Poison in India’s groundwater posing national health crisis

New Delhi, May 2: Depletion of groundwater and its increasing pollution could be leading to a silent, nationwide public health crisis as aquifers in many stretches across India are becoming unfit for drinking, according to the government's own figures.

Data submitted in Parliament by the water resources ministry on Monday shows groundwater in pockets of 158 out of the 639 districts has gone saline. It says in pockets across 267 districts, groundwater contains excess fluoride; in 385 districts, it has nitrates beyond permissible levels; in 53 there's arsenic and there's high level of iron in 270 districts.

Besides this, aquifers in 63 districts contain heavy metals like lead, chromium and cadmium, the presence of which in any concentration poses a danger.

The record submitted in answer to a question by Congress MP Shruti Chowdhry presents a countrywide map of where groundwater has become unfit for drinking and where contamination levels have breached government standards of safety.

In Delhi, a number of areas are not safe to draw groundwater from. Aquifers in north, west and southwest districts along the Najafgarh drain contain lead. The southwest district has cadmium and northwest, south and east Delhi have chromium, rendering the water not just bad but dangerous to drink.

Adding to the danger is the fact that only about 65% of the city's population (predominantly in the better-off localities) is serviced by the water supply system of Delhi Jal Board. Besides heavy metal contamination, fluoride has been found in aquifers in New Delhi and those in east, central, north, northwest, south, southwest and west Delhi.

Apart from these, areas in east, central, New Delhi, northwest, south, southwest and west contain nitrates.

The stealthily growing health crisis could be worse in rural India where facilities to even detect chronic health problems arising out of water contamination do not exist. Nearly 80% of India's rural drinking water comes from underground sources.

Drinking fluoride-laden water beyond safe levels can lead to fluorosis which hits teeth and bones. Arsenic causes problems in the nervous system, reduces IQ level in children and in extreme cases can also cause cancer. Chromium is a known carcinogen. Presence of nitrates in drinking water leads to what is commonly called as blue baby disease which hits infants and can lead to respiratory and digestive system problems.

These chemicals have appeared in the water sources either due to too much water being drawn from deeper and deeper in the ground, or due to industrial and human waste contamination.

Arsenic and fluoride are typically found in groundwater where chemicals have leeched from the bedrock due to over-exploitation of the source. Heavy metals are likely to flow in from industrial waste dumped untreated into water-systems. Nitrates are likely to appear in groundwater because of excess or repetitive use of fertilizers over time.

Government reports have shown that water withdrawal from underground aquifers is higher than the annual recharge levels in almost 15% of the country's geographical area. The number of wells are increasing rapidly and so are the depths to which people are plumbing to bring water out as the sources dry up.

India has jumped past 4.5 lakh coronavirus cases and 14,476 people have succumbed to the viral infection so far. In this backdrop, speaking to IANS in an exclusive interview, AIIMS Director Randeep Guleria said India is also vulnerable to second wave of coronavirus and people should continue to follow social distancing, wearing mask and other precautions, after cases begin to decline.

He added that in order to contain the outbreak of Covid-19, a limited lockdown in hotspots, where volume of cases is very high, may be considered along with a micro-plan to prevent leakage of cases from these areas to other non-containment areas. Excerpts of the interview are below:

Q: Reports say China and South Korea are witnessing a second wave of coronavirus infection, what is this second wave, is India also vulnerable to this?

A: When cases come down significantly, people tend to drop their guard against the viral infection, and this leads to the second wave (which means a sudden increase in the number of cases). After cases begin to decline, people should continue to follow the precautions -- continue to maintain social distancing and wear masks regularly. See what happened in Singapore, it was struck by a second wave of coronavirus. Look, what happened in the 1918 pandemic, people dropped their guard and the second wave of viral infection struck back. If people do not follow social distancing then the spike in cases is apparent. We need to take these precautions at least for one year. India is also vulnerable to this second wave.

Q: If Covid-19 cases continue to rise rapidly, do you think we need another lockdown in areas where volume of cases are very high?

A: A large volume of cases is concentrated in specific areas like hotspots, and in order to maintain things in order, we may need a limited lockdown in these areas. This should be followed by a micro-plan which entails extensive testing of people and also extensive contact tracing of people who have got in touch with positive people. Need to ensure there is no leakage of cases from these areas. People from these areas should not mix with others in non-containment areas. This will aid in containing the outbreak of the virus. People who have developed symptoms should get themselves tested, especially in the containment areas.

