Until a crisis occurs like the lead-contaminated water in Flint, Michigan, most Americans don’t think much about where their water comes from or if it’s safe.Lake

Mostly, it comes from lakes, rivers and groundwater. Then, the water flows through intake points to a treatment plant, a storage tank, and finally our homes. The most common treatment processes are coagulation and flocculation, sedimentation, filtration and disinfection. But, the treatment processes vary across the U.S. to meet the unique challenges in a specific area. For example, in rural states, nitrate runoff from fertilizers, manure storage and septic systems may seep into rivers and groundwater and can cause serious health problems. Also, in the American West, water can be too salty for drinking and other uses. In this case, reverse osmosis or thermal processes are used to remove the salt. RCAC works with rural water systems in the West to build, improve, finance, operate and manage systems. We also provide low-interest loans to construct, refurbish or replace individual household water well systems – in certain areas.
