The data and information were collected from respondents in six village related to aworeness and incidence of fluorosis, awareness regarding the CECOEDECON project and the use and effectiveness of domestic defluoridation technology. Analysis of collected data revealed that level of awareness was highest (68%) among the respondents of Barkheda and Yarlipura villages where the project was withdrawn in 1998. It was observed that the level of awareness decreased over time and it was found lowest in the villages where project was withdrawn in 1996. About 87% of the respondents reported that most of the women are members of the Mahila Mandal started under CECOEDECON project. Some of the respondents (38%) mentioned that they were experiencing problems after the withdrawal of project teams.

Activated alumina was modified by coating it with Iron oxide to make it suitable for As (III) adsorption. Iron oxide coated activated alumina was tested for its effectiveness as an adsorbent for As (III). The As (III) adsorption was strongly dependent on pH and a maximum removal of 98% was observed at a pH of 12. The adsorption process followed a first order kinetics. The equilibrium was attained after 8 hours. The kinetic study was carried out with different initial As (III) concentration.
