National Drinking Water Clearinghouse (NDWC)


The National Drinking Water Clearinghouse (NDWC) was a public service organization dedicated to helping small communities by collecting, developing, and providing timely information relevant to drinking water issues. NDWC provided free and low-cost publications, products, databases, referrals, and more.

The NDWC was sponsored by the Rural Utilities Service (RUS), a division of the US Department of Agriculture's Rural Development Program. The program served as an extension of RUS's commitment to providing technical assistance to America's small and rural drinking water treatment plants.
