The paper shows the incorporation of various influencing parameters in water quality. Damodar river is mainly polluted due to mine overburden, fly ash, oil, toxic metals and coal dust, that has been drastically controlled by strict implementation by the Central Pollution Control Board as well as State Pollution Control Board for the effective measures to be taken by the industries and municipal bodies. The study shows the effect of biological parameters like – Biological Oxygen Demand (BOD =Exposure Factor 24.61), Most Probable Number (MPN =Exposure Factor 32.42) and Total Kjeldahl Nitrogen (TKN = Exposure Factor 31) mainly responsible for the river pollution. Similarly, Surrogate Number Level of exposure Factor i.e., SNLF for BOD is 24.61, for MPN is 32.42 and for TKN is 31. The above parameters help in deciding mode of Hazard transmission, Condition, Nature of Risk, Consequences, Severity of Risk as per EF, Severity of Risk as per SNLF, Detectability and Risk Classification. The present study will be helpful for industrialists and environmentalists to analyze the hazard transmission and apply the risk control measures.

Keywords: Severity of Risk as per EF, Hazard transmission, Risk control measures
