Abstract
A study on water quality of eutrophied surface water body of Kalna farm as well as ground water quality of the area was done to investigate the level of pollution and contamination that have occurred in these two sources of fresh water systems. Several physicochemical parameters viz., pH, temperature, TDS, turbidity, nitrate nitrogen, phosphate, sodium and potassium content were measured in groundwater samples. For surface water analysis, DO, BOD and COD were mediated to evaluate the pollution load of the surface water bodies surrounding the Kalna farm. Results indicate that all the surface water body was nutrient enriched in terms of sodium (14.73-27.98), potassium (6.59-10.31 mg/L) and phosphate content (0.52-0.73 mg/L) in the water whereas ground water contains more salt content than its surface water counterpart. Surface water body was found to be alkaline in nature (8.09-8.68) whereas ground water was found to be little acidic to neutral range (6.52-7.89). COD values (142-224 mg/L) were found to be higher than BOD values (2.42-5.64 mg/L) indicating presence of higher load of non-biodegradable wastes in the surface water bodies around Kalna farm.