Q: With more than 4.5 lakh cases and close to 14,500 deaths, do you think India has reached its peak and a decline in cases is prominent?

A: The cases will continue to increase for some time. The doubling time of cases has also increased. But, the cases will also begin to flatten. Though, it is difficult to give an exact time period in this viral infection, it seems, the growth in cases will flatten in the end of July or beginning of August. A decline will come to this viral infection, but it does not mean that people should drop their guard. As a measure, we need to decrease community participation and citizens should continue to follow social distancing. People should get themselves tested. All these efforts will help in preventing people from contracting this virus. These precautions will also prevent us from the second wave, and we must continue to take precautions. The virus has not gone away, it is still lurking.

Q: India has crossed the 4.5 lakh coronavirus cases so far, although our recovery rate is good, but still 10,000 to 15,000 cases are reported daily. Why do cases continue to spiral, what is the reason?

A: We have to remember a few things -- the bulk of cases are in 10 cities, nearly 70 per cent, and if we take into account cases per million population, the number is not very high, as compared with countries including countries in Europe. Many European countries put together still do not add up to the Indian population. Do not compare India to countries like Italy, Spain etc. We need to focus on hotspots, which contribute to between 70 -80 per cent of cases, and we have to identify cases in these areas at an early stage. The population density is very high in these cities. People in lower socio-economic status are highly vulnerable to the viral infection, as many live together in small spaces and there is a lot of mixing of people happening there. Look at the market places, people are not following social distancing and not wearing masks. In fact, many are in close vicinity of each other.

Kochi, Apr 24: The central government on Thursday submitted a statement in the Kerala High Court on the three petitions challenging the contract between Kerala government and US-based data analytics company Sprinklr.

Assistant Solicitor General P Vijayakumar filed the statement on behalf of the central government, which is the second respondent in the case.

The statement said that the contract between the Kerala government and Sprinklr dilutes the rights of the people. It stated the contract does not specify the amount of compensation that individuals should receive in case of breach of privacy or misuse of information.

It also said that it was not clear whether the information was collected and handed over to the data analytics firm with full consent of the patients (suspected and otherwise).

''It is always preferable to utilise the services available in the government sector for sharing sensitive data required for analytical purposes.

The Government of India has introduced the 'Aarogya Setu' application for collection of health data and about seven crore Indian citizens have already downloaded the same. All the state governments are advised to promote the said application for fighting the pandemic," the statement said.

It was further submitted that the "Government of India with the support of NIC is capable of providing all the requirements relating to data storage, processing and application which are being offered the third respondent, if a request to that effect comes from the state government."

Kerala Congress leader Ramesh Chennithala and BJP state president K Surendran had earlier approached the Kerala High Court seeking cancellation of the state government's agreement with Sprinklr for processing of data related to COVID-19 patients.

New Delhi, Jul 22: India is responding with utmost urgency to coronavirus from the very beginning and has been continuously strengthening preparedness and response measures, WHO Regional Director (South-East Asia) Poonam Khetrapal Singh said on Wednesday.

"India is responding with utmost urgency to COVID-19 from the start. It's been continuously strengthening preparedness and response measures, including ramping up testing capacities, readying more hospitals, arranging and stocking up medicines and essentials," Singh said at a virtual briefing.

"India took bold, decisive and early measures earlier in the outbreak. The country did not witness an exponential increase in cases like some other countries which reported their first few cases along with India. Like in any other country the transmission of COVID-19 is not homogenous in India. There are areas yet to see a confirmed case, some have sporadic cases, in some areas some small clusters while we are witnessing large clusters in some megacities from the densely populated areas," Singh said.
She said WHO was aware of varying capacities at sub-national levels.

"Not unusual in a country as big as India and its population size that measures taken may often not be uniformly sufficient across all areas. Scaling up capacities and response remains a constant need in India."

Replying on the question of what more needs to be done in controlling the spread of COVID-19, she said all countries including India must continue to implement core public health and social distancing measures.

"Local epidemiology to guide our response for finding hotspots and testing, detecting, isolating and providing care to the affected, promoting safe hygiene practices and respiratory etiquette, protecting health workers and increasing health system capacity is also key," she said.
