The overall aim of this work is to extend the knowledge of Urban Diffuse Pollution (UDP) and to assess the effectiveness of available remediation solutions in a confined urban context, where disruption from retrofitting proprietary treatment systems and products (PTS) to existing infrastructure causes major difficulties. The research presented addresses the quantification and remediation of UDP across a study area of the River Douglas in Wigan in the North of England. This study has involved an extensive programme of water quality sampling which has allowed micro-level changes in pollutant concentration to be observed as a result of weather event based urban runoff and enabling diffuse pollutants to be quantified. Following this the study goes on to suggest solutions to remediate sources of UDP exploring the use of vortex separation as a tool to treat polluting surface water drains. It provides performance data on several available PTS some of which were installed in outfalls into the study area in the River Douglas. These systems were monitored and further water quality data has allowed the quantification of the effectiveness in pollutant removal of different PTS. The study identifies the significant contribution of urban areas to diffuse pollution of river water and shows that similar studies need to become widespread if the problem of UDP is to be effectively addressed. Based on the significant contribution to knowledge in terms of the new water quality data generated both in relation to river water quality and treatment products and systems, a series of practical recommendations are proposed in relation to the identification and remediation of urban diffuse pollution.
