(d) whether the Government has undertaken any recent studies or assessments on groundwater contamination in Rajasthan and if so, the key findings thereof?

## ANSWER

## THE MINISTER OF STATE FOR JAL SHAKTI

## ( SHRI RAJ BHUSHAN CHOUDHARY )

(a) At present, 26 Scientific Officers of various disciplines (i.e Hydrogeology/ Geophysics/ Chemical/Hydrometeorology)  are  posted  under  CGWB,  Western  Region,  Jaipur.  Further,  since  the  year 2019,  CGWB has dispensed with the system of allocating office wise strength and officers  are  posted  in different offices of CGWB as per the requirement.

(b) Dynamic Ground Water Resources of the country including for the state of Rajasthan, are being assessed annually,  jointly  by  Central  Ground  Water  Board  (CGWB)  and  State  Governments.  As  per  the  latest assessment of 2025, the total annual ground water recharge for the state of Rajasthan is 12.87 Billion Cubic Meters (BCM) and total annual ground water extraction is estimated as 17.10 BCM. Similarly, for Barmer district, the total annual ground water recharge is 0.385 BCM and Extraction is 0.469 BCM.

Regarding categorization of units in terms of their stage of ground water extraction, out of the total 302 Assessment Units (Blocks) in Rajasthan, 213 (70.53%) units have been categorized as 'Over- exploited' indicating ground water extraction exceeding the annually replenishable ground water recharge and 23 units (7.62 %) have been categorized as 'Critical'. Further, in Barmer district, 12 units are in Over-exploited and 2 units are in Critical category.

Water  being  a  State  subject,  sustainable  development  and  management  of  groundwater  resources  is primarily  the  responsibility  of  the  State  Governments.  However,  the  Central  Government  facilitates  the

efforts of the State Governments by way of technical and financial assistance through its various schemes and projects. In this direction, several significant steps have already been taken by the Ministry of Jal Shakti and other central ministries for sustainable development of ground water resources in the country, including Rajasthan. Some of the important ones are given below:-

- i. Efforts of the Central government for augmenting the water/groundwater resources of the country, are mainly channeled through the flagship campaign of Jal Shakti Abhiyan (JSA). JSA is a time bound and mission mode programme being conducted annually since 2019 by the M/o Jal Shakti, wherein all the efforts and funds under various schemes and projects are converged to deliver water harvesting and artificial recharge works on the ground.

Currently,  JSA  2025  is  underway  in  the  country  with  special  focus  on  over-exploited  and critical districts. As per the available information, under JSA, completion of around 1.21 crore water conservation and artificial recharge works has been coordinated through convergence in the country in the last 4 years, with 6.54 lakh structures in Rajasthan & 1.65 lakh structures in Barmer, which has played a key role in enhancing the sustainability of ground water resources.

- ii. To further  strengthen  the  momentum  of  Jal  Shakti  Abhiyan,  Jal  Sanchay  Jan  Bhagidari  (JSJB):  A Community-Driven Path to Water Sustainability in India has been launched by the Hon'ble Prime Minister with a vision to make rain water harvesting a mass movement in the country. By promoting community ownership and responsibility, the initiative seeks to develop cost-effective, local solutions tailored to specific water challenges across different regions.
- iii. M/o  Jal  Shakti  has  successfully  demonstrated  the  efficacy  of  community  led  participatory  ground water management through Atal Bhujal Yojana, which was implemented in 80 water stressed districts in 7 States, including Rajasthan. Construction of various rain water harvesting and recharge structures like check dams, ponds, shafts etc. as well as promotion of micro irrigation was taken up under the scheme with an objective to augment the ground water resources and to reduce the strain on them through efficient water management practices.
- iv. Mission  Amrit  Sarovar  was  launched  by  the  Government  of  India  which aimed  at  developing  and rejuvenating at least 75 water bodies in each district of the country. As an outcome nearly 69,000 Amrit Sarovars have been constructed/rejuvenated in the country, with 3,138 in Rajasthan and 97 in Barmer, leading to enhanced water storage and ground water recharge.
- v. CGWB has also prepared the Master Plan for Artificial Recharge to Groundwater- 2020, for the entire country  providing  a  broad  outline  for  construction  of  around  1.42  crore  rain  water  harvesting  and artificial  recharge  structures  in  the  country  to  harness  185  BCM  (Billion  cubic  meter).  The  Master Plan  recommends  construction  of  about  7.70  lakhs  rainwater  harvesting  and  artificial  recharge

structures for Rajasthan, including Barmer, like Contour bunds, Check Dams, Injection wells, SubSurface Dykes etc.

- vi. CGWB has  taken  up  National  Aquifer  Mapping  and  Management  Programme  (NAQUIM)  under Ground  Water  Management  &  Regulation  (GWM  &R)  Scheme  with  an  aim  to  delineate  aquifer disposition and their characterization. Entire mappable area of the country of around 25 lakh sq. km, including 3.42 sq. km in Rajasthan, has been mapped under the scheme and district-wise management plans have been shared with the respective State/District administrations for implementation.
- vii. M/o Jal Shakti is promoting conjunctive use of surface water and groundwater and to reduce overdependence on groundwater, surface water based Major and Medium irrigation projects have been taken up in the country under PMKSY-AIBP scheme in collaboration with States/UTs.

(c) As informed by the CGWB, no infrastructure deficiencies are being faced by CGWB scientists in Jaipur, Rajasthan and the  availability  of  scientific  equipment  is  adequate  to  carry  out  field  studies.  However,  the Ministry has taken proactive steps to improve the infrastructure and logistics availability to all the offices of CGWB including that of Jaipur, Rajasthan.

(d) Central  Ground  Water  Board  (CGWB)  generates  ground  water  quality  data  of  the  country,  including Rajasthan as part of its ground water quality monitoring program and various scientific studies conducted as per the approved Standard Operating Procedure (SOP). Overall, the data on ground water quality indicates that  the  ground  water  in  Rajasthan  remains  largely  potable  with  localized  occurrences  of  contaminants  in isolated pockets.

Findings  of  the  Annual  Ground  Water  Quality  Report  2025,  regarding  localized  occurrence  of contaminants such as fluoride, iron, salinity, nitrate etc. in Rajasthan are summarized in Annexure.
