Welcome to the United Sludge-Free Alliance web-site.

Our mission is to provide educational information on the issue of sludge using science, history, alternative uses, personal stories, and actions to protect the health and safety of our communities, food, and water.

We are a grass-roots organization of volunteers concerned about the safety of land applied sewage sludge, now referred to as biosolids by the industry promoting this practice.

Our goal with this website is to be a warehouse of information related to the practice of land application of Sewage Sludge. Please browse our pages which we have organized by subject.

You will also find many links to sites that provide additional information collected here. We encourage you to educate yourself about this issue and learn how to make effective changes to protect the land, our food and water sources, and your health.
