Part of Speech: adj.
Quotation: Water pollution can come from what scientists call point and non-point sources. Point sources are obvious, like industry and wastewater treatment facilities. Non-point sources are harder to identify, like storm water run-off, which can contain pollutants from a variety of hard to track sources such as lawn fertilizers, farm run-off, car washing, and resident bird and animal populations.
