Assessment of ground water quality of 70 villages in Block Bichpuri of
District Agra was undertaken, and almost all the sources of drinking
water (handpump, openwell and tubewell) were analysed. Of the total 24
3 samples analysed for fluoride, 33.74% were in the range of 0-1.0 mg/
L, 19,34% 1.1-1.5 mg/L, 24.28% 1.6-2.5 mg/L, 17.28% 2.6-5.0 mg/L, and
5.35% above 5.0 mg/L (mean 2.06 mg/L). Significant correlations were o
bserved among various parameters, viz., pH, EC, Cl-, SO42-, total hard
ness and alkalinity.
