ABSTRACT : Bhopal is the capital of the state of Madhya Pradesh which is undergoing fast rate of urban
development and industrialization with the increase in population growth. This has brought about an adverse
impact on the available precious water resources. The Kerwa dam is a used as a source of irrigation and drinking
water and as a sink for domestic and agricultural waste water.The present study was conducted to assess the
physicochemical variation in water of Kerwa dam at Bhopal. An assessment of various physicochemicalcharacteristics
of water such as pH, temperature, DO, Hardness, Phosphate, Sulphate, Nitrate, and COD was carriedfor a period
of one yearin (Nov. 2010-Oct. 2011) atfive sites of dam to know the pollution status. In the present study all the
parameters such as TDS, pH, alkalinity, total hardness, chloride, Sulphate, nitrate, and fluoride were found to be
with in the permissible limits, while COD and faecal coliform count was found to be beyond the limit in all the
samples. Thus, this water body is not suitable for drinking purpose, so possible remedial method should be
adopted for this water resource. As the TDS and EC values are within the limit therefore the water of this dam
can be used for irrigation purpose.Statistical analysis among various physicochemical parameters was also carried
out. Total hardness shows positive correlation with chloride, sulphate, and nitrate.
