In our villages, water is sacred. It is the first thing we offer a guest and the last thing we deny even an enemy. Yet across Kalyana Karnataka, the water drawn from our borewells carries an invisible poison — fluoride — and it is quietly crippling a generation.

When fluoride in drinking water crosses the safe limit, it causes fluorosis: a slow, lifelong affliction. In its dental form, children's teeth turn yellow, brown and pitted. In its skeletal form, it stiffens the bones and joints of working men and women, bends the legs of the young, and leaves elders unable to stand straight or earn a living. There is no cure once the damage is done — there is only prevention.

The World Health Organization, and India's own drinking-water standard, fix the safe limit of fluoride at 1.5 mg per litre (National Health Mission, MoHFW). Beyond that line, every glass becomes a risk. And in our region, that line is crossed again and again.

A state-wide survey carried out between 2009 and 2014 — sponsored by the Union Ministry of Drinking Water and Sanitation and coordinated by the Karnataka State Remote Sensing Application Centre under the Rajiv Gandhi National Drinking Water Mission — tested 41,368 water samples. Of these, 4,039 sources were found with fluoride well above the permissible limit (Fluoride Action Network). That is roughly one in ten of the sources tested. The contamination is heaviest in the dry, hard-rock belt — the same districts that make up Kalyana Karnataka.

The numbers from our own soil are alarming. In Kalaburagi (Gulbarga), groundwater fluoride has been recorded as high as 7.4 mg per litre — nearly five times the safe limit. In Raichur, levels have touched 5.15 mg per litre. Across the state, Kolar reached 7 mg per litre and Tumakur 6.5 mg per litre. Yadgir, Gulbarga, Raichur, Koppal, Bidar and Ballari sit squarely among the twelve Karnataka districts worst hit by fluorosis (academic groundwater studies; Fluoride Action Network).

As if fluoride were not enough, the northeastern belt of Yadgir, Gulbarga and Raichur carries a second burden: arsenic in groundwater has been measured as high as 303 parts per billion in places, linked to gold-mining geology. Our people drink water that science calls hazardous on two counts at once.

This is where the question stops being merely medical and becomes one of justice. Why is it that the same districts long denied industry, irrigation and investment are also the districts left to drink poisoned water? The Government of India launched the National Programme for Prevention and Control of Fluorosis back in 2008–09. Two decades on, why do our borewells still run with 7 mg of fluoride per litre? Safe piped water, working defluoridation plants, regular testing and screening of every village child — these are not luxuries. They are the minimum a citizen of Kalyana Karnataka is owed.

The Kittur Kalyan Karnataka Sena stands for one principle: a child in Yadgir deserves the same clean glass of water as a child in Bengaluru. We demand a time-bound, district-by-district plan to bring every fluoride-affected village under safe surface-water supply; functioning, audited defluoridation units; and free, regular fluorosis screening in our schools and primary health centres.

Water is the most basic promise a government makes to its people. In our region, that promise has been broken for too long. It is time to demand it back — clear, safe, and ours.
