This field-kit has been devised for quick and easy estimation of fluoride in ground water for establishing its suitability for drinking purposes. The cost per analysis works out to be nominal. The procedure is as simple as adding a specified amount of FDK reagent to the water sample to be analyzed and identifying the color developed. The color develops instantaneously and the distinction can be made with the naked eye. Water sample can be immediately categorized as being safe, marginal or unsafe for drinking from fluoride point of view. Generally this kit can be an excellent tool for individual/community level identification of safe groundwater sources.
