Abstract

In developing and hilly states like Mizoram, there are several mountainous and rural areas where treated water supply is not available for consumption. As it is a must for such areas to rely on water collected from open sources like stream, well and spring nearby; studying the physicochemical and bacteriological condition plays a crucial role. The research involves the study of water samples that were collected from fifteen water stations where the water is utilized as drinking water from the month of January, 2021 to December, 2021. The parameters used for analyzing water samples were Colour, Odour, Temperature, Electrical Conductivity, Turbidity, Total Dissolved Solid, Total Suspended Solid, pH, Dissolved Oxygen, Biological Oxygen Demand, Total Alkalinity, Total Hardness, Chloride, Magnesium, Nitrogen Nitrite, Nitrogen Ammonia, Total Phosphate, Calcium, Sodium, Potassium, Faecal Coliform, Total Coliform. The results from the study were compared with the standard limit set by WHO, BIS, CPCB. The study reveals that all the water quality parameters were within the given standards except for pH, turbidity, Dissolved Oxygen, Nitrogen Ammonia, Total Phosphate, Faecal coliform and Total coliform in certain stations at particular seasons.
