Physico-chemical investigation of ground water quality of some areas of Imphal east and Imphal west districts during pre-monsoon-1st phase

Abstract

Ten (10) ground water samples were collected from hand pumps of different locations of Imphal East and Imphal West districts during pre-monsoon of 2014 and they were analyzed for physico-chemical parameters such as temperature, pH, TDS (total dissolved solids), electrical conductivity, total alkalinity, 2- 3 CO , - 3 HCO , total hardness, Ca2+ , Mg2+ , Na+ and Cl- . From physico-chemical analyses point of view, the ground waters represented by S-1 to S-5, are found to be fit for drinking purpose as their physico-chemical parameters (mentioned above) values are within desirable limits of BIS standards for drinking water as well as that of WHO. But in case of ground waters represented by S-6 to S-10, their total alkalinity values are found to be beyond the desirable limit (200 mg/L) of BIS standards for drinking water and hence are unsuitable for drinking purpose. So, suitable treatment is required so as to keep the total alkalinity values of these ground waters (S-6 to S-10) within the desirable limit of BIS standards for drinking water. However, as the TDS values of all these water samples, are below 1000 mg/L, all of them are suitable for other domestic purposes. Further, some investigations are necessary so as to check whether toxic/carcinogenic metals such as As, Pb, Cd, Hg etc. are present within the desirable limit or not. Above all, ground waters represented by S-1 to S-10 are found to be fit for irrigation (or agriculture) purposes, as are evident from their electrical conductivity, RSC (residual sodium carbonate) and SAR (sodium adsorption ratio) values
