Water is the most important in shaping the land and regulating the climate. It is one of the most im-portant compounds that profoundly influence life. People on globe are under tremendous threat due to undesiredchanges in the physical, chemical and biological characteristics of air, water and soil. Due to increased human popu-lation, industrialization, use of fertilizers and man-made activity water is highly polluted with different harmful contaminants. Natural water contaminates due to weathering of rocks and leaching of soils, mining processing etc. It is necessary that the quality of drinking water should be checked at regular time interval, because due to use of contaminated drinking water, human population suffers from varied of water borne diseases. The availability of good quality water is an indispensable feature for preventing diseases and improving quality of life. It is necessary to know details about different physico-chemical parameters such as colour,temperature, acidity, hardness, pH, sulphate, chloride, DO, BOD, COD, alkalinity used for testing of water quality. Heavy metals such as Pb, Cr, Fe, Hg etc. are of special concern because they produce water or chronic poisoning in aquatic animals. Some water analysis reports with physico-chemical parameters have been given for the exploring parameter study. Guidelines of differ-ent physico-chemical parameters also have been given for comparing the value of real water sample.
