Abstract

In major parts of the world, Surface and ground water are the reliable sources for various purposes. Fluoride is often called a double-edged sword has a great impact on human health. When fluoride is present in optimal concentrations (0.5-1.0 mg/l) in water, it is beneficial for calcification of dental enamel, especially for children below eight years of age, where as in higher dosages causes’ dental and skeletal fluorosis. This project utilized a device called Akvo Caddisfly, which is affordable, portable, and gives instant results. The caddisfly is composed of android app, coupled with a mixing chamber. It uses the phone’s camera sensor and pre-determined calibration curve to detect color changes obtained from mixing of the reagent with the contaminated sample. To determine fluoride content in water samples, Zirconium Xylenol orange reagent was used. Samples around 240 were collected from different water sources of high Fluoride prone region of Nalgonda District, Telangana State, India, tested with fluoride sensing mobile application. For cross-checking the standardization of Akvo Caddisfly device, A few resulted values are compared with the values of standardized testing method called Ion Selective Electrode Method. The results showed slight deviation in values. Thus, the Akvo Caddisfly is a highly suitable device in the real field for testing water with accuracy which enables to access with great ease, helps people to understand their standards of lives and develops potential to adopt changes.
