Water samples were collected from nine (9) locations to assess the baseline status of the ground water quality of the study area. The pH values of the collected two water samples from the river Damodar were found 7.5 and 7.3. Values of Dissolved Oxygen were observed (7.1 & 6.9) mg/lit. Total Dissolved Solids were found (193 & 197) mg/lit while values of total Hardness were found (99 & 110) mg/lit. Calcium & Magnesium were found (28 & 34) mg/lit and (7 & 6) mg/lit respectively. Sulphate, Nitrate and Chloride were observed 6 mg/lit, (2.3 & 2.8) mg/lit and (38 & 40) mg/lit respectively. Iron contents were found (0.16 & 0.18) mg/lit in both the samples. The pH values of the collected pond water samples were found in the range of (7.0 - 7.8). Dissolved Oxygen was observed in the ranges of (5.8 - 6.4) mg/lit. Total Dissolved Solids were found in the ranges of (265 - 348) mg/lit while Total Hardness was found in the ranges of (170 - 240) mg/lit. Calcium & Magnesium were found varying in the ranges of (45 -70) mg/lit and (8 - 17) mg/lit respectively. Sulphate, Nitrate and Chloride were observed varying in the ranges of (7 - 15) mg/lit, (3.1 – 5.4) mg/lit and (62 - 86) mg/lit respectively. Values of Iron content were found in the ranges of (0.32-0.54) mg/lit.
