The purpose of this report is to review the role of nitrogen (N) and phosphorus (P) in the eutrophication of surface water. The work was required by Water Framework Directive 2000/60/ES as part of investigating excessive nutrient enrichment. This report reviews nutrient inputs to surface water; the role of nutrients in the eutrophication of surface water; the response of biota to nutrient enrichment; monitoring of changes due to eutrophication and the management of eutrophication. Monitoring of surface water bodies has been provided in terms of requirements of the Water Framework Directive. With regards of international and national legislative for the ecological status assessment ecological potential, chemical status, biological quality elements, supporting physical-chemical and hydro-morphological quality elements as well as the specific substances have been investigated. The aim of this contribution was to analyse eutrophication problem, factors affecting this process, its consequences and possibilities of prevention. The partial aim was to evaluate eutrophication state of surface water in itn ostrov channel network following the assessment physical-chemical and microbiological indicators in monitored period.
