Dataset description:

The dataset contains data on locations of river monitoring stations of nutrients and hazardous substances inputs to the Baltic Sea reported to the HELCOM Pollution Load Compilation (PLC-water) database. The stations are categorized as hydrological (only flow monitoring) and chemical (monitoring of chemical components). The data is reported to the HELCOM database and quality assured by Contracting Parties to HELCOM in accordance with the HELCOM Guidelines for the annual and periodical compilation and reporting of waterborne pollution inputs to the Baltic Sea (PLC-Water Guidelines).
