As a missionary, I've heard a lot of debates on water purity in Africa. Here at school we go through training called "Appropriate Technology", or apptech for short. This is how we train nationals in Africa to purify and clean the very water you are talking about. Unfortunately, these methods are long and drawn out, but they do work. The water may not taste very good, but it will be clean. I have used them, and have never gotten sick, even when staying in a wildlife park in Burkina Faso where elephants drank from the same water. All you need are bottles to hold the water, something dark to place them on as you go, sunlight, and filters like coffee filters and/or socks. You have to leave the water on top of the dark thing (whatever you use - we used trashbags) for a few days. I cannot recall the exact amount of time it takes, but I will check and post the actual requirement tomorrow, but it is long. After you've let it get hot for a few days in the sun, put it through the filters. Like I said, it is a drawn out method, and may not be what you're looking for. But, it does work. Others may disagree with me, but I will swear that it works. It just requires patience.
