Drinking Water At Sports Events

My child takes Tae Kwon Do. He is actually really good. Well, I am on the parents team that manages the tournaments. I came up with the idea of changing how the kids drink water at the tournaments. Both parents and the kids agree that drinking from the water fountains is no good, since the water has all sorts of bad stuff. But with the new green age upon us, plastic water bottles are becoming an issue. So I talked them into using water filters! Now we fill up 5 gallons of water with a tap and they drink that instead of buying bottle water!
