing.

i have been having nothing but problems with my city water lately so i just purchased a RO system and from talking to many many people on the subject, and doing alot of research on the systems i have come to the conclusion that no one should grow without RO water. Since i have been having problems with my water i have been looking into whats in water that comes from our tap if you live in a city. Im not the smartest person in the world but i know arsenic,nitrates,copper,lead,Chloroethene,Manganese,Trichloroethene,fluoride,Organic Carbon and a bunch of other shit can't be good for you, and if you look it up you will see all the bad shit in ALOT of cities water. shit im starting to think that thats why alot of people get cancer????? ya thats my two cents worth
