The aim of the study was to characterize the main trends in the development of citizen science (CS), which has been attracting growing interest from society since the beginning of the 21st century, which is associated with the development of digital tech nologies, the ability to connect to the Internet. According to the Oxford Dictionary, "Citizenship Science is the collection and analysis of data related to the natural world by members of the general public, usually as part of a collaborative project with professional sci entists". This movement has a significant activity in the countries of Western Europe, the USA, Australia, and in the last decade in Chin a. An analysis of completed projects shows that citizen science has the greatest impact on research in the field of biology, ecology, and solutions to environmental problems and is mainly used for collecting and classifying data. The accuracy of the data obtained b y CS representatives depends on the proper organization of research and requires constant monitoring and cooperation with profession al scientists. Citizens" motivation to participate in research can also influence the results of CS projects. Three general aspect s are highlighted as motivation for participation in CS: a) &raising the individual scientific and educational level and the desire to increase public awareness; b) filling gaps in government monitoring and identifying local problems; c) harnessing scientific knowledge t o inform policymakers and decision-ma&kers and ensuring consistency of actions at different scales. An important area of research in citizen science is monitoring the quality of water in water bodies, as evidenced by more than 800 works published during 2010-2020. In periodicals index&ed by the Web of Science. It is relevant to involve representatives of ci tizen science in solving the tasks facing SDG 6 "Clean water and adequate sanitation", one of the 17 global goals that were adopted a t the UN Summit on Sustainable Developme&nt (2015) for the period 2015-2030. The participation of citizen science can be significant i n the context of SDG 6.3.2 "Identifying the proportion of water bodies with good water quality", as these studies relate to the monit oring of water bodie&s at the community level. The FreshWater Watch program, launched in 2012, is based on continuous monitoring of freshwater bodies. The program has both a global and a local level. Global level - citizen scientists in different countries pa rticipatin&g in the program work according to the same methods and register a common set of parameters that are loaded into the same databas e. Local level - working with local groups and scientists who have scientific questions about their specific water bod&ies. Thus, u sing global approaches, it is possible to answer local questions about water quality and the state of ecosystems. In Ukraine, the situation with citizen science is fundamentally different from that described above. There is no citizen &scienc e in the same form as in the countries of Western Europe, North America, Australia and East Asia in Ukraine. This is connected bo th with the general economic situation of the country and, accordingly, the constant reduction of scientific in&stitutions, a decre ase in the interest of citizens in science, and with moral and ethical aspects (from the skepticism of professional Ukrainian scientis ts regarding the activities of representatives of citizen science to the unwillingness of bro&ad strata of citizens to spend their time on work in CS projects).But on Facebook (FB) there are groups of biological, hydrological and geological orientation in Ukraine, w hich have their own sites in FB and carry out certain work.Ukraine"s inte&gration into the structure of the European Union will contr ibute to the emergence of new opportunities for further development of citizen society, including participation in citizen science pr ojects.
