Factoring Ecological Significance of Sources into Phosphorus Source Apportionment
Models describing the relative contributions of phosphorus (P) from different sources to water bodies (source apportionment) are key tools in determining priorities for mitigation strategies within the River Basin Management Planning process under the Water Framework Directive (WFD). SEPA have made use of a Diffuse Pollution Screening Tool (DSPT) for quantifying and reporting source apportionment within catchments. However, this methodology is simplistic.
