The theoretical basis underlying the development of a series of four independent water quality indices is outlined. The main features of their development are the incorporation of legal water quality standards and criteria and the inclusion of information on potential water use and toxic determinands directly within their structural format. The continuous scale provided by a water quality index allows changes in river water quality to be highlighted. The sub-division of this scale into four water quality to be highlighted. The sub-division of this scale into four water quality and water use categories contains sufficient flexibility to enable information at both government and public levels.
