Abstract: The menace of allege contamination of Romi river is discussed. Many cases of pollution in Romi river could be remedied and the river affected restored to an acceptable state for fishing, irrigation, recreation and domestic use with reasonable expense, if all industries concerned would co-operate. To obtain this cooperation, it is very necessary to understand the situation of the water body and judge it fairly. Much confusion and misunderstanding has arisen in attempts to define the industry responsible for this contamination and the extent of damage to the aquatic organisms, but due to lack of available information on the ecological condition to be defined, in the present study findings and other widely scattered scientific literature by experiment and field work of various agencies brought together covering. (1) The condition which should be maintained to be the recommended standard for drinking water. (2) The specific effects of some physicochemical parameters and some heavy metals which now polluted our streams or rivers. It is hope that use of this information will make possible the definition of undesirable condition of the river with fairness both to the industrialist who discharge the effluent into the water body and to the Romi populace who are entitled to enjoy this same river. The study covered five sampling stations, chosen from the water body stretch. Temperature, pH, Turbidity, Total dissolved Solid (TDS), Biological Oxygen Demand (BOD), Electrical Conductivity (EC), Phosphate, Nitrate and Oil and Grease were analyzed monthly between January, 2015 to May, 2015 using standard method and procedures. The ranges of these factors were found to be comparable to federal ministry of environment (FMEnv) permissible limit for drinking water. The concentration of Turbidity, BOD, Lead, Arsenic, Mercury, Copper, Iron, Manganese and Cadmium were above the federal ministry of environment (FMEnv) permissible limit in station B. DO was within the recommended limit in all stations except station B (effluent discharge point) which was above the standard limit. The level of pollution is more pronounced at sampling point B due to greater EC, BOD and some heavy metals like cadmium, chromium, lead, Arsenic, mercury, copper, iron, manganese, and Nickel which greatly affect the water quality of the river. The study concluded that Romi river water body is slightly polluted due to effluent discharged by the Kaduna refinery (KRPC) and other anthropogenic sources.
