India is extremely rich in water resources. The country is endowed with large network of great rivers and vast alluvial basins to hold ground water. By virtue of its peculiar placement in the foothills of the magnify Himalayas and having the ranges of Sathpoora, Aravali and the decade plateau running through it the country has huge water resources which have been meagerly tapped. Over water resources can be divided into two broad categories viz., the surface water resources and the ground water resources. Each of these is a part of the earth’s water circulatory; system called the hydrologic scale and each is ultimately derived from precipitation i.e., rainfall and snow. A part of the annual rainfall is held up in the undulating land surface and seeps down beneath it to give subsoil water resources. The amount which thus does not seep down flows in the form of streams and unions, the river system, another part which evaporates, forms moisture in the atmosphere which may another clouds, rain and snow. Thus all forms of water resources are inter dependent as the loss of one may be the gain of the other.

On new moon day when Moon passes between Earth and Sun solar eclipse can be seen from Earth. Although solar eclipse is a fascinating astronomical event, even in today’s fast, modern and civilized life, people have not been able to go away with superstitious beliefs related to outer space activity behind solar eclipse. These misbelieves eventually lead to great socio-economic losses due to discarding of cooked food and drinking water that was exposed to the eclipse directly or indirectly. So considering these misbelieves a study was conducted to see possible biological effects of solar radiations during solar eclipse on bacteria responsible for water borne and food borne diseases. E. coli, S. aureus, B. subtilis, S. typhi, which are known water and food borne pathogens, were exposed to solar radiations throughout the eclipse period. The effect of these radiations on the survival and growth rate of these organisms was assessed by suitable method and compared with that on control day. When such comparison was made, it indicated that there was no statistically significant effect of solar eclipse on the survival and the growth rate of these organisms. Hence, we insist dumping the cooked food or drinking water after solar eclipse should be avoided.
