摘要：Ground water quality plays an important role in promoting agricultural production and standard of human health and the sources and causes of ground water pollution are closely associated with human use of water. For many years ground water was thought to be protected from contamination by the layers of rocks and soil that acts as a filter, but contaminants do make their way into the ground water and affect its quality. The present paper deals with the assessment of seasonal variation in ground water and its suitability for drinking purpose. For this purpose major ions were assessed and Water Quality index was calculated for both pre monsoon and post monsoon season. A comparison of ground water quality in relation to drinking water quality standards proves that the ground water quality was altered with respect to parameters such as pH, EC, TDS, Ca2+, Mg2+ and TH showcased higher levels. Similarly WQI calculated for both the seasons ranged to fall in poor to unsuitable category. From the above results it is clear that the ground water of the study area is deteriorated due to paper industry effluents, use of agricultural fertilizers and the local geology and is found unsatisfactory for drinking purpose.
