Abstract: Water quality parameters of four streams (Nala) in the Dhatav Industrial area in Raigad District of Maharashtra were assessed during the period of December 2009 to November 2010. These Nala’s joins to Kundalika river which flows across the Roha city and nearby villages. The seasonal variation in the quality of water was observed. The depletion of DO is more in rainy season than the summer season. The COD of Nala -1 was higher in rainy season. Turbidity of samples was comparatively low however some of the samples were colored. Hardness of the samples was in the range from 32 to 420 ppm. The pollution of Kundalika river water mostly related with the quantity of pollutants released through these Nala. Hence, the Nala – 1 is comparatively adding more waste water in river.
