Effluent from Communal Solid Waste (CSW) landfills poses a serious environmental and social problem for natural watercourses, causing, in combination with other impact factors, the pollution threat for groundwater and the Black Sea coastal line. CSW effluents have complex chemical composition and their impact to the environment is not studied sufficiently. The authors on the Bytha River’s example offer comprehensive approach to establishing systematic monitoring of landfill effluents impact to the natural ecosystems. A key role in this approach is played by integrated methods of biological indication, considering the dynamics of macroinvertibrates biocenoses and the water stream's general toxicity. Ecological state of the water stream sites was evaluated as a whole biotope, which includes wide range of geological, hydrological and physic- chemical aspects and subjected to multilevel pollution.
