✦ Synopsis

The toxicity level of underground waters of the semi-arid tract of Bahrain was examined for ( ) the fluoride concentration and other chemical constituents such as sodium absorption ratio SAR , chloride, sulfate, bicarbonate, and boron. The fluoride concentration in waters varied from 0.50 to 1.46 mg/ L and 38% of the waters contained harmful concentrations of fluoride for drinking. However, these waters are not harmful for most crops with respect to fluoride concentration. No significant correlation between fluoride and electrolytic conductance, sodium absorption ratio, or sodium concentrations of the spring and well waters of Bahrain was found. These waters have appreciable salinity but could be used for agricultural purposes, particularly for crops that can tolerate high salinity in water.
