Hey I'm from Illinois as well. Chicago to be exact.
Yea I'm looking around for a spring source in ILLINOIS.I know there is one , they are always around. Found in many states.
But the best right now is to buy spring bottled water then filter it and restructure it to bring back the life. I'm making excellent clean hydrating water at home. Its like night and day compared to distilled water, IN TASTE TOO.
