Abstract:
Water is one of the precious natural resource and is a vital substance for all natural and anthropogenic activities. Groundwater is considered as the safest source of water and regular assessment of ground water quality is essential for maintaining public health. The present study was conducted to assess seasonal variation in physico-chemical and microbiological quality of ground water at Anthikkad in Thrissur district, Kerala. A total of 80 open well water samples, 40 each during pre-monsoon and post monsoon were collected and analysed for physico-chemical parameters like pH, Total Dissolved Solids (TDS), Dissolved Oxygen (DO), turbidity, Biochemical Oxygen Demand (BOD) and concentration of nitrate. Samples are also analysed for microbiological qualities like Aerobic Plate Count (APC), Coliform count, Escherichia coli and faecal Streptococci count. Significant difference between seasons could be recorded for all parameters investigated except TDS, turbidity and faecal Streptococci count. The results obtained were compared with WHO (2008) and BIS (2012) limits for drinking water.
