Shimla: An advisory has been issued by the Shimla Municipal Corporation to boil drinking water as a precaution as samples of several sources including tanks and tube wells have been found contaminated with Citrobacter, Klebsiella oxytoca and Pseudomonas ssp bacteria.
These bacterias are associated with serious health problems including physical diseases to infections in various parts of the body.
As per the latest report released by the Indira Gandhi Medical College, Citrobacter bacteria was found in the samples taken from the public tap on Sanjauli Chowk and in Tibetan colony in Nabah and water tank in Phagli.
The samples taken from the water tank in Sector 3 of New Shimla were contaminated with Klebsiella oxytoca bacteria.
Despite spending on the installation of Ultra Violet water treatment technology, the samples of the Ashwani Khud keep failing the quality tests. The treated and untreated samples taken from Ashwani Khud contained Pseudomonas spp and Citrobacter, thus, failed the test.

As a matter of serious concern, a video of showing the gigantic amount of plastic/solid waste and sewerage floating in the Khud that had gone viral on social media shows that the degradation of this source had only increased.
Further, samples taken from a hand pump in Chalaunthi and Engine Ghar were also found contaminated.
The Chau\launthi bawari and Bir Khana bawari in Kanlog also failed the test.
The samples were collected between 14 to 17 July.
The SMC, on the other hand, suggested that there could be some error in collecting samples and the water would be tested again.
The promises of the current SMC to provide clean and regular drinking water supply have fallen flat on their face. The Corporation is spending on water treatment technologies blindly without going into details of the causes that are leading to water contamination.
Former Mayor of Shimla and leader of Communist Party of India (Marxist), Sanjay Chauhan, condemned the act of putting public health at risk by supplying contaminated water to the citizens. He also questioned spending on expensive Ultra Violet Technology to treat water of Ashwani Khud as the samples of the same are still failing.
We can see in the reports also that samples of UV treated water have failed,
Sanjay pointed out
Malyana STP is almost redundant and about 4.5 MLD raw and untreated sewer water is released in the Ashwini Khud from this STP. It can’t be even treated with UV treatment,
he said when asked why spending on UV technology was in vain.
Moreover, it can’t be foolproof because of our lousy handling of plants and pumping stations. Nowhere in the world sewer treated water used for drinking. It’s used for agricultural and other purposes,
The SMC is still rationing water supply. While most of the localities are supplied water after a gap of one day, some localities complained they were still receiving even rationed supply regularly, he said.
Currently, the city requires 30 MLD water per day to meet the total demand and MC is receiving 40-45 MLD water per day, but still the public is not receiving regular water supply, Sanjay said.
The water pumps at the supply schemes are shut down for several hours as storage tanks of the Corporation remain full, which could be easily avoided if the town is given daily supply.
Further, Sanjay also pointed out that the SMC has decided to cancel the Greater Shimla Water Supply & Sewerage Circle (GSWSSC) and to hand over the water supply in the municipal area to a newly formed private company. However, no attention was paid on improving the quality of the water, he said.
The MC should learn from the way the privatization of sanitation works is already heading towards a failure even before it could be implemented in the entire town.
The CPI(M) has demanded supply of clean water supply to the town and the revival of the GSWSSC instead of handing the supply to private hands, which, it expects, would only worsen the situation.
Otherwise, the party warned the government of public protests.
The Ward Councilors and the Deputy Mayor recently visited Kerala as a study tour, if the SMC to be believed. The MC claimed it studied the methodology of the civic bodies of the State to learn how to supply 24×7 water. It further claimed, it would implement the same in Shimla town and by October, some of the Wards would start to get non-stop supply.
In reality, that credit would go to the ongoing Kol Dam project that has faced a delay of over five years before it was taken up following the severe scarcity of drinking water in the town.
Currently, the civic body needs to focus on the issue of contamination of drinking water supply. The public money must be spent judiciously while buying more technologies for the treatment of water. The government departments need to take up the task of conducting research studies/surveys to comprehend the real problem and buy a suitable technology or take steps accordingly.
Diseases Caused by Citrobacter Bacteria
The members of this species can cause several infections and diseases primarily in neonates and individuals with a weak immune system. It can cause nosocomial infections of the respiratory tract, urinary tract, and the blood. Further, Citrobacter is the well-identified cause of sporadic pneumonia, Hepatic, biliary and pancreatic disease, and neonatal sepsis and meningitis.
