High amounts of fluoride (>1.5 ppm) in drinking water is a serious issue in many parts of India. Fluorosis has been a serious issue in Andhra Pradesh, as early as 1999 with maximum reported levels at 29 ppm. Evidence indicates that 70-100% of the state is affected.

Chemistry of groundwater – A presentation by ACWADAM
Quality of water is quintessential. Quality of groundwater supply determines where and for what it can be used.

This presentation by ACWADAM deals with the chemistry of groundwater. It is now recognized that the quality of groundwater is as important as its quantity. All groundwater contains salts in solution which are derived from the location and the movement of water through rocks. The quality of groundwater supply depends where and for what it is planned to be used. Thus water quality standards for drinking water, industrial water and irrigation water differ significantly.
