Prescription for An Ailing River

Prescription for An Ailing River

Rivers are an essential part of our lives and the ecology. But we turn them into drains. Here is how we can help save our rivers.

Colourful Waters—Wow or Worry?

Colourful Waters—Wow or Worry?

Water is colourless. But when we observe any large water body, it appears blue. When it has a lot of impurities (or nutrients), it can vary from red, green, white, grey, brown, black to anything that is weird and filthy. Read about some important terms related to different colours of water that we come across in common parlance or which researchers use to understand better this elixir of life. Bluewater: ‘Why is water blue in colour?’—humans must have raised this question since time immemorial. But in 1921, this query was resolved when Sir CV Raman raised and answered it successfully...

It’s Not Any Snow

It’s Not Any Snow

A refreshingly sweet and innocent observation by a child of an otherwise very worrying issue of—river pollution—with a heartwarming appeal for water conservation. Once upon a time, during the holidays, I was travelling from Delhi to my village nearby. On the way, we guys came across the Yamuna River. Looking at the river, my younger brother instantly commented, “It doesn’t snow in Delhi even during winters. But here, on the river, it seems to have snowed in peak summers!”... Then, I explained to him that the white foam on the river surface is not snow but the chemical effluents emitted by huge …

Jab We Met: The Han Meets the Yamuna River…

Jab We Met: The Han Meets the Yamuna River…

The Han meets the Yamuna river and tells her how even she can flow and flourish in peace. Han smiled and hugged Yamuna. For a moment, Yamuna forgot the toxic filled surrounding she lived in. Yamuna lowered her eyes and began opening up to Han. “Look where I live Han. I cannot breathe; move my arms or even my feet. Every day, the drains add more filth into the river and the people of the city for whom I travel from so far, do not even throw a glance at me. For them, I am a stinky black drain.”

Only Eco-friendly Cleaners

Only Eco-friendly Cleaners

Performing tangible actions to achieve credible solutions—making eco-friendly cleaning agents and raising awareness on chemically-intense products to control pollution. ******************************************************************************** The unsettling sight of the Bellandur Lake—a foamy, cloudy demon gargling bubbles—and plastic litter—baffling mounds disposed irresponsibly—motivated me to act and revive our wonderful world. We all know that the climate crisis is going off the charts and the practise of ‘Reduce, Reuse, and Recycle’ is gaining alarming urgency. Thus, it&…

The Mega Problem of Micro Things

The Mega Problem of Micro Things

What are Micro-Plastics? Micro-plastics have not been defined in particular. They are just tiny particles that result from the disintegration of bigger plastic materials. However, most researchers say that any plastic smaller than 5 millimetres in size is a micro-plastic. Hence, these are really, really teeny-tiny! Plastics are made up of polymers, which are derived from fossil fuels. A whole lot of chemicals are added to the polymers—close to 10,000—to ensure that a given plastic has the desired properties...

Yamuna Travails

Yamuna Travails

The Yamuna River is the largest tributary of the Ganga. It travels barely a distance of 22 km through Delhi. However, this region contributes to about 80 per cent of its total pollution load. Currently, this stretch discharges waste water from almost 22 drains into the river. Untreated effluents, containing toxins and chemicals, released from houses and industries creates froth (white foam) on the river’s surface. Algae, in addition, prevents sunlight from venturing into the depths of this river. Plus, low water level in the river causes concentration of these pollutants…

Burst Water Bubble
To Burst or Not to Burst?

To Burst or Not to Burst?

To burst or not to burst?’ is a question many young humans might be asking as the patakha (firecracker) season begins. Teachers and doctors tend to advice against firecrackers but there’s always a paan-chewing uncle or a macho friend who’ll bully you kids into becoming enthusiastic arsonists. It’s usually a tough choice to make. Some additional information is always a good help in firming up ones’ resolutions. Therefore, let's throw some light on the history, chemistry, and eco-friendliness of patakhas.

How a Group of Citizens Revived a British-era Lake in Salem

How a Group of Citizens Revived a British-era Lake in Salem

Salem is one of the largest cities in Tamil Nadu, India. More than 1 million people live here. Piyush Manush is the convener of the Salem Citizen's Forum (SCF). SCF is an informal group, involved in protecting Salem's environment. The lake was built by the British for irrigating nearby farmlands. The lake is spread across 58 acres and used to be a major water body of the city. But gradually it became a dumpsite for Salem's municipal solid waste. In 2010 SCF took over the work of cleaning the lake. But first, they had to get rid of the garbage and then desilt the waterbody.

Reviving a Lake using Artificial Wetlands in Delhi

Reviving a Lake using Artificial Wetlands in Delhi

Wetlands purify water through natural processes where aquatic plants act as bio-filters. Plants absorb phosphates and nitrates from the water and roots help to put back oxygen into the water. Constructed wetlands are a cost-effective method of treating wastewater and polluted water bodies. These are low cost solutions and can be easily made or replicated.
