The growth of population in the District has made the water supply schemes under PHE Deptt and Municipal Board inadequate. Therefore, the major part of population of the District has been compelled to use ground water source like Hand Tube Well, Tara Hand Pump, Singur Hand Pump etc. Various water quality parameters such as Water temperature, pH, Turbidity, Total Solids, Total suspended solids, Total dissolved solids. Chloride, Total Hardness, Calcium, Magnesium, Sulphate, Fluoride, Arsenic, Nitrates, Iron, DO, BOD, EC, Alkalinity, Copper, Zinc, Cadmium, Lead & Nickel have been determined for these water sources by using standard methods. Variation of these parameters with respect to time and place has been found out and difference explained. The results have been compared with the water quality standards to find out the degree of pollution in these water bodies by using statistical methods. Total 25 nos sampling stations were taken into consideration in Nalbari District for three seasons as pre monsoon , monsoon and post monsoon.
