The present project aims at monitoring the physico-chemical and biological quality elements of surface water. The aim of the project is to obtain the information necessary for assessing the quality of surface waters and the status of surface water bodies, for assessing the quality of border water bodies on the basis of the implementation of international bilateral agreements, for obtaining documents for the preparation of future monitoring programmes, for supplementing and validating the validity of procedures for assessing the impact of human activity on surface waters, as well as for the evaluation of long-term changes in natural conditions or for the assessment of changes caused by human activity. The information obtained serves as a basis for assessing the influence of surface water during water management, for the preparation of the water balance and for ensuring the performance of watercourse management and river basin management activities.Monitoring will provide detailed information on the current values of physico-chemical and biological water quality elements at specified abstraction points throughout the territory of the Slovak Republic, with the required monitoring frequency and procedures set out in the Slovak Water Monitoring Framework Programme 2016-2021. In accordance with that document, the measurable indicators of the project are determined by calculating the proportion of works attributable to the Slovak Water Management Company, the State Enterprise, according to its respective competences.
