Abstract : A study on the quality of drinking water in Darrang District (Assam) and some adjoining areas carried out during 1975-79 has been reported. A total of 1126 water samples (962 treated and 164 untreated) collected from different units/water distribution centres of army interest were analysed. It was observed that the underground waters of six deep tube wells were generally soft, acidic and highly ferruginous in character. All physicochemical constituents excepts the iron content were within the limits as prescribed for drinking purposes by ICMR. Raw waters drawn from deep tube wells and shallow wells were found to have iron content as high as 21.0 ppm and 24.36 ppm respectively. About half of the total treated water samples analysed (484 No out of 962) during the 5-year period contained iron beyond 1.0 ppm.
