New water quality standards proposed by the EU Water Framework Directive (WFD) for metals that are ‘specific or other polluting’ substances form the background to this project, whose purposes are two-fold: to compare natural concentrations of metals in UK waters with the proposed standards; and to establish what this entails for the ‘added risk’ approach to water quality assessment advocated by the WFD. This report then makes a series of recommendations based on the consequences of applying these standards to the UK regulatory regime.
