The Nagaon Paper Mill, a public sector pulp and paper mill, a unit of Hindustan Paper Corporation Limited, is located at
Jagiroad, Morigaon district, Assam and generates about 448 tonnes
of lime sludge per day as solid waste. Instead of marketed lime,
Vikram Soni et al. explain a scheme for large-scale natural water storage in the Yamuna floodplains near Delhi. If the water is made to percolate in the aquifer by construction of several
barrages and tens of kilometres of bunds, then it cannot be called a
Ever since the Nobel Peace Prize was conferred on Al Gore and the UN Intergovernmental Panel on Climate Change (IPCC) in 2007, there has been widespread acceptance of the fact that we are in the midst of rapidly changing weather patterns. The connection between rising carbon dioxide (CO2) levels and global warming is
We present evidence that the Indian Sundarbans is experiencing the effects of climate change over the last three decades. Observations of selected variables, such as the surface water temperature, salinity, pH, dissolved oxygen, and transparency show significant long-term variation over a period of 27 years (1980
The Sariska Tiger Reserve, one of the important tiger habitats of Central India, came into limelight because of the disappearance of tigers from the area. It exemplifies another
Aquifer storage and recovery (ASR) is an effective method of recharging reclaimed or surplus surface water into confined or semi-confined permeable formations for later extraction. A key factor in the long-term viability of ASR is the extent of mineral interaction between two dissimilar water types, their recoverable fractions and consequent impact on water quality and aquifer stability.
The study was carried out to evaluate radioactive concentration
in food crops grown in naturally highbackground radiation areas in southwest India. Seventeen varieties of food crops were collected from different parts of Kanyakumari district. The gross alpha and beta activities of the collected samples were measured using alpha scintillation counter and low beta
counter respectively.
India has good average annual precipitation, but its poor distribution in space and time has led to the scarcity of groundwater in many areas. Artificial recharge to groundwater requires a composite procedure along with detailed morphometric and hydrogeological studies of the area. In Maharashtra State, a
