CWRDM Newsletter Centre for Water Resources Development and Management MAJOR RESEARCH & CONSULTANCY HIGHLIGHTS Monitoring Mapping and Mitigation of Fluoride in Palakkad including Attappdy of Kerala Fluoride contamination is one of the main problems in Palakkad. UNICEF has sanctioned a project to investigate fluoride and other water quality issues in Palakkad district including Attappady region and also to map the details. As a part of the study, Physico-chemical and bacteriological analysis was done for 245 samples in Palakkad and 117 samples in Attappady as per the standard procedure (APHA 2012). The results show that the Fluoride concentration ranged from 0.02 ppm to 3.3 ppm in the study area. Of the samples analysed, 22% of samples reported fluoride concentration above the limit of 1 mg/l.
Correlation map showing fluoride concentration with depth of wells The depth of the well is found to be negatively correlated with fluoride concentration.
A view of Attappady
The results of the detai-led study carried out in Attappady region shows that the highest fluoride value was reported in Sholayur (3.1 ppm).In Attappady also fluoride concentration decreases with increase in well depth. Sholayur pancha-yath is having campara-tively high concentration of fluoride compared to other two panchayaths.
Between earth and earth's atmosphere, the amount of water remains constant; there is never a drop more, never a drop less. This is a story of circular infinity, of a planet birthing itself. - Linda Hogan