The mortality rate of Citrobacter meningitis is unacceptably high, with death rates of patients ranging from 25 to 50 %. About 75 percent of the survivors face serious neurological problems.
Diseases/infections caused by Klebsiella oxytoca
Klebsiella also targets individual with a weak immune system including diabetic patients, alcoholics, those using catheter tube, antibiotics for long time and ventilators.
Klebsiella normally lives inside the human intestine but it does not cause any disease in the intestine. Klebsiella causes a range of illness to the human body including, pneumonia, wound infection, surgical site infection, bloodstream infection, urinary tract infection and meningitis.
Diseases/infections caused by Pseudomonas ssp bacteria
As opportunistic pathogens, Pseudomonas spp. often invades the host tissue and cause infection and bacteremia in immunocompromised hosts (e.g., HIV/AIDS, cystic fibrosis, bronchiectasis, and severe chronic obstructive pulmonary disease, burns, malignancy, or diabetes mellitus)
The common site of infection is the lower respiratory tract, and severity ranges from colonization without immunological response to severe necrotizing bronchopneumonia.
It’s also a common cause of nosocomial ventilator-related pneumonia. Infections also include endocarditis, osteomyelitis, urinary tract infections, gastrointestinal infections, meningitis, and, commonly, septicaemia.
The symptoms depend on the location of the infection in all three cases. However, some of the common symptoms include fever, flu symptoms, breathing issues and cough.
Freshwater Pollutants To Become Major Cause of Deaths by 2050, warns UN Study
The most comprehensive and rigorous assessment on the state of the environment completed by the UN in the last five years was published today. The report, which was produced by 250 scientists and experts from more than 70 countries, says that either we drastically scale up environmental protections, or cities and regions in Asia, the Middle East and Africa could see millions of premature deaths by mid-century.
Pollutants in our freshwater systems will see anti-microbial resistance become a major cause of death by 2050 and endocrine disruptors impact male and female fertility, as well as child neurodevelopment”
the study warned.
The science is clear. The health and prosperity of humanity are directly tied to the state of our environment. This report is an outlook for humanity. We are at a crossroads. Do we continue on our current path, which will lead to a bleak future for humankind, or do we pivot to a more sustainable development pathway? That is the choice our political leaders must make, now,
said Joyce Msuya, Acting Executive Director of UN Environment.
Innovative Policy Options
The projection of a future healthy planet with healthy people is based on a new way of thinking where the ‘grow now, clean up after’ model is changed to a near-zero-waste economy by 2050. According to the Outlook, green investment of 2 per cent of countries’ GDP would deliver long-term growth as high as we presently projected but with fewer impacts from climate change, water scarcity and loss of ecosystems.
At present, the world is not on track to meet the SDGs by 2030 or 2050. Urgent action is required now as any delay in climate action increases the cost of achieving the goals of the Paris Agreement, or reversing our progress and at some point, will make them impossible.
The report advises adopting less-meat intensive diets, and reducing food waste in both developed and developing countries, would reduce the need to increase food production by 50% to feed the projected 9-10 billion people on the planet in 2050. At present, 33 per cent of global edible food is wasted, and 56 per cent of waste happens in industrialized countries, the report states.
While urbanization is happening at an unprecedented level globally, the report says it can present an opportunity to increase citizens’ well-being while decreasing their environmental footprint through improved governance, land-use planning and green infrastructure. Furthermore, strategic investment in rural areas would reduce pressure for people to migrate.
The report calls for action to curb the flow of the 8 million tons of plastic pollution going into oceans each year. While the issue has received increased attention in recent years, there is still no global agreement to tackle marine litter.
The scientists note advancements in collecting environmental statistics, particularly geospatial data, and highlight there is huge potential for advancing knowledge using big data and stronger data collection collaborations between public and private partners.
Policy interventions that address entire systems – such as energy, food, and waste – rather than individual issues, such as water pollution, can be much more effective, according to the authors. For example, a stable climate and clean air are interlinked; the climate mitigation actions for achieving the Paris Agreement targets would cost about US$ 22 trillion, but the combined health benefits from reduced air pollution could amount to an additional US$ 54 trillion.
The report shows that policies and technologies already exist to fashion new development pathways that will avoid these risks and lead to health and prosperity for all people,
said Joyeeta Gupta and Paul Ekins, co-chairs of the GEO-6 process.
