River quality water monitoring

Chapter 5. Rivers provide a critical water resource to support a country’s population, agriculture and industry, alongside its precious natural environment. As demand for this finite resource rapidly grows across the planet, it is becoming increasingly vital to address growing pollution problems. Suitable water quality monitoring techniques and new technologies, alongside the latest data interpretation tools and modelling, can provide key information on the sources of pollution to provide the knowledge base to ensure sustainable management in the future. This chapter introduces some useful source apportionment tools and new chemical and biological monitoring techniques, and how they were recently applied to the upper Ganga catchment of India.
