Abstract: Life is not possible on this planet without water as it is one of the most indispensable resources and is the elixir of life. But due to the rapid growth of population, urbanization and industrialization the water has become polluted. Water is considered as one of the nutrients, although it yields no calories, yet it enters into structural composition of the cell and is an essential component of diet having safe water is a basic human right which must be sufficiently available, accessible, and affordable for personal and domestic use to everyone. This is important for public health and hence, crucial for a developed, stable and prosperous world. Physico- chemical changes may be natural or human induced. Naturally by leaching and percolation toxic metals and chemicals may enter the ground water and contaminate the aquifer. Human induced or anthropogenicaly pesticides and fertilizers which are applied to crop can accumulate and migrate to ground water table. The study was conducted from Feb-2018 to April-2018, and the aim of this study was to examine the levels of some physico-chemical parameters of drinking water of Nuapada district.
