there are increasing number of fluorosis cases among the residents of Delhi. Fluorosis is caused by consuming water contaminated with fluoride.
A recent survey to check the content of fluoride in the water in the four zones of the National Capital Territory of Delhi ( nctd ) revealed that the highest contamination is in the North West and Western zones. The second highest fluoride contamination of water was found in the North East and Eastern zones.

According to A K Susheela, a physician with the non-government organisation ( ngo ) Fluorosis Research and Rural Development Foundation, the Jal Board is unable to supply the requisite demand for water in the city. "To make up for the shortage, residents dig tube-wells and hand pumps to tap the groundwater which is believed to be safe and is therefore never tested for its quality," she said. People consuming this water are exposed to the risk of fluorosis.
