Mercury and Methylmercury: detect and discriminate
(0)Mercury in the environment is dangerous to human health. Methyl mercury is even more so. Nilanjan Dey from BITS Pilani, Hyderabad has designed a cost effective and highly sensitive method to detect both.
Wastewater Reuse: Decentralising treatment plants
Centralised water treatment plants in urban areas have high cost of maintenance. Researchers from IIT Madras have now come up with a solution: an optimised network of grey water and wastewater treatment plants. A must read for municipal authorities.

Groundwater Quality Assessment: Udhampur District
As Udhampur district is becoming more urbanised, the groundwater resources may become unsustainable and contaminated. Researchers from the University of Kashmir draw a baseline for monitoring groundwater quality.

Groundwater Recharge Zones: Machines learn to predict
Which are the best areas to construct groundwater recharge structures to overcome the outcome of overexploitation of groundwater resources? How can we leverage on machine learning to make sense of the abundance of data on the factors that determine groundwater recharge? And map the recharge potential? N Sadhasivam from the Bharathidasan University explores.

Duckweed in Action: Checking xenobiotic pollution
Duckweed may be called a weed, but we may need to change our attitude to it. It may be useful to clean up aquatic ecosystems, says a research team from Doon University. The weed, of course, suffers from Ofloxacin antibiotic in water, but removes it efficiently.

Hotspots for Stormwater Harvesting in Dehradun
Researchers from IIT Rourkee identifies the ideal sites for stormwater harvesting in Dehradun district using a web based geographic infomation system that allows public participation in decision making.
Growing nitrogen-doped graphene quantum dots on carbon fabric
Nitrogen-doped graphene quantum dots have incredible photocatalytic and electrocatalytic properties. Scientists have now found a way to grow them on carbon fibre, for use in cleaning polluted water.

Groundwater in the Deccan Traps: Estimating protective capacity of aquifers
Satara, Solapur and Sangli are in the dry Deccan volcanic province. While locating groundwater in the region, researchers from the Indian Institute of Geomagnetism point out that there is urgent need to protect the aquifers from contamination.

Past Hydrology of the Chautang Channel: dating geomorphological events
Archaeologists have come to a consensus that many societies from the Harappan civilisation seemingly thrived along the palaeochannels of the present Ghaggar and Chautang rivers that once existed east of the Indus. Though there have been claims of associations between these palaeo-river systems and the scriptural rivers, the Saraswati and the Drishadvati, there hasn’t been… Read More ›

Cooking with Arsenic: a gruelling story
While public discourse focus attention on arsenic in ground water, researchers from West Bengal call attention to arsenic in cooked rice.
