Water pollution

A disease in Dhanbad has left children without smiles

High fluoride content in groundwater is crippling entire generations in several Dhanbad villages, leaving them with weak bones and stained teeth.

Sixty-eight-year-old Himanshu Chakrabarty of Brahman Tola village in Ghadbad panchayat of Dhanbad has only one desire – death. For more than 15 years, he has suffered from weak and deformed bones with almost no flesh on his body, limping around like a living skeleton. A patient of a crippling disease called fluorosis, which caused due to an excess intake of fluoride, Chakrabarty wants an end to his suffering. “I only want death,” he cries out in pain. “How much more do I have to suffer?”

Chakrabarty isn’t the only one suffering in Brahman Tola. “Each of the 68 households in our hamlet has at least one patient suffering from fluorosis,” resident Rajit Thakur told VillageSquare.in. “Almost 60% men and over 75% women of the tola are affected by the disease in some form or the other.”

Fifty-year-old Savitri Mukherjee, a widow, lives alone and cannot walk with her spine straight. “It started with pain in my shoulders, back and knees. But, for the last five years, I am walking with a bent back,” said Savitri. “If I fall on the ground, I cannot get up on my own. I cannot sleep straight on the bed. It’s been five years since I have seen the sky (with back always bent downwards). There are several women like me.”

The common thread tying all the residents of Brahman Tola with a single disease – fluorosis – is their drinking water. “The groundwater of Brahman Tola and its neighboring villages in Ghadbad and Birsinghpur panchayats of Baliapur block is laced with high fluoride. Groundwater is the primary source of drinking water for these villages, which depend on hand pump and dug well to meet their daily water needs,” Eklavya Prasad, managing trustee of Megh Pyne Abhiyan or MPA, a non-profit working on water and sanitation issues, told VillageSquare.in.

High fluoride in groundwater

Chakrabarty used to live in the Purulia district of West Bengal and moved to Brahman Tola in Dhanbad district of Jharkhand about 38 years ago. “Till about 20 years ago, we used to drink water from a dug well near the village school. Then hand pumps were sunk,” reminisced Bani, wife of Chakrabarty. “We were told that hand pump water was clean and pure, but within five years my husband started to complain of pain in the bones and joints.”

“The pain started from my right leg and slowly moved upward in my back. Then, my entire body was affected. Getting up from the bed and moving around has become a challenge,” said Chakrabarty, who has consulted doctors at Dhanbad and Asansol in West Bengal, all of whom have diagnosed him with fluorosis and prescribed painkillers. “Doctors claim that I got this disease from drinking water. So, I have only two choices – die without water, or die drinking poisonous water,” said an exasperated Chakrabarty.

“Fluorosis is a painful and crippling disease,” said Manish Kumar, a radiologist in Dhanbad who often receives fluorosis patients. “High fluoride in the body starts depositing on the bones and as fluoride deposition increases in bones, calcium starts to decrease, making bones brittle.” This is not all. Bones and muscles are joined together through tendon. “Even tendon starts having calcification. Fluoride also deposits on intervertebral disc (which serves as the spine’s shock absorber), because of which patients experience severe back pain and cannot walk straight.”

How much is too much?

Fluoride is a micronutrient and is widely distributed in the earth’s crust, mainly as the minerals fluorspar, fluorapatite and cryolite. According to the World Health Organization, fluoride intake has both beneficial effects in reducing the incidence of dental caries, and negative effects in causing tooth enamel and skeletal fluorosis following prolonged exposure to high concentrations.

The dental effects of fluorosis develop much earlier than the skeletal effects in people exposed to large amounts of fluoride, says WHO. Clinical dental fluorosis is characterized by staining and pitting of the teeth. In more severe cases, all the enamel may be damaged.

The WHO has set the fluoride guideline value of 1.5 milligram per liter for drinking water, beyond which fluoride starts to show adverse human health effects. In India, the BIS drinking water standard for fluoride is divided into two parts – an acceptable limit of 1 mg/l, and a permissible limit of 1.5 mg/l in an absence of an alternate source.

But, the groundwater and drinking water supply in several regions of the country contains high fluoride levels. The Union Ministry of Health and Family Welfare has recently identified at least 132 districts in 19 states severely affected by high fluoride content in drinking water, a leading cause of fluorosis.

“The terms like acceptable and permissible limits do not make sense. It should be toxicity limit and down to 0.5 mg/l because, even at that level, fluoride can affect human health,” Sunderrajan Krishnan, director of Anand-based INREM Foundation, a research institution working on water, public health and agriculture, told VillageSquare.in. Krishnan has done extensive field-based research on impacts of fluoride on human health.

