Phosphorus Lifecycle Management
ISBN: 1 84057 570 0
Phosphorus is a major reason why UK rivers are not achieving good status under the Water Framework Directive. However, before potentially expensive measures are implemented, the impact of phosphorus on the ecology must be understood. The first phase of this project reviewed the derivation of the phosphorus standard and its justification. Furthermore, to identify suitable measures, where required, it is necessary to identify the main sources of phosphorus to a water body. A series of spreadsheet models was therefore developed to quantify phosphorus sources to water and the main outcome from the project was a fully operational conceptual lifecycle management tool combining environmental quality (chemistry and ecology) and sustainability (economics and carbon emissions) for a number of possible future scenarios demonstrated for the Wensum catchment; which could form the basis for future river basin planning.
