Point source pollutants are discharged from a fixed and stationary location, such as a pipe, channel or ditch. (See also "Nonpoint Source").
Pollutant released from a pipe or discrete conveyance into a water body or a water-course leading to a body of water. e.g. a wastewater treatment plant.
A dust emission source focused at a discrete physical location, such as a mineral crushing unit or a mineral excavator.
A single identifiable source that discharges pollutants into the environment. Examples are smokestacks, sewers, ditches, or pipes. Any pollution with a definable, specific source of origin is referred to as "point-source pollution."
Any discernible, confined or discrete conveyance from which pollutants are or may be discharged, including, but not limited to, any pipe, ditch, channel, tunnel, conduit, well, container, rolling stock, concentrated animal feeding operation or vessel or other floating craft.
A discharge from a facility that has an EPA permit to discharge accepted levels of pollutants into air or water.
A source of acoustic sound waves having definite position but no extension into space. A point source is an ideal, an imaginary single point in space. This imaginary point source provides a good approximation for distances from the point source that are much larger compared to the actual dimensions of the source. A cluster or array of horns and loudspeakers is positioned using this imaginary point in space as a reference for the actual source of the sound. Properly configured the array will perform as a single or point source of sound.
Any stationary source for which individual records are collected and maintained. A facility that releases more than a specified amount of a pollutant.
pollution that enters the water from a single location as a concentrated source
A permanent source of air pollution that can be distinctly identified such as a smokestack.
pollution: Pollution which comes from direct sources, such as a pipe emitting effluent from a waste water treatment facility. Generally, point pollution includes all pollution from which a direct source can be recognized.
A discrete stationary source of pollution, such as a smoke stack.
In the Clean Water Act, it is any discernible, confined, discrete conveyance from which pollutants are or may be discharged.
A point source is an emissions source that can be represented by a point in space, relative to the modeling domain. In SMOKE, a point source is defined by a country, state, and county code, a plant identification code, 1 to 5 additional user-defined attributed (such as stack code, process codes, and a source category code [SCC]). Point sources have other required attributes such as stack parameters.
discharges from stationary locations such as WWTPs, storm sewer outlets and factories. Point source discharges include combined sewer outfalls and storm sewer outfalls.
A single point discharge of, for example, nutrients or sediments rather than run-off from the land
A source of pollutants which may be traced to a discrete point of emission.
Pollution that comes from a discernible, confined, or discrete conveyance such as a pipe, ditch, channel, tunnel, well, or container.
A source of pollution that can be attributed to a specific physical location; an identifiable, end of pipe "point". The vast majority of point source discharges for nutrients are from wastewater treatment plants, although some come from industries.

Point sources can also include pollutant loads contributed by tributaries to the main receiving water stream or river.
A source of pollutants or contaminants that discharges through a pipe or culvert. Point sources, such as an industrial or sewage outfall, are usually readily identified.
A pollution source that has a single point of origin or is introduced into a receiving stream from a specific outlet. Wastewater treatment plant outfalls and CSO points of discharge are typically point sources of pollution.

1. With respect to radiation, a single point in space emitting radiation. The radiation from such a source may be expressed as flux per unit solid angle (W sr−1). 2. In experimental studies of atmospheric turbulence and diffusion, a source of particulate matter from a single fixed point. There are continuous and instantaneous point sources. The analogous concepts of line source and plane source are also frequently encountered. 3. In hydrodynamics, a source of mass, that is, a singular point in the field where the equation of continuity fails.
(Vision Sensing) A light source, such as a spot light, that illuminates a target from one direction. Watch an animation about Geometry of Propagation.

The term is defined very broadly in the Clean Water Act because it has been through 25 years of litigation. It means any discernible, confined and discrete conveyance, such as a pipe, ditch, channel, tunnel, conduit, or container. It also includes boats or other floating craft from which pollutants may be discharged. By law, the term also includes concentrated animal feeding operations, which are places where animals are confined and fed. Agricultural storm water discharges and return flows from irrigated agriculture are not considered "point sources."
Point Source is a company situated in Hamble-le-Rice, United Kingdom. It was founded in 1991 and since has built up a reputation as a key developer of laser and fiber optic systems, specifically singlemode fiber delivery systems. Applications of products include microelectronics, photonics, nanotechnology, biomedicine, microscopy and many other industrial applications.
A point source of pollution is a single identifiable localized source of air, water, thermal, noise or light pollution. A point source has negligible extent, distinguishing it from other pollution source geometries. The sources are called point sources because in mathematical modelling, they can be approximated as a mathematical point to simplify analysis.