What is currently lacking is the political will to implement policies and technologies at a sufficient speed and scale,
The sixth Global Environmental Outlook has been released while environmental ministers from around the world are in Nairobi to participate in the world’s highest-level environmental forum. Negotiations at the Fourth UN Environment Assembly are expected to tackle critical issues such as stopping food waste, promoting the spread of electric mobility, and tackling the crisis of plastic pollution in our oceans, among many other pressing challenges.
Total 332 Bird Species Located in Himachal Pradesh
Shimla-As per the Great Backyard Bird Count (7th Indian edition), the number of bird species in Himachal Pradesh was 332 in 2018, a spokesman of State Forest Department informed on February 21, 2019.
PCCF (WL) Dr. Savita said that among the Indian States, Himachal Pradesh shared the topmost position with Uttrakhand where the highest number of species was recorded.
Birding locations included wildlife sanctuaries, national parks, conservation reserves, villages and urban areas. She said that more than 150 bird species were recorded in Mandi, Shimla, Kangra and Sirmaur districts.
The Great Backyard Bird Count is a citizen science initiative intended to encourage both amateur and professional bird-watchers to contribute towards the understanding bird and their biology in a better way.
The Department said that amateur birders from across the state contributed in the count in addition to 287 checklists that were uploaded into e-Bird by 55 participants.
Participation in the event involved a minimum of 15 minutes bird watching during which all the bird species seen were counted and listed. It involved bird watching sessions with school teachers and students, birding involving local villagers and panchayat representatives and training of frontline staff of the forest department in bird identification.
The Department said a detailed report is in preparation and will be circulated by the first week of March
This initiative was coordinated by Joint Secretary (Forests) Sat Pal Dhiman, Chief Conservator Forest (HQR) Nagesh Guleria, Chief Conservator Forest (WL) South Sushil Kapta, DFO (Hqr) N.P.S. Dhaulta along with other senior officers of the department.
Watch: IIT Mandi Researchers Use ‘Pollutant Diesel Emissions’ For Water Treatment
Mandi- Researchers at Indian Institute of Technology Mandi have used the soot emitted by diesel engines to mop up oil and other organic pollutants from water. Their work has been recently published in the journal – Environmental Science and Pollution Research.
Although diesel engines are known to be superior to other internal combustion engines in terms of lower fuel consumption and better energy release efficiencies, they are associated with significant amounts of particulate emissions.
The particulates largely comprise soot, which is formed in the fuel rich regions of the burning diesel jets. Increasing environmental concerns and stringent emission standards require the development of both conventional and unconventional means for reducing soot.
Studies in this area have focused on improving the engine design and incorporating special filters and treatment units at the exhaust end of the vehicle.
Dr. Rahul Vaish, Associate Professor, School of Engineering at IIT Mandi and his research students Vishvendra Pratap Singh and Moolchand Sharma have looked at this problem from a different perspective.
They rationalized that while it is impossible to bring down soot emissions to zero, it is possible to find a use for the soot produced.
Carbon species such as carbon nanotubes, graphene, and candle soot have shown their potential in many fields,
so why not automobile soot?
It is known that carbon species can absorb various organic pollutants in water. Carbon nanotubes, filter paper, mesh films, and graphene have been used for removing oil from water. Given that the typical carbon content of soot is between 90 and 98%, the team explored the possibility of using this pollutant as an adsorbent of oil and organic contaminants in water.
There is a rapid increase in oil and chemical leakages from oil tankers or ships and industrial accidents with expansion in oil production and transportation in the last few decades,
the authors write in their recently published paper, justifying the need for new materials to mop up oil and prevent catastrophic environmental outcomes.
In an earlier study, Dr. Vaish used candle soot to successfully remove two cationic dyes, rhodamine B and methylene blue from water, thereby showing the possibility of organic from water thereby showing the possibility of organic chemical removal by soot. Extending this earlier work, the research team incorporated diesel exhaust soot into polymer sponges to study their capability to adsorb oil and other organic materials from water. This hydrophobic sponge showed high absorption capacity for various oils, without the need for complex pretreatments.
The researchers found that the highest oil absorption capacity was 39 g/g for engine oil. An interesting observation was that the sponges were recyclable and retained 95% efficiency even after 10 cycles.
The diesel soot impregnated sponge could also absorb pollutants like methylene blue, ciprofloxacin, and detergent from the water. This has practical implications.
Apart from oil spills, organic pollutants such as traces of dyes and detergent coming from industries and households are a major contributor to water pollution,
says Dr. Vaish.
The soot impregnated sponge can help in developing cost-effective remediation processes for common domestic and industrial pollutants. Such a development would additionally serve to repurpose automobile waste.
