Which of the following would not be considered a point source pollution contributor?

Point-source pollution comes from a single, identifiable source, such as a pipe or a concentrated facility. A paper mill, slaughterhouse, and animal feedlot are identifiable sources, while cattle spread across rangeland can contribute diffuse runoff from a broad area. Therefore, cattle on rangeland are not considered a point-source contributor.
