The present study highlights the water quality of Imphal West district, Manipur, India and its suitability for drinking purposes. A total of fifty seven (57) water samples (both surface and groundwater) were collected, during (January –October), 2016 from different locations of Imphal West district, Manipur, and computed the values of WQI of water samples based on physico-chemical parameters like pH, electrical conductivity (EC), total dissolved solids (TDS), turbidity (Turb), dissolved oxygen (DO), total hardness (TH), chloride (Cl-), nitrate (NO3-), total alkalinity (TA), sodium (Na+), potassium (K+), calcium (Ca2+), and magnesium (Mg2+). About 43.85% (25), 29.80% (17) and 15.76% (9) of water samples belong to poor, very poor and unsuitability category of WQI. Some variables like conductivity, total dissolved solids, turbidity, chloride, phosphate and sodium were exceeded their desirable limits for drinking water. This study reveals that the overall water quality of Imphal West district is poor and unsuitable for drinking, and needs proper treatment before consumption.
