Document Type: Monograph
The National Rivers Authority (NRA) is a public body whose function it is to protect the water environment. One of our aims is to maintain or improve the quality of rivers by controlling water pollution. The NRA has set water quality targets for all rivers. These targets are known as River Quality Objectives (RQOs). They are used for planning the maintenance and improvement of river quality. RQOs establish a defined level of protection for aquatic life. Achieving these will help to sustain the use of rivers for recreation, fisheries and wildlife, and protect the interests of abstractors. RQOs provide a basis for setting Consents to discharge effluent into rivers, and guide decisions on the NRAs other actions to control and prevent pollution. The water quality classification scheme used to set RQO planning targets is known as the River Ecosystem scheme. The NRA also makes periodic assessments of the quality of rivers in order to report trends over time and across England and Wales. The classification scheme used to report these assessments is known as General Quality Assessment (GQA). Together the River Ecosystem scheme and General Quality Assessment replace the National Water Council (NWC) scheme.
