quality is deteriorating in arid and semi-arid regions. Phulera
tehsil is facing the problem of groundwater
pollution. In the present investigation, determination of fluoride (F) in
drinking water was conducted in (200 samples of) 40 villages of Phulera tehsil having fluoride
content more than permissible limits (>1.5 mg l-1). After the
pilot survey symptoms of skeletal and gut fluorosis
have been found in almost every inhabitant. The water samples were alkaline
with pH ranging from 7.05 to 10.16. Electrical conductivity (EC) ranged from
157 ?mhoScm-1 to 1018 ?mhoS
cm-1. Calcium hardness (Ca-H) ranged from 10 to 127 mg l -1.
Total hardness (TH) varied from 69 to 572 mg l-1. Chloride varied
from 92.00 mg l-1 to 1422.00 mgl-1and
fluoride from 1.20 to 18 mg l-1. The alkalinity of
all water samples were found to be more than the permissible limit. The
results envisaged that the quality of ground water of? Phulera is
very poor, and is not suitable for drinking purpose and can only be used after
proper treatment. Key
