| description | Argues that excessive fluorides in groundwater are a serious water
quality problem in some parts of Sri Lanka. The incidence of dental
fluorosis shows a high correlation with the presence of groundwater in
certain areas. Tube wells constructed in various rock types have shown
different fluoride concentrations, possibly due to the different mineral
constituents in these rocks and their relative capability of releasing
fluoride ions into groundwater. It has been observed that the tube wells
located in the dry zone have higher fluoride concentrations than those
in the wet zone. The fluoride contents of groundwater show an inverse
relationship with average yields of the tube wells, indicating the
inverse relationship of aquifer permeability to the fluoride content in
groundwater. |
