A Study of the Physico-Chemical and Biological Characteristics of Drinking –Water Quality from Different Points- of- Use in Shillong Polytechnic, Mawlai Kynton Massar and Mawlai Mawdatbaki, Shillong, Meghalaya

Water is the most essential requirement of humans, plants and animals. It is the life blood of man, without which life on earth will cease to exist. Most human activities involve the use of water in one way or other. Although the surface of our planet is nearly 71% water, only 3% of it is fresh [1,2]. Of these 3% about 75% is tied up in glaciers and polar icebergs, 24% in groundwater and 1% is available in the form of fresh water in rivers, lakes and ponds suitable for human consumption [3-5]. Out of all water resource, groundwater is one of the important drinking water resources [6,7].
