|Abstract:||Water occupies unique position in the universe. It is an essential component in five elements required for any living being. As all the metabolic reactions of every living organism are water based therefore, water is considered as ‘Life’. Water prevails an amphibious role viz. as carrier of diseases and as a medicine. World Health Organization report reveals that 80% diseases are waterborne. Likewise, ayurveda reveals that water is an elixir and acts as medicine. Due to increasing demographic pressure, urbanization and industrialization, the quality of our environment is being polluted and water quality is deteriorated. Increasing use of chemical fertilizers and insecticides have further aggravated the problem which inturn have contaminated all water resources, viz. ponds, wells, rivers and oceans. Ground water, being main source of water supply in India is becoming enriched with toxicities of nitrate, fluoride and arsenic, thereby converting an elixir of life to toxic liquid. In India 2.5 crore people are afflicted with the disease 'fluorosis' and are leading vegetative life. Major areas of West Bengal, Chattisgarh and Madhya Pradesh are prone to problem of arsenic toxicity in ground water whereas, major parts of Punjab, Haryana, Rajasthan, Madhya Pradesh, Delhi and Maharashtra are afflicted with the problem of nitrate toxicities in ground water. The physical, chemical and bacteriological properties of water are important in judging the suitability of water for potable purposes. Potable water should be devoid of any taste, colour and odour. The increased concentration of nitrate and fluoride in ground water have created socio-economic problem and have adversely affected the livelihood of inhabitants. Therefore, for sustainable development immense and immediate efforts are required to combat the problem. In the present communication the extent of problem, distribution of various hydrochemical parameters, their health effects and management measures will be discussed comprehensively.|
