Out of the fifty-seven samples, twenty-four (42%) had fluoride concentrations that were higher than the stipulated marginal level (prescribed by the WHO) of 1.5 ppm, fifteen (26%) samples had fluoride concentrations of exactly 1.5 ppm, and thirty-nine (68%) had crossed the safe level of 1 ppm. The samples were again tested in the departmental laboratories at Anantapur and Kurnool and the results were almost identical.

In Chitlamkunta, 65% (11 out of 17 DW) of the drinking water sources had fluoride in excess of the safe level and this included water sources that had fully laid out distribution systems. A social map of the village showing the locations of fluoride-affected water sources (hand pumps and sources of RWS) was presented before the village gram sabha. The reasons for the increase in fluoride concentrations and the adverse impact of drinking water from these sources was also explained in detail through graphs, maps and photographs.
