Detail Assessment of Physico-Chemical Properties of Perennial Spring Water within Aizawl City, Mizoram

Water quality is the term used to express the suitability of water to sustain various uses or processes. Earth’s water resources, including rivers, lakes, oceans, and underground aquifers, are under stress in many regions. Humans need water for drinking, sanitation, agriculture and industry; and contaminated water can spread illness and disease vectors, so clean water quality is both an environmental and a public health issue. Nowadays fresh water depend solely on letter physico chemical conditions. Analysis of physico chemical parameters of water is therefore essential, as it has great bearing on the explanation of metabolism of the aquatic ecosystem. So five perennial spring water sites were selected for sampling and analysis where most of the local people at the nearby locality consume the water for different household purposes in the north, east, west, south and central zone of Aizawl city. Six physico-chemical properties were selected for determining the quality of the water. Acidity was found highest in west and north zone and was minimum at the central zone of Aizawl. It was observed that water in all sites were highly turbid during the month of July 2017 and was most turbid in the north zone where the spring water in this area remain unprotected. The maximum dissolved oxygen value was found in the west zone on February 2017 throughout the sampling period where Biological Oxygen Demand was found to be highest in the north zone of Aizawl during the month of July 2017.
