The National Rivers Authority (NRA) uses various schcmes for the assessment of river water quality. These procedures include periodic chemical and biological surveys, and reporting upon compliance with the requirements of EC Directives. The Surface Waters (River Ecosystem) (Classification) Regulations 1994 introduce a component of a new scheme, the purpose of which is to place water quality targets on a statutory footing. This new scheme is known as the statutory water quality objectives (WQO) scheme. The Water Resources Act 1991 contains provision to develop new schemes for the classification of Controlled Waters. On the basis of these classification schcmcs, the Act empowers the Secretaries of State for the Environment and for Wales to set statutory WQOs for specific stretches of water in order to secure specific water quality standards for them by given dates.
