World Environment Day: India’s water crisis is dirty, damaging.
1/8 Contaminated with sewage and other industrial waste, more than half of India’s rivers are polluted and pose a threat to quality of water and aquatic life .
Being the second most populous nation in the world, roughly half of the country’s population still practices open defecation and eighty percent of sewage flows untreated directly into the rivers, polluting the main sources of drinking water.
With high levels of contamination in the water bodies, many cities in India are likely to face a serious shortage of clean water in the years to come.
With World Environment day being celebrated across the globe, highlighting and creating awareness regarding environmental issues is a must on a global level.

WASHINGTON, May 3, 2017—Center for Food Safety (CFS) today released Water Hazards 2.0: Continued Aquatic Contamination by Neonicotinoid Insecticides in the United States, an update to the 2015 report, “Water Hazard: Aquatic Contamination by Neonicotinoid Insecticides in the United States,” which shows continued widespread water contamination from neonicotinoid insecticides.
In particular, the report draws attention to new research that shows a presence of these pesticides in water bodies across the country at levels known to be toxic to several aquatic invertebrates.
Neonicotiniod seed coatings, the largest use of these chemicals, are still not regulated by the Environmental Protection Agency (EPA).
As this report update makes clear, the scientific evidence continues to mount, yet so far, the EPA has taken no mitigation measures to deal with this growing crisis in our environment,” said Larissa Walker, pollinator program director at Center for Food Safety.
This is concerning as representative studies highlighted in this year’s follow-up report show that continued exposure to neonicotinoid chemicals may cause irreparable neural damage to species impacted, leading to rippling negative effects throughout the food web.
In light of new science and EPA’s inaction in the face of continued contamination, the report makes numerous additional policy recommendations to EPA to stem this ongoing crisis, especially in relation to shortcomings in the agency’s Preliminary Aquatic Risk Assessment to Support the Registration Review of Imidacloprid: EPA in the final risk assessment should more accurately portray the risk posed by seed-coatings.
Background: Neonicotinoid products are applied on more than 150 million acres of crop land annually, with seed coatings being the most common form of application.
Peer-reviewed studies from Holland already show that neonicotinoid contamination correlates significantly with bird population declines and numerous other species are thought be at risk.
There is also new science suggesting that sub-lethal exposure in agricultural landscapes is damaging to wild bees and could have long term repercussions on populations.
Other recent studies – including by EPA itself – have reinforced CFS’s report.

DNA Analysis Of Diatom Algae Would Help Researchers To Track Down The Level Of Water Pollution.
Scientists are now planning to use them as bioindicators to monitor water parameter.
To get out from this issue, a team of biologists from University of Geneva (UNIGE), Switzerland have established a water quality index based on the DNA sequences of Diatoms.
In the journal of Molecular Ecology Resources researchers explained, the index presents a revolutionary tool that allows scientists to process a large number of samples without identifying each species visually.
Human activities are resulting water pollution in the river, and the degree of pollution is reflecting the ecological status of a river.
Several organisms have different ecological preferences and pollution tolerance that can be used as the bioindicators.
However, no longer meets the needs of rapid and reliable bioassessment measures introduced to protect aquatic environments”.
his team has prepared a Swiss diatom index (DI-CH) to determine the ecological status of rivers.
As per the report by Phys, researchers have collected more than 90 samples from the different rivers of Switzerland and analyzed the ecological status by using DI-CH.
With the collaboration of Geneva Water Ecology Service (SECOE) and the PhycoEco, environmental office researchers created a molecular index from the DNA sequences characteristic of all the diatom species.

Water pollution is a serious problem for all the people & living species on earth.
Water is get polluted when the different harmful heavy metals like mercury, lead, cadmium etc.
& chemicals from industrial or sewage wastes which are put directly in the rivers or oceans dissolves the gases like methane, carbon dioxide etc.
in water which would decrease the BOD i.e. biological oxygen demand of different micro-organisms & aquatic fauna leading to their death due to less availability of oxygen for them for survival.
The different examples of water pollution are; dumping of sewage & industrial wastes in the fresh water of rivers or lakes or in oceans, washing of clothes in rivers & canals, contamination or water bodies by addition of nuclear or radioactive wastes etc.
The different types of water pollution are: Ground water pollution Underground water pollution Surface water pollution Microbial water pollution Chemical water pollution Nutrient water pollution The different causes of water pollution are: Dumping of industrial & sewage wastes into water bodies without treatment.
The direct dumping of untreated sewage wastes from the cities into the rivers or oceans will lead towards the pollution of these natural resources of water & depletes the aquatic ecosystems of these places.
Dumping of animal wastes in the water resources is also a main cause of water pollution.
This problem is created by the different processes such as oil splitting from ships or pipelines, adding of sewage & industrial wastes directly to the water units, acid rain, addition of cattle dung or wastes to the water resources of earth, deforestation or burning of forests, acidification of oceans etc.
Acidification of oceans & rivers: The addition of pollutant like carbon dioxide into water more than permissible limits would responsible for the acidification of ocean water which will result in depletion of oceanic ecosystems due to less availability of oxygen for survival to inhabitants of that aquatic ecosystem.
