The information system contains physical and chemical water quality variables originating from monitoring programmes carried out by the 13 regional environmental centres and supervised laboratories. Frequent annual monitoring programmes include about 5,000 sampling sites. In addition, data have been collected on a non-frequent basis from many other sites. In spring 2004, the information system contained more than 20 million analyses from 2 million samples and over 61,000 sampling sites. Water quality data from about 60,000 samples are added to the system annually. The information system is mainly used by environmental authorities and research institutes for water quality reports and scientific studies. About one third of the data is coastal, the rest inland.
