abstract
A total of sixty (60) samples from organized and unorganized sectors were collected in five different districts of the Brahmaputra Valley of Assam. Six (6) samples were collected each from organized and unorganized farms from one district. The water samples were assessed with the help of water testing kit (Jaltara water testing kit-TARA life sustainability Solution Private Limited, New Delhi, India). The results of the chemical parameters namely pH, TDS, total hardness, arsenic chloride, fluoride, nitrate and sulfate showed that the concentration of these parameters were below or within the guideline limit. It can be concluded that the water samples were found to be safe for consumption while the iron concentration was higher both in the organized and unorganized sectors of all the selected districts where Kamrup (R) and Nagaon bear the highest concentration among all the selected districts.