Test result: Fail

According to the residents of Brahman Tola, a couple of years ago, the Public Health Engineering Department or PHED tested water quality of hand pumps in their village.

“The PHED officials painted some hand pumps red and told us not to drink water from them, as they contained high levels of fluoride. But, the government has not provided any alternate source of water. Hence, we drink contaminated water knowingly,” lamented Ashish Sarkhel, another resident suffering from skeletal fluorosis. “Initially, I had only back pain, but in the last seven years, my condition has worsened. I used to work in a factory, but had to give up my job.”

Last December, MPA carried out a survey of high-fluoride affected villages in Ghadbad, Birsinghpur and Machiyara panchayats of Baliapur administrative block in Dhanbad district. Water sources of Brahman Tola were tested as well. Children were screened for dental fluorosis at local schools.

“Using field-kits, we tested water quality of 11 villages and hamlets in the three panchayats. A total of 45 dug well samples and 78 hand pump samples were tested. Of these, only six samples of dug wells and three samples of hand pumps were found safe for drinking. The rest had fluoride levels above the permissible limit,” said Pradeep Poddar, program officer at MPA.

Entire generation affected

The situation is so grim in Brahman Tola that its children refuse to smile. They fear their smile will expose their stained teeth (dental fluorosis) to visitors. “More than 90% of the children in the tola have stained teeth. No child above the age of six or seven years has clean white teeth,” said Thakur. “Our entire younger generation has been blotted.”

“I used to have clean, white teeth. But, for the last three-four years, my teeth have developed brown stains. Elders tell me that it is due to the water I drink. My friends also have stained teeth,” said Debu Sarkhel, a nine-year-old who studies in the 6th standard of the local middle school.

All the children in the middle school – Utkramit Madhya Vidyalaya, Ghadbad – which is till the 8th standard, drink water supplied from a 400-feet deep tube well within the school premises. “Earlier, the school hand pump was only 150 ft deep. Last year, as part of a drinking water scheme for the school, the hand pump was dug deeper to 400 ft,” Thakur said. “We fear that even at 400 ft depth, fluoride is present in the groundwater.”

Private gains

While fluorosis has become a public health issue in the affected villages, private companies selling bottled water are making private gains. Almost daily, vans supplying bottled water visit the affected villages.

“I cannot bear to see my husband suffer every minute. So, I buy 20-liter bottled water for Rs 20. Both my husband and my son drink that water. I continue to drink the hand pump water,” said Bani, wife of Chakrabarty.

The condition of 60-year-old Gita Chatterjee, a widow, is worse. She lives alone and can barely walk a few steps. “I have to beg and request village youth to fetch me some drinking water,” said a hapless Gita. According to Thakur, only 10-12 families in Brahman Tola have the money to buy 20-litre jar of drinking water. “Fluorosis has crippled us and we cannot earn a living. Buying bottled water is an additional cost,” he lamented.

Drinking water scheme in limbo

The state government and the district administration are aware of the sufferings of people in the fluoride-affected panchayats. Three years ago, Rs 7 million worth of drinking water treatment and supply scheme for the affected villages, including Brahman Tola, received technical sanction from the state government.

As per the scheme, water of Damodar River is to be treated and supplied to the villages through piped water supply. Villagers have to pay a user fee to the village water sanitation committee. But, the scheme hasn’t made much progress.

“The work is already underway. It was expected to be completed by November, but there has been some delay. The scheme should be functional by March next year,” said Kuldeep Chaudhary, deputy development commissioner of Dhanbad.

According to him, the Dhanbad Mineral Fund Trust, which is based on royalty received from mining companies in the district, is highest in the country, somewhere between Rs 50-60 million. “Sanitation, water and environment are the priority areas where we want to spend the trust fund. We can use money from this fund to support the villagers suffering from fluorosis,” added Chaudhary.

The people of Brahman Tola and the surrounding villages have suffered enough in the past few decades. An entire young generation is at the risk of being crippled for life. The government must act on a war footing and supply safe drinking water to the people.

Relying on the power of habits to solve India’s mammoth sanitation problem

Adopting three simple habits can help maximise the benefits of existing sanitation infrastructure.

