Abstract
Fifteen ground water samples (represented by S-1 to S-15) were collected from different locations of Imphal East district of Manipur during post-monsoon of 2014. They were analyzed for physico-chemical parameters like temperature, pH, TDS (total dissolved solids), electrical conductivity (EC), total alkalinity (TA) (and hence CO32- and HCO3-), total hardness (TH), Ca2+, Mg2+, Na+, K+ and Cl−. Only ground waters represented by S-14 (of Achanbigei Makha Leikai) and S-15 (of Achanbigei Mayai Leikai) are found to be fit for drinking purpose from physico-chemical analysis point of view. However, ground waters represented by S-1 to S-13 may also be used for drinking purpose in absence of alternate sources and further it is necessary to treat them so as to keep high values of total alkalinity (for S-1 to S-13) and total hardness value for S-3 within acceptable limit (200 mg/L) of BIS standard for drinking water. All the fifteen ground waters are fit for other domestic purposes also. Besides these, all the fifteen ground waters (S-1 to S-15) are fit for irrigation purpose also.
