Abstract:
People on globe are under tremendous threat due to undesired changes in the physical,
chemical and biological characteristics of water. Due to increased human population,
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 and agro-chemical run off. 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 various 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 physiochemical
parameters such as color, 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 physic-chemical parameters have been given for the
exploring parameter study. Guidelines of different physic-chemical parameters also have
been given for comparing the value of real water sample.
