We must address the consequences of both present and future contaminant threats to water catchments if we are to provide action that provide solutions at all levels. The implementation of sensors for monitoring important biological and chemical parameters, through time and space, is the indispensable basis for accurate assessments whilst the deployment of state-of-the-art water treatment technologies for the removal of pollutants will enhance water protection and security. Firstly; improve our ability to determine the presence of pollution in water courses and the development of novel sensing approaches to help reduce or prevent pollution at source. We will do this via; The deployment and implementation of new in situ fluorescence sensors that have been developed by UWE, Bristol and Chelsea Technology Group (CTG) as part of a current NERC Grant (NE/K007572/1).
