Distribution of Fluoride Content in the Water System around Haldiati-Doboka Areas, Assam

The severity of the impending crisis of potable fresh water and contamination to this life sustaining process by fluoride and arsenic is now a critical concern for the NE-India. Both skeletal and dental fluorosis is reported from the Karbi Anglong and Nowgaon districts of Assam with area and population are 10, 526km2 and 700, 000 respectively. Considering all these an attempt has been made to understand the distribution pattern of fluoride content in the water resources of Karbi Anglong and adjoining Naogaon districts of Assam. The fluoride content in the water samples of the Haldiati-Doboka areas of the Karbi Anglong district, Assam, varies from 0.05mg/L to 3.52mg/L with an average of 1.89mg/L. The study has attributed enough evidence that the water system of the area is not environmentally safe with reference to fluoride content. The arsenic content varies from 3.20-10.60g/L (permissible limit of arsenic is 10g/L, WHO, 1984). Therefore, it can clearly be attributed that the area needs an in-depth investigation in view of the environmental aspects towards improving the quality of life forms around. It is believed that the generated environmental knowledgebase with precision and accuracy will fill up a critical domain in improving the quality of life and people around.
