  1. Key-note presentation for International Water Association specialist conference on diffuse pollution, Johannesburg, 9-12 August 2005. BJ D’Arcy, T Rosenqvist, G Mitchell, R Kellagher and S Billett INTRODUCTION BMP techniques have been widely deployed to minimise pollution in runoff from urban areas; practical experience in Sweden and parts of the USA goes back decades (see Campbell et al 2004). But how effective have they been in practice at preventing deteriorations in quality as catchments urbanise? And can the technology be successfully retrofitted to restore degraded urban watercourses?
