Abstract:
A survey was conducted during pre-monsoon season of the year 2017 in Chittorgarh district of Rajasthan to assess the groundwater quality and it was found that the well depth of groundwater varied from 7.00 m to 30.20 m with an average value of 16.69 m while groundwater levels of Chittorgarh district varied from 3.00 m to 25.00 m with an average value of 12.34 m. TDS of groundwater of Chittorgarh district varied from 110 to 2920 ppm with a mean value of 600 ppm. pH of groundwater found in the range of 7.00 to 9.40 with mean value of 7.70. The electrical conductivity of groundwater varied from 0.17 to 4.56 dSm^-1 with a mean value of 0.94 dSm^-1. Based on the electrical conductivity of groundwater 1.49% groundwater sample falls under low salinity class (C₁), 44.03% samples falls under medium salinity class (C₂), 50.00% groundwater samples falls under high salinity class (C₃) and 4.48% falls under very high salinity class (C₄). Concentration of cations Ca²⁺, Mg²⁺, Na⁺ and K⁺ were found 0.20 to 6.20, 0.60 to 7.20, 0.25 to 28.52 and 0.10 to 3.60 meL^-1, respectively. The concentration of anions CO₃^2-, HCO₃^-, Cl^- and SO₄^2- were recorded in the range of 0.00 to 4.80, 0.40 to 12.20, 1.00 to 24.00 and 0.15 to 4.50 meL^-1, respectively. Hence, it is concluded that the nature of groundwater of Chittorgarh district is Na-Mg-Ca and Cl-HCO₃-SO₄ type.
