This article discusses combining natural and traditional treatment systems to provide multiple barriers, improve source water quality, minimize treatment costs by lowering chemical doses, and improve finished water quality. Examples of natural treatment systems include natural and man‐made wetlands, tree farms used for landfill leachate, and water moved through soil or aquifers. The article discusses riverbank filtration and aquifer storage and recovery as natural treatment options, along with biological processes, physical processes, and chemical processes. It also discusses how the quantity and quality of water from these systems depends on the hydrology of surface and groundwater sources, such as riverbed infiltration rate and contact time in the soil, and the soil's geology.
