The term point source means discernible, defined or confined and discreet. A point-source pollutant is one that reaches water from a single pipeline or channel, such as a sewage discharge or outfall pipe. In contrast, nonpoint source pollution originates over a broad area. The term point source is also defined very broadly in the Clean Water Act and it has been through 25 years of litigation.
