Rivers have been rendered to the level of sewage flowing drains. by Dr. Nitish Priyadarshi. email: nitish.priyadarshi@gmail.com Water is one of the most important commodities which Man has exploited than any other resource for sustenance of his life. Most of the water on this planet is stored in oceans and ice caps which is difficult to be recovered for our diverse needs. Most of our demand for water is fulfilled by rain water which gets deposited in surface and ground water resources. The quantity of this utilizable water is very much limited on the earth. Though, water is continuously purified by evaporation and precipitation, yet pollution of water has emerged as one of the most significant environmental problems of the recent times. Not only there is an increasing concern for rapidly deteriorating supply of water but the quantity of utilizable water is also fast diminishing. The causes of such a situation may be many, but gross pollution of water has its origin mainly in urbanizati...

Assessment of helium reservoir may be under taken in the Jharkhand state. By Dr. Nitish Priy adarshi. Fig: The above pictures are of Surajkund area in Hazaribag district in Jharkhand. Rocks of Jharkhand State in India which are mineral rich can also be used for trapping Helium deposit. In Jharkhand helium has been reported in the gases of different thermal springs of Hazaribag district. In Jharkhand, concentration of helium is highest in thermal gases of Surajkund (3.63 mole %) followed by Charhi (3.38 mole %), Duari (2.95 mole%), Barkagaon (0.29 mole %)and Badam (0.09 mole %). Surajkund hot spring (also called Surya Kund) is a natural hot spring in Belkapi gram panchayat of Barkatha community development block in Barhi subdivision of Hazaribag district in the Indian state of Jharkhand. Mineral radioactivity plays an important role in the natural occurrence of helium. Helium is an end product of radioactive decay. Helium is also known from the damp of many coal mines. The release of he...

Are the people of Ranchi suffering from SAD Syndrome? By. Dr. Nitish Priyadarshi Recent increase in suicidal incident in Ranchi city reminds me of an old research which says that it is not only the social issue which instigates people to commit suicide but also the climate change affects our mind and body. According to the research the changes in weather sharply affects our mind it may be peak winter season, summer season or rainy season. This theory is commonly known as SAD. SAD stands for Seasonal Affective Disorder. Ranchi city is famous for its sudden change in weather. SAD is a syndrome characterized by depression during winter months when there is less daylight. Seasonal Affective Disorder is directly related or even caused by too little sunlight, which causes the body's time clock to go out of sync, thus upsetting the body's routine, and may even affect certain hormonal levels in the body. The symptoms of SAD are depression, sadness, lethargy, fatigue, excessive sleeping...

The tremor left a 200-foot long/10-foot deep crater on the road. by Dr. Nitish Priyadarshi It is for the first time in earthquake history of Jharkhand that the earthquake, which jolted North and Eastern India on 19th September, left a 200-foot long crack on the NH-75 in Latehar district, disrupting traffic. The tremor left a 200-foot long/10-foot deep crater on the road disrupting traffic near Sikni Colliery. It came as surprise as the area is treated geologically as the most stable cratonic block related to tremors. According to the local administration it was due to Sikni coal mines near that highway. They said that the mining has created instability of the upper surface of the earth of near by areas and the cracks were the multiple effects of both mining and tremors. If it is true then most of the areas of the Jharkhand State where the coal mining are rampant are under tremendous threat in future. Geologically Jharkhand state represents a part of the Indian Peninsular shield, which ...

These methods are concerned with forecasting earthquake of a particular intensity over a specified locality within a specified time limit. by Dr. Nitish Priyadarshi Tectonic earthquakes are attributed to rupture in the rock masses which occur following accumulation of strain. Earthquakes present a frightening experience in the lives of men. The disaster strikes suddenly, similar to that of lightning, tornadoes or nuclear explosions. It is estimated that an average, about 15,000 human lives are lost every year, while in a singe year of 1976 about 200, 000 were killed by earthquakes in china, Guatemala, Philippines and in other parts of the world. The damage to property runs into billions of dollars. Earthquakes generate a variety of effects. Some are temporary, such as the shaking ground, swinging objects, rattling windows and oscillating trees. Permanent effects include damage to buildings, transportation, water supply systems and the landslides. Till today there is no perfect method t...

Most of the areas of New Delhi and its adjoining places are affected by salinity hazards. By Dr. Nitish Priyadarshi Inland salinity in ground water is prevalent mainly in the arid and semi arid regions of Rajasthan, Haryana, Punjab, Gujarat, Uttar Pradesh, Delhi, Andhra Pradesh, Maharashtra, Karnataka and Tamil Nadu. In some areas of Rajasthan and Gujarat, ground water salinity is so high that the well water is directly used for salt manufacturing by solar evaporation. Salts in groundwater originate either from minute quantities dissolved in rain water, from the chemical breakdown of rocks or from direct connection to sea water. Inland salinity is also caused due to practice of surface water irrigation without consideration of ground water status. The gradual rise of ground water levels with time has resulted in water logging and heavy evaporation in semi arid regions lead to salinity problem in command areas. Most of the areas of New Delhi and its adjoining places are affected by sali...

Groundwater is an important source of water supply throughout the world. by Dr. Nitish Priyadarshi The circulation of water: There is a continual movement of the earth’s water. The main reservoir is the ocean. From its surface water vapor is formed by the heat from the sun and carried up into the atmosphere by the air movement we called winds and breezes. The water vapor in the air is condensed to drops as the air rises and becomes visible as clouds. The contained moisture may then be precipitated as rain or snow or hail or mixture of these. The rain or snow which falls on the land may be partly re-evaporated, a part may flow into the streams and rivers and be returned to the ocean, and a part may sink into the ground where it supplies the moisture to the soil and also infiltrates downward into the rocks to form groundwater. Water occupying openings, cavities, and spaces in rocks is commonly known as groundwater. There are two main sources of such water : Juvenile water, which rises fr...
