This paper presents the results of evaluating the environmental risk induced by the activity of non-compliant municipal landfills of class "B", in a period of over four decades. Storage locations analyzed presents a number of particularities: is situated in a hilly area, with an energy of about 40 m of relief, marked by the presence of a stream with flow influenced by precipitations, in proximity of an emissary Slatina rivulet. Starting from the principle that the environmental risk is defined as the product between the probability of appearance of some threats to the quality of the components of the environment and their consequences (severity of the effects), the base of investigations was relationship source-path-receiver. Assessment hazard and effects was realized on the basis of the results of quality investigations the soil, groundwater, and leachate transported by stream and surface water flood thus highlighting the sources of danger and their route of transmission. Ecotoxicological characterizations for surface water and leachate, to taken in consideration the results of acute lethal toxicity tests performed in laboratory on fresh water fishes (Carasius auratus) and acute immobilization of water flea Daphnia Magna Status species (Cladocera crustaceans). The studies were conducted in accordance with the methods OECD 203 and 202 published in Regulation (EC) 440/2008 with any future changes in Regulation (EC) 761/2009. Quantifying the risk of occurrence of a serious risk underlined induced of the groundwater and surface water – Slatina rivulet. Development of tree chart of the adverse effects allow formulation of the measures necessary to be applied in risk management process in order to eliminate causes of danger and/or restriction of adverse effects generated of the WATER environment component.
