Shillong city is ever-expanding in all directions leading to population increase and increased utilization of the natural resources, especially the water resource available. To meet the daily requirement of water for domestic as well as commercial demand, the people of Shillong city are increasingly turning their attention to the underground aquifers. However, the water, that is being pumped out is many times being utilized without proper knowledge of its physico-chemical and bacteriological properties. Ignorant on this matter will put the user in a situation where his health may be compromised. This work was initiated with the sole purpose to understand the baseline concentration of different physical, chemical and bacteriological parameters of the groundwater available in and around Shillong city. Thirty-five (35) sampling locations were identified and sampled for three different seasons (winter, pre-monsoon and post-monsoon). The significant observation in this study is that there is a spatial and seasonal variation of all the parameters selected. Concerning pH, iron and total coliform, the majority of the samples reported values that are higher than the prescribed limit for drinking water.
