Abstract
The paper deals with the relationship between soil chemistry, surface & sub-surface water chemistry and geology of the Kuhi mineral belt, Nagpur district, Maharashtra. Water samples were collected from shallow aquifers and surface water and were analyzed for major ions and trace elements. The study was also made to assess the suitability of these waters for irrigation use. Topsoil samples were collected and analyzed for trace elements. Chemical analysis shows that majority of the groundwater of the area is calcium bicarbonate type. Statistical analysis determines high positive correlation values for cobalt and nickel in water as well as soil. The spatial distribution of Co, Ni, in soil and Co, Ni and Pb in groundwater are nearly similar. Water samples, 7 out of 46 were found un-suitable for irrigation use based on RSC, salinity hazard and Boron concentration parameters. The surface water samples of Nag River show decreasing concentration of major ions and trace elements along the flow. Based on field and laboratory observations it was found that the Nag River water is suitable for irrigation even though it contains high detergents with objectionable colour, taste and odour.
