Excess fluoride in groundwater-based drinking water supply is a growing concern in semi-arid tropical (SAT) regions of India. More than 16 states in India are facing the fluorosis problem. Several southern-peninsular states are experiencing monsoon climate condition, where the rainwater is harvested through tanks and used for agriculture.

High concentrations of fluoride (F–) in drinking water are harmful to human health. Knowledge of spatiotemporal distribution of F– content in groundwater is thus a prerequisite for taking preventive measures. This communication reports F– incidence in groundwater and its relation with the prevalence of fluorosis in Tamnar area, Raigarh District, Chhattisgarh, India.

This paper describes the results of a groundwater potentiality and quality assessment conducted in Koduvan Ar sub-watershed of Meenachil river basin, Kottayam district of Kerala state.

The groundwater crisis is acquiring alarming proportions in many parts of the country. Strategies to respond to groundwater overuse and deteriorating water quality must be based on a new approach involving typologising the resource problems and redefining the institutional structure governing groundwater. This approach is based on the notion of groundwater as common property.

Until the 1940s, the irrigation and drinking water needs of India were met by rivers, ponds, lakes, dugwells, and rainwater sources. However, in the middle of the 20th century India continually faced two daunting challenges: providing food for an ever-growing population and decreasing the burden of highly prevalent water-borne diseases, including cholera, dysentery, and typhoid.

Quantification of natural groundwater recharge is a basic prerequisite for efficient groundwater resource management and is particularly vital in an area where shallow groundwater is mostly polluted with highly toxic elements. It is especially critical where large and concentrated demand for groundwater supplies exist such as in urban areas, industrial zones and irrigated fields.

Chronic exposure of fluoridated groundwater causes a health problem not only to human beings, but also in domestic animals in the form of fluorosis.

Groundwater sampling was carried out at 25 locations from dug wells and bore wells in Rajpura tehsil in Chandrapur district during post monsoon season (October 2009) to assertion groundwater fluoride concentration.
