This guidance focuses on the contribution of the point sources to the widespread phosphorus enrichment of rivers in England and elsewhere in the UK. In particular, it examines the role of phosphorus stripping in reducing ecological risk from elevated phosphorus levels.The document is relevant to all those who have an interest in the behaviour, ecological influence, and control of phosphorus in riverine ecosystems. It provides information on a range of issues, including phosphorus behaviour in the environment, mechanisms of ecological impact, the role of point and diffuse sources, targets for phosphorus levels in rivers, techniques and efficacy of phosphorus stripping, and the planning of stripping programmes. It should help to provide an objective basis for developing phosphorus control programmes for point source.
