Abstract: Water is an important constituent for all the living beings. The water quality guidelines provide a limit value for each parameter for drinking water. 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 a necessary feature for preventing diseases and improving quality of life. The different physico-chemical parameters are color, temperature, hardness, turbidity, pH, sulphate, chloride, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD) etc. used for testing of water quality. Heavy metals like Pb, Cr, Fe, Hg etc. are of special concern or chronic poisoning in aquatic animals. This paper summarized the importance of monitoring temperature, turbidity, pH and dissolved oxygen parameters of drinking water and its adverse effect. A lot of drinking water quality parameters are described by world health organization (WHO). It gives the guidelines of parameters for comparing the value of real water sample from that we can decide the quality of water.
