The development of the general conceptual model has been done for the water bodies as they are defined in the national and European legislation. Specific conceptual models have been derived from the general one for the environmental impact/risk assessment brought by hazardous substances discharged in the sewage systems. The project realized also the automated calculus spread sheets with data for the Olt river (five consecutive monitoring years) and for the sewage system of Bucharest city (two consecutive monitoring years). Procedures and user manual for methodology application have been realized. The methodology is able to assess the increase /decrease of the premises of the negative consequences of pollution and consequently of the environmental risk.en-USRough Set TheoryEcological risk assessmentOlt RiverProject
