Scientists from Anna University studied groundwater samples taken before and after Chennai floods of December 2015 to probe effect of floods on water quality

New Delhi: A new study has pointed out that flooding in polluted rivers has the potential to make groundwater unsafe for human use.

In December of 2015, when Chennai was flooded and people were marooned, a team of scientists from Anna University was collecting groundwater samples along the Adyar river to investigate if the groundwater in this region was fit for human consumption.

Researchers collected water samples from 17 locations in December 2015 and April 2016, that is, during and after floods. They tested the samples for salt and heavy metal concentration, microbial load and their susceptibility to available antibiotics.

“We wanted to know if the city water met water quality parameters laid down by the Bureau of Indian Standards during and post-flood”, Lakshmanan Elango, professor at the Department of Geology of Anna University, who led this study, told India Science Wire.

The results showed that heavy metal and microbial load in groundwater samples was high. The samples contained microbes such as Enterobacter, Staphylococcus, Escherichia, Streptococcus, Vibrio, and Salmonella that are known to cause infections like dysentery, cholera, and typhoid in humans. These microbes were cultured with various antibiotics used in clinical practice to treat life-threatening infections, to know they were susceptible or resistant to drugs.

“The bacteria were sensitive to most antibiotics but some were resistant to nalidixic acid, which is alarming as antibiotic resistance can rapidly spread in the environment”, said Prof Elango. The results of the study have been published in journal Nature Scientific Data.

In addition, scientists found high genetic similarity between bacteria from various locations implying that they must have originated from a single domestic sewage source containing fecal matter. “Sewage must have washed off with flood water, which in turn inundates the wells that would have resulted in contaminating the ground water”, believes Prof Elango.

“Our findings show that floods have the potential to impact the microbial quality of ground water in affected areas. Based on our study, we advise that wells must be chlorinated and the public must be warned to avoid consuming ground water for drinking, at least for some months post floods”, he added.

The research team included Ganesan Gowrishankar, Ramachandran Chelliah, Sudha Rani Ramakrishnan, Vetrimurugan Elumalai, Saravanan Dhanamadhavan, Kartikeyan Brindha, Usha Antony, and Lakshmanan Elango. It was done in collaboration with the University of Zululand in South Africa and the National University of Singapore, and was funded by the Department of Science and Technology (DST).

Renaming MGNREGA removes core spirit of rural employment law, says Shashi Tharoor

Published

Shashi Tharoor

Congress MP Shashi Tharoor has strongly criticised the renaming of the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA), saying the move strips the rural employment programme of its core essence. His remarks came after Parliament cleared the Viksit Bharat Guarantee for Rozgar and Ajeevika Mission (Gramin) Bill, also referred to as the VB-G RAM G Bill.

Speaking to media, Tharoor said the decision to remove Mahatma Gandhi’s name from the scheme “takes out the heart” of the rural employment programme that has been in place for years. He noted that the identity and philosophy associated with Mahatma Gandhi were central to the original law.

Tharoor also objected to the way the new name was framed, arguing that it unnecessarily combined multiple languages. He pointed out that the Constitution envisages the use of one language in legislation, while the Bill’s title mixes English and Hindi terms such as “Guarantee”, “Rozgar” and “Ajeevika”, along with the conjunction “and”.

‘Disrespect to both names’

The Congress leader said that inserting the word “Ram” while dropping Mahatma Gandhi’s name amounted to disrespecting both. Referring to Mahatma Gandhi’s ideas, Tharoor said that for Gandhi, the concepts of Gram Swaraj and Ram Rajya were inseparable, and removing his name from a rural employment law went against that vision.

He added that the name of Lord Ram could be used in many contexts, but questioned the rationale behind excluding Mahatma Gandhi from a programme closely linked to his philosophy of village self-rule.

Protests over passage of the Bill

The VB-G RAM G Bill was passed by the Lok Sabha on December 18 and cleared by the Rajya Sabha in the early hours of December 19 amid protests from Opposition members. Several MPs opposed the manner in which the legislation was pushed through, with scenes of sloganeering and tearing of papers in the House.

Outside Parliament, members of the Trinamool Congress staged a sit-in protest near Samvidhan Sadan against the passage of the Bill. Congress also announced nationwide protests earlier this week, accusing the government of weakening rights-based welfare schemes.

Despite opposition criticism, the government has maintained that the new law will strengthen rural employment and livelihood security. The Bill raises the guaranteed employment from 100 days to 125 days per rural household and outlines a 60:40 cost-sharing formula between the Centre and states, with a higher central share for northeastern, Himalayan states and certain Union Territories.

Rahul Gandhi attacks G RAM G bill, says move against villages and states

Rahul Gandhi has criticised the G RAM G bill cleared by Parliament, alleging it dilutes the rights-based structure of MGNREGA and centralises control over rural employment.

Rahul Gandhi

Leader of the Opposition Rahul Gandhi has launched a sharp attack on the Modi government after Parliament cleared the Viksit Bharat Guarantee for Employment and Livelihood Mission (Rural) Bill, commonly referred to as the ‘G RAM G’ bill. He described the proposed law as “anti-state” and “anti-village”, arguing that it weakens the core spirit of the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA).

The new legislation, which is positioned as an updated version of MGNREGA, was passed amid protests by opposition parties and is expected to replace the existing scheme once it receives presidential assent.

‘Bulldozed without scrutiny’, says Rahul Gandhi

Rahul Gandhi criticised the manner in which the bill was cleared, saying it was pushed through Parliament without adequate debate or examination. He pointed out that the opposition’s demand to refer the bill to a standing committee was rejected.

According to him, any law that fundamentally alters the rural employment framework and affects crores of workers should undergo detailed scrutiny, expert consultation and public hearings before approval.

Claim of dilution of rights-based guarantee

Targeting the central government, the Congress leader said the proposed law dismantles the rights-based and demand-driven nature of MGNREGA and replaces it with a rationed system controlled from Delhi. He argued that this shift undermines the autonomy of states and villages.

Rahul Gandhi alleged that the intent behind the move is to centralise power and weaken labour, particularly impacting rural communities such as Dalits, OBCs and Adivasis.

Defence of MGNREGA’s impact

Highlighting the role of MGNREGA, Gandhi said the scheme provided rural workers with bargaining power, reduced distress migration and improved wages and working conditions, while also contributing to rural infrastructure development.

He also recalled the role of MGNREGA during the Covid period, stating that it prevented crores of people from slipping into hunger and debt. According to him, any rationing of a jobs programme first affects women, landless workers and the poorest communities.

Opposition to name change and provisions

The Congress has also objected to the renaming of the scheme, accusing the government of attempting to erase the legacy associated with Mahatma Gandhi. Opposition MPs staged a dharna within the Parliament complex, questioning provisions of the bill that they claim dilute the “soul and spirit” of the original law enacted in 2005.

Under MGNREGA, the government guaranteed 100 days of work in rural areas along with an unemployment allowance if work was not provided. The ‘G RAM G’ bill proposes to raise the guaranteed workdays to 125, while retaining other provisions. However, critics have flagged concerns over employment being linked to pre-approved plans.

The bill was cleared after a midnight voice vote in the Rajya Sabha, following its passage in the Lok Sabha amid protests and walkouts. It will become law once approved by the President.
