I figure I've spent tons of money on bottled water over the years. The faucet water in my area is always very cloudy and has a strong taste to it, and I will never use it in cooking. However, I might've been able to save a couple grand over the years had I used regular, old faucet water to drink than bottled water. How unsafe is drinking water in the USA, typically? Would it be wise to invest in a faucet water filter?
