The Nonpoint Source Program covers land uses that cause pollution and includes which of the following categories?

• A. Discharges from industrial facilities
• B. Sediments, nutrients, pesticides, organic wastes, livestock wastes, crop debris, oils
• C. Groundwater contamination from point sources
• D. Only erosion control measures

Answer: (B)

Nonpoint source pollution comes from broad land-use activities rather than a single discharge point, and the program targets pollutants that originate from many diffuse sources carried to waterways by runoff and infiltration. The listed pollutants—sediments, nutrients, pesticides, organic wastes, livestock wastes, crop debris, and oils—are the typical nonpoint pollutants associated with farming, urban runoff, construction, and similar land uses. They reflect contaminants that move with water rather than emanating from one identifiable outlet, which is why this option best matches what the Nonpoint Source Program covers. The other choices describe point-source discharges, point-source groundwater contamination, or nonpollutant-focused erosion-control measures, none of which capture the pollutant categories emphasized by the program.
