Fluoride is one of the most commonly found elements in the earth’s crust. It is naturally found d in water and helps in healthy tooth development and cavity prevention. However its high concentration in water can be harmful to human health. The amount of Fluoride (F) occurring naturally in groundwater is governed principally by climate, composition of the host rock, and hydrogeology. As per the World Health Organization and Indian Council of Medical Research the permissible limit to fluoride in drinking water is 1.5mg/L. Anything more than this value can cause fluorosis (dental and skeletal), which can affect the bones and teeth. In the backdrop of this aspect of water quality, this paper in RASĀYAN Journal of Chemistry,  tries to assess the exposure to fluoride through drinking water consumption and to elucidate fluoride endemic areas through mapping in Unnao district of Uttar Pradesh.

Wastewater irrigation in Hubli–Dharwad, Karnataka, enables farmers to diversify their cropping practices - A paper in the Environment and Urbanisation Journal
Farmers utilise the permanent streams of sewage-contaminated wastewater emanating from the twin city of Hubli–Dharwad to their advantage. This paper considers the effects of the availability of this perennial water resource and its effects upon livelihood practices of farmers and the implications for health.

A fundamental change in the principles, approach and strategies of water management in India has been proposed in the Twelfth Plan

Why is this paradigm shift needed ?
Ministry of Drinking Water and Sanitation and National Remote Sensing Centre release groundwater prospects maps for 14 states of India
Groundwater is our main source of water for domestic, agriculture and industrial use today and through base flows, it also maintains the flow in many of our rivers

It is therefore crucial that we look after this resource and ensure that it is managed properly.Over reliance on groundwater for both domestic and commercial purposes has led to over-exploitation and contamination of groundwater. In order to make groundwater sustainable, there is a need to understand the aquifer characteristics as well as its overall geological setting.
