The groundwater present in the hard rock region of the dry zone of Sri Lanka is made up of the shallow 'Regolith Aquifer' and the deeper fracture zone aquifer is now clearly recognized. However, up to now no study had been carried out or reported in this country on the dynamic nature of this shallow regolith aquifer. This is the very first study carried out and reported in this regard. As part of the study, the impact of the Mau Ara trans-basin canal on the groundwater conditions below the area of influence of this trans-basin feeder canal has also been examined.

In India, high fluoride concentration in groundwater (greater than 1 mg/l) is widespread in the arid to semi-arid western states of Rajasthan and Gujarat and in the southern states of Andhra Pradesh, Karnataka and Tamil Nadu. A field research study conducted at six areas severely affected by fluorosis shows that affordability of safer drinking water is related to higher income level, and that the severity of fluorosis affliction is higher for lower income levels. The cost incurred on medicines and loss of wages is a significant proportion of the earnings and has a general debilitating impact on the affected families. As compared with fluorosis, the skin afflictions of arsenicosis carry greater social stigma and patients incur higher costs. In Nadia district of West Bengal, the impacts of arsenic contamination are more severe with increasing age. Cumulatively, over the entire afflicted population, both fluoride and arsenic contamination have a high cost on society and addressing the problem would require more attention from government agencies and society apart from individual awareness.

The study was conducted to assess caries and developmental defects of enamel in relation to fluoride levels in drinking water and the association between caries experience and the severity of diffuse opacities in children living in Uda Walawe, an area with varying concentrations of fluoride in drinking water in Sri Lanka. A total of 518 14-year-old children who were lifelong residents in this area were examined for dental caries and developmental defects of enamel. But the present analysis is confined to 486 children from whom drinking water samples were collected. The prevalence of enamel defects and diffuse opacities ranged from 27 to 57% while the prevalence of caries ranged from 18 to 29% in the different fluoride exposure groups. The prevalence of enamel defects increased significantly with the increase in the fluoride level in drinking water. Both the caries prevalence and the mean caries experience were significantly higher in children with diffuse opacities than in those without in the group consuming water containing >0.70 mg/l of fluoride. The association between dental caries and the severity of diffuse opacities was also significant only in this group. Children with the mildest form of opacities (DDE scores 3 and 4) had the lowest DMFS (0.25 +/- 0.7), and the highest DMFS (1.1 +/- 1.7) was found in those with the most severe form of opacities (DDE score 6). In conclusion, the relationship that was observed in this study between fluoride levels in drinking water, diffuse opacities and caries suggests that the appropriate level of fluoride in drinking water for arid areas of Sri Lanka is around 0.3 mg/l. Also individuals with severe forms of enamel defects in high-fluoride areas are susceptible to dental caries.
