Agricultural runoff and water pollution

Abstract

Agricultural runoff, a nonpoint or diffuse source of water pollution, is receiving increased attention as point sources are being brought under control. Sediment, nutrients, and pesticides are among pollutants of major concern. Livestock operations and croplands are considered principal contributors. Becuase of the diffuse nature of these sources greater technological, economic, and administrative efforts are required to control these sources than point sources. The nature and magnitude of water pollution from agricultural runoff will have to be further investigated through intensive studies and regular monitoring. Awareness of potential problems and effective solutions should be increased through education programs. In British Columbia, the Agricultural Environmental Control program is in operation. In further efforts to control agricultural runoff pollution, pilot improvement schemes should be designed and implemented. In addition, voluntary guidelines and regulatory measures should be reviewed. © 1980 Taylor & Francis Group, LLC.
