There are many different types of Water Purification Methods for both residential and industrial capacities from simple boing water to huge filtration plants and this page outlines many of them. We should all be prepared with emergency measures in case of a natural or industrial disaster. We have cited several Do-It-Yourself relatively simple technologies to rely on when necessary or on an ongoing basis. It is wonderful to see all the innovative advancements in this field and as we discover more, we will continue to build this collection of helpful links.
