Aspects of water pollution control of Austrian rivers
Chovanec, A.; Vogel, W. R.; Winkler, G.
A country-wide water quality monitoring system for running waters, which was established in 1991, is one of the key elements of Austrian water management and pollution control. The general principles and features of the monitoring programme are presented here (e.g. design of the monitoring network, sampling, variables, aspects of quality assurance, standardization procedures), and monitoring results (e.g. BOD, AOX, atrazine) are discussed and complemented by those of regional surveys. Thus the main areas affected by water pollution can be defined. The integration of the monitoring programme into a new approach for assessing the ecological capability of rivers is another point of interest. The importance of the application of new bioindication methods (e.g. accumulation of organic compounds in aquatic mosses) for sound water pollution control is also discussed.
