Fluorosis is the public health problem written into India's groundwater: fluoride that comes out of the rock itself rather than from any industry, and that damages teeth and bones over years of drinking. The National Programme for Prevention and Control of Fluorosis is the answer to it, and a Health Ministry workshop in September 2026 asked how to widen its reach. The remedy is safe water, not treatment.
UPSC has asked
- Prelims 2013: pollutants in drinking water in India, including fluoride
Where the fluoride comes from
- India's groundwater fluoride is largely geogenic, so the fix is safe water and defluoridation, the removal of fluoride from what people drink.
- IS 10500, the Bureau of Indian Standards drinking water standard, sets 1.0 mg per litre as the acceptable fluoride limit, relaxed to 1.5 where no other source exists.
- The National Environmental Engineering Research Institute (NEERI) developed the Nalgonda technique, a low cost community defluoridation method.
The two forms
Dental fluorosis
- Mottles and pits tooth enamel
Skeletal fluorosis
- Builds up in bone over years
- Bones turn dense and brittle, joints stiff
What has happened
