This annual overview compiles the top ten reports showing the rising contamination of groundwater resources in India during 2024. It includes some shocking facts from Punjab, Himachal Pradesh, Haryana, Gujarat, Telangana, Kerala, Ladakh, Assam, Chhattisgarh, Karnataka and W Bengal, in addition to reports from CGWB (Central Ground Water Board) a Parliamentary Committee. The contaminants reported in groundwater include nitrates, fluorides, arsenic, uranium, heavy metals (Chromium, cadmium, nickel, manganese, selenium, among others), Iron, salinity, among others. Since most people consume groundwater assuming it to be safe, what is reported here is only a tip of the proverbial toxic-berg. The easiest way forward, besides more regular monitoring and improved governance is rainwater harvesting on war footing. However, the government, busy pushing more big dams and interlinking projects, has little real priority for that.

Groundwater 2024: Increasing Impacts of Climate Change

January 27, 2025 SANDRPLeave a comment

Several studies and reports published during 2024 have underlined the rising adverse impacts of changing climate on groundwater resources in India and globally in multiple ways which will continue to accelerate in future. While the groundwater greatly contributes to river baseflows during lean period, its role in flooding is miniscule comparatively with surface flows in Peninsular India. In North India the drying northwest monsoon and warmer winters have been found driving groundwater depletion by raising demand for irrigation water.

The groundwater is getting warmer, also impacting subterranean aquatic ecosystems. Besides, the rising temperatures are causing more evaporation losses and leading to pumping of more groundwater to compensate for the losses. The extreme rainfall events might speed up fertilizers seeping into groundwater table contaminating it. Similarly, the rising sea level is found fueling erosion in coastal areas and facilitating seawater intrusion of the coastal aquifers. At the same time the decline in low and medium intensity rainfall and warmer weather patterns are reducing groundwater recharge, increasing seawater ingress.

A detailed report in this week’s DRP News Bulletin below shows how India’s Sewage Treatment Plants (STPs), Govt’s main weapon against pollution of rivers in Urban areas, have been a failure for decades. It is pertinent to note that this is the golden jubilee year of Water Pollution Control Act of 1974, that led to the formation of Central, state Pollution Control Boards, and the whole water pollution control bureaucracy, institutions and legal architecture. There should be little doubt that whole architecture has abysmally failed in achieving basic objective for which it was created, including ensuring proper treatment of urban sewage.

India has spent thousands of crores of rupees on these STPs, mostly, mega, centralized projects. But there has been little effort to address governance of the STPs, to ensure that they function as required and provide the results that they have been set up for. Whether they function or not, qualitatively or quantitatively, year after year and decades after decades, there are no consequences! In fact, if treated properly, sewage can become a asset rather than nuisance that it now is. The Judiciary too, right up to the apex court, have badly failed in achieving any improvement in this eminently justiciable issue.

DRP 200125: Whither Env Clearance Rejection rate from Expert Appraisal Committee or MoEF?

January 20, 2025February 28, 2026 SANDRPLeave a comment

A detailed review of functioning of Union Ministry of Environment and Forests’ (MoEF) Expert Appraisal Committee (EAC) on River Valley Projects (RVP) for 2024 by SANDRP shows that the committee or for that matter MoEF has almost non-existent rejection rate. Even when a project is not cleared, when it applies again, it gets clearance, whether the application if for stage I (Terms of Reference) or Stage II (Environment Clearance- EC) clearance. Even in some cases like Pump Storage Projects (PSP) in Western Ghats or the Hydropower projects in disaster prone Himalayas, including the disaster-stricken projects like the 1200 MW Teesta III projects in Sikkim, the scrutiny including field visits by the EAC Sub committees is minimal, not worthy calling even scrutiny.

DRP 130125: Will Judiciary take these matters to logical conclusion?

January 13, 2025February 28, 2026 SANDRPLeave a comment

There are at least four cases in this past week where the judiciary has used strong words or taken up crucial issues in water, dams, hydropower projects, wetlands and riverbed mining related issues. In the case related to the safety of Mullaperiyar dam on Kerala-TN border, the Supreme Court has prodded the Centre to wake up from the slumber to ensure that National Dam Safety Authority quickly forms a panel to examine the project. This case has wide ranging repercussions not only about this project, but also functioning of NDSA and other bodies under the Dam Safety Act 2021. Indeed, there is huge question mark as to what extent NDSA and DSA has made our dams any safer.

DRP 060125: Concerns about & Contradictions in CGWB’s Reports

January 6, 2025February 28, 2026 SANDRPLeave a comment

The Central Ground Water Board (CGWB) released two important reports last week. While the Annual Ground Water Quality Report 2024 reveals rise in nitrate fluoride, arsenic and uranium contimination of groundwater resource in India, the Dynamic Groundwater Resource Assessment Report 2024 claims substantial rise in annual groundwater recharge and decline in extraction of the resource.

As per the first report, the number of districts affected by high nitrate levels in groundwater has gone up to 440 (near 56% of all 779 districts in country) from 359 found in 2017 assessment which means in 7 years 81 more districts have been found having excessive nitrate levels in groundwater. This should concern us from a number of points of view.

This twelfth edition of monthly Yamuna updates and the first one of the new year 2025, rounds up the critical issues impacting the river eco-system during the past year. The updates of the past one month only hint towards the bleak future the river is heading to. Without addressing the adverse effects and exploring cost effective alternatives, foundation stones of two massive river interlinking projects namely Ken-Betwa and Parbati-Kalisindh-Chambal have been laid. The work of unjustifiable Renuka and Lakhwar dams in climatically sensitive and geologically fragile region of Himalaya is going on.

Exactly three months back, on Sept 30 2024, we had highlighted the urgent need for credible river studies in India (https://sandrp.in/2024/09/30/drp-nb-300924-focus-on-river-studies/). A new research report published last week in Nature has corroborated this, showing that volume of research across global south is disproportionately small compared to need based on basic population, water withdrawals and water consumption.

Based on review of 4237 publications using machine learning and desk review of 325 publications, analysis of 4713 case studies across 286 basins, it shows that river research currently in global south is predominantly led by global North institutions, thus the river research is shaped by selection of theme and locations done by such institutions.

It is indeed good to see an Editorial in a newspaper on the important issue of wetlands protection and rejuvenation. The Supreme Court’s order on wetlands last week shows its concern over the threat to wetlands as a natural feature of the environment that is under serious threat. The court ordered the protection of about 30,000 wetlands (each with area more than 2.25 ha) over the 201,503 protected by an order which it issued in 2017, and asked states to ensure their demarcation and ground-truthing which involves closer verification, within three months.

The order is in response to a PIL that said the Central government had abdicated its functions under the Environment Protection Act, 1986, to protect the wetlands. The petition also sought the identification and protection of around 5,55,557 wetlands which are less than 2.25 hectares in size. The court is likely to consider the proposal in March. One hopes the SC also gives effective orders for their protection.

Hundreds of People of Siang, East Siang and Upper Siang Districts of Arunachal Pradesh came out in peaceful protests on Dec 14 2024. They opposed the govt effort to deploy armed central and state police forces for a pre-feasibility study for the 12500 MW hydropower project on Siang River, a tributary of Brahmaputra River.

Indeed, as remarkably articulate report by in Arunachal Times said, Siang needs dialogue not guns. In fact, the Chief Minister recently and even the Prime Minister and Union Home Minister had earlier promised to the people of the state that if they do not want big dams, such projects will not be taken without people’s consent as there were options for power and development.
