Drinking Water Treatment Process
Most drinking water comes from a surface water source, such as a lake or river, or a groundwater source, such as a well or spring. This water requires treatment before it can be safely consumed; the level to which the water is treated depends on the source of the water and also on federal regulations. In the United States, for example, the Safe Drinking Water Act was created by the Environmental ...