India’s sanitation problem is well documented – the country was recently declared as having the highest number of people living without basic sanitation facilities. Sanitation encompasses all conditions relating to public health - especially sewage disposal and access to clean drinking water. Due to associated losses in productivity caused by sickness, increased healthcare costs and increased mortality, India recorded a loss of 5.2% of its GDP to poor sanitation in 2015. As tremendous as the economic losses are, the on-ground, human consequences of poor sanitation are grim - about one in 10 deaths, according to the World Bank.

Poor sanitation contributes to about 10% of the world’s disease burden and is linked to even those diseases that may not present any correlation at first. For example, while lack of nutrition is a direct cause of anaemia, poor sanitation can contribute to the problem by causing intestinal diseases which prevent people from absorbing nutrition from their food. In fact, a study found a correlation between improved sanitation and reduced prevalence of anaemia in 14 Indian states. Diarrhoeal diseases, the most well-known consequence of poor sanitation, are the third largest cause of child mortality in India. They are also linked to undernutrition and stunting in children - 38% of Indian children exhibit stunted growth. Improved sanitation can also help reduce prevalence of neglected tropical diseases (NTDs). Though not a cause of high mortality rate, NTDs impair physical and cognitive development, contribute to mother and child illness and death and affect overall productivity. NTDs caused by parasitic worms - such as hookworms, whipworms etc. - infect millions every year and spread through open defecation. Improving toilet access and access to clean drinking water can significantly boost disease control programmes for diarrhoea, NTDs and other correlated conditions.

Unfortunately, with about 732 million people who have no access to toilets, India currently accounts for more than half of the world population that defecates in the open. India also accounts for the largest rural population living without access to clean water. Only 16% of India’s rural population is currently served by piped water.

However, there is cause for optimism. In the three years of Swachh Bharat Abhiyan, the country’s sanitation coverage has risen from 39% to 65% and eight states and Union Territories have been declared open defecation free. But lasting change cannot be ensured by the proliferation of sanitation infrastructure alone. Ensuring the usage of toilets is as important as building them, more so due to the cultural preference for open defecation in rural India.

According to the World Bank, hygiene promotion is essential to realise the potential of infrastructure investments in sanitation. Behavioural intervention is most successful when it targets few behaviours with the most potential for impact. An area of public health where behavioural training has made an impact is WASH - water, sanitation and hygiene - a key issue of UN Sustainable Development Goal 6. Compliance to WASH practices has the potential to reduce illness and death, poverty and improve overall socio-economic development. The UN has even marked observance days for each - World Water Day for water (22 March), World Toilet Day for sanitation (19 November) and Global Handwashing Day for hygiene (15 October).

At its simplest, the benefits of WASH can be availed through three simple habits that safeguard against disease - washing hands before eating, drinking clean water and using a clean toilet. Handwashing and use of toilets are some of the most important behavioural interventions that keep diarrhoeal diseases from spreading, while clean drinking water is essential to prevent water-borne diseases and adverse health effects of toxic contaminants. In India, Hindustan Unilever Limited launched the Swachh Aadat Swachh Bharat initiative, a WASH behaviour change programme, to complement the Swachh Bharat Abhiyan. Through its on-ground behaviour change model, SASB seeks to promote the three basic WASH habits to create long-lasting personal hygiene compliance among the populations it serves.

This touching film made as a part of SASB’s awareness campaign shows how lack of knowledge of basic hygiene practices means children miss out on developmental milestones due to preventable diseases.


SASB created the Swachhata curriculum, a textbook to encourage adoption of personal hygiene among school going children. It makes use of conceptual learning to teach primary school students about cleanliness, germs and clean habits in an engaging manner. Swachh Basti is an extensive urban outreach programme for sensitising urban slum residents about WASH habits through demos, skits and etc. in partnership with key local stakeholders such as doctors, anganwadi workers and support groups. In Ghatkopar, Mumbai, HUL built the first-of-its-kind Suvidha Centre - an urban water, hygiene and sanitation community centre. It provides toilets, handwashing and shower facilities, safe drinking water and state-of-the-art laundry operations at an affordable cost to about 1,500 residents of the area.

HUL’s factory workers also act as Swachhata Doots, or messengers of change who teach the three habits of WASH in their own villages. This mobile-led rural behaviour change communication model also provides a volunteering opportunity to those who are busy but wish to make a difference. A toolkit especially designed for this purpose helps volunteers approach, explain and teach people in their immediate vicinity - their drivers, cooks, domestic helps etc. - about the three simple habits for better hygiene. This helps cast the net of awareness wider as regular interaction is conducive to habit formation. To learn more about their volunteering programme, click here.
