Abstract Underground waters of the semi-arid tract of Agra were examined for their F concentration and other chemical constituents. The F concentration in waters varied from 0.2 to 3.2 mg l −1 and 56% of the waters contained injurious concentration of F for drinking water. However, these waters were not harmful for most crops with respect to F concentration. Fluoride concentration was not correlated with EC, B and Na concentration of groundwaters.
