The manual includes brief information on sources of water pollution in water bodies and recommendations on how to create an initiative group for observations. This is a set of methods for public research of water bodies of the Baltic Sea, as well as a description of the methodology for conducting
hydrochemical studies of surface waters, which is available to a wide range
of public observers/river watchers.
