The Clean Water Act requires each state to list its polluted waterbodies and to set priorities for cleaning them up. Waterbodies qualify for the “impaired waters list” when they are too polluted or otherwise degraded to support their designated uses. The impaired waters list is also referred to as the “303(d) list,” named after the section in the Act that requires it.
