Abstract

91 samples were collected for pre monsoon and post monsoon for the analysis. In pre monsoon Total Hardness in the study area varies from 125 to 1328; pH varies from 7.0 to 8.1; Total Dissolved Solids (TDS) varies from 142 mg/l to 2705 mg/l and Electric Conductivity varies from 211.9 mg/l to 4037.3 mg/l. In post monsoon Total hardness of groundwater varies from 132 to 1320; pH varies from 6.5 to 8.1; Total Dissolved Solids (TDS) varies from 332 mg/l to 4404 mg/l and Electric Conductivity varies from 495.5 mg/l to 6573.1 mg/l. In pre monsoon constituents such as Sodium (Na+) varies from 152.8 mg/l to 23 mg/l; Potassium (K+) varies from 57.8 mg/l to 2.1 mg/l; Calcium (Ca+) varies from 82 mg/l to 12 mg/l; Magnesium (Mg+) varies from 362 mg/l to 12 mg/l; Carbonates (CO3-) varies from 96.6 mg/l to 0.2 mg/l); Bi-Carbonates (HCO3+) varies from 1352.4 mg/l to 217.4 mg/l; Nitrates (NO3-) varies from 102 mg/l to 0.4 mg/l; Sulfates (SO4+) varies from 246 mg/l to 4 mg/l; Chlorides (Cl-) varies from 816 mg/l to 36 mg/l; Fluoride (F+) varies from 2.8 mg/l to 0.1 mg/l; iron varies from 2 mg/l to 0.0 mg/l and Alkalinity varies from 680 mg/l to 109 mg/l. In post monsoon constituents such as Sodium (Na+) varies from 296 mg/l to 11 mg/l; Potassium (K+) varies from 250 mg/l to 0.7 mg/l; Calcium (Ca+) varies from 756 mg/l to 16 mg/l; Magnesium (Mg+) varies from 362 mg/l to 5 mg/l; Carbonates (CO3-) varies from 241.5 mg/l to 0.1 mg/l); Bi-Carbonates (HCO3+) varies from 1342.8 mg/l to 237.5 mg/l; Nitrates (NO3-) varies from 42.4 mg/l to 0.9 mg/l; Sulfates (SO4+) varies from 186 mg/l to 1.4 mg/l; Chlorides (Cl-) varies from 201 mg/l to 10.4 mg/l; Fluoride (F+) varies from 5.9 mg/l to 0.1 mg/l; Iron varies from 10 mg/l to 0.0 mg/l and Alkalinity varies from 724 mg/l to 104 mg/l. Piper classification in the pre monsoon revealed 75 % of samples are Magnesium type, 22 % are Calcium, Bi-Carbonate type are 1% and remaining 2 % area Chloride type. There are two types of groundwater facies which exists with 97 % of Calcium and Magnesium facies and 3 % Calcium+Magnesium+ Sodium+ Potasiumfacies. In the post monsoon, 74 % of samples are Magnesium type, 17 % are Calcium, Sodium type are 4%, 2 % area Chloride type and remaining 2% are Potassium type. There are two types of groundwater facies of which 91 % are of Calcium and Magnesium facies and 9 % Calcium+Magnesium+ Sodium+ Potasium facies.
