Welcome to your Rajasthan daily current affairs notes for 25 June 2026, prepared for RAS/RPSC and all State PCS aspirants. Today’s edition covers a low-cost lead-detection water sensor built at the Central University of Rajasthan, the constitution of the state’s Uniform Civil Code drafting committee, the 6th Solar and Storage Expo at Jaipur that spotlights Rajasthan’s renewable lead, out-of-turn government jobs for medal-winning athletes, the progress of Rising Rajasthan investments, and the status of the Ramjal Setu (PKC-ERCP) river-link project. Each item is mapped to the RPSC Prelims and Mains syllabus with a ready Fact File and five practice MCQs.
1. CURAJ Develops Low-Cost Sensor to Detect Lead in Drinking Water
Why in News: On 22 June 2026, researchers at the Central University of Rajasthan (CURAJ), Kishangarh (Ajmer district), announced a highly sensitive, low-cost electrochemical sensor that detects minute traces of toxic lead (Pb2+) ions in drinking water without any added chemicals, buffers or reagents.
Background: The project was led by Dr Pankaj Gupta of the Chemistry Department at CURAJ, in collaboration with the Finnish nanotechnology firm CANATU. The electrodes were tested on tap water and on river-water samples, and the device is meant for use at household water lines, municipal water-delivery stations and water-treatment plants. Lead contamination is hard to spot because it does not change the colour or smell of water, yet it harms the nervous system and is especially dangerous to children’s brain development. An affordable Rajasthan-built tool is significant for a state with large rural and desert habitations dependent on piped supply. This connects to Rajasthan science and technology and public health.
RPSC Relevance: Prelims, location of CURAJ (Bandarsindri, Kishangarh, Ajmer district, a Central University), heavy-metal contamination and water quality. Mains GS3, science and technology indigenisation, water safety and rural health; GS1 social geography of desert water dependence.

2. Rajasthan Constitutes Uniform Civil Code Drafting Committee
Why in News: The Rajasthan government has constituted a committee headed by former Supreme Court judge Justice Ranjana Prakash Desai to prepare the statutory draft of the Rajasthan Uniform Civil Code, 2026. The constitution of the panel was announced in the third week of June 2026 by Law Minister Jogaram Patel.
Background: The Cabinet had cleared the move to proceed towards a Uniform Civil Code in its meeting chaired by the Chief Minister on 14 April 2026, making Rajasthan one of the BJP-ruled states to initiate the process after Uttarakhand. Apart from Justice Desai, the panel includes retired IAS officer Shatrughna Singh, Additional Advocate General Basant Singh Chhaba, former law-college principal Ramswaroop Agarwal and Dr Shuchi Chauhan, with the Additional Chief Secretary (Home) as Member-Secretary. The committee will hold divisional-level consultations and accept public suggestions online before drafting provisions on marriage, divorce, inheritance and related personal-law matters. This connects to Rajasthan polity and governance.
RPSC Relevance: Prelims, Article 44 (Directive Principle on UCC), committee head and composition. Mains GS2, Directive Principles, personal laws versus uniform code, federal and social dimensions; ethics of consultation and inclusivity.

3. Solar and Storage Expo 2026 Spotlights Rajasthan’s Renewable Lead
Why in News: The 6th edition of the Solar and Storage Expo Rajasthan 2026 is being held on 25 June 2026 at The Lalit, Jaipur, bringing together developers, policymakers and investors, and presenting the Rajasthan Energy Excellence Awards 2026.
Background: The expo features dedicated forums such as the PM-KUSUM Meet, PM Surya Ghar Meet, Energy Storage Meet and Net-Zero Meet. Rajasthan continues to lead India in installed solar capacity, with state solar capacity crossing 30 GW, anchored by the Bhadla Solar Park in Jodhpur (one of the world’s largest). The state targets large-scale renewable additions by 2030, leveraging its high solar irradiance in the western desert districts of Jaisalmer, Bikaner, Jodhpur and Barmer. This connects to Rajasthan renewable energy and infrastructure.
RPSC Relevance: Prelims, Bhadla Solar Park location, PM-KUSUM and PM Surya Ghar schemes, Rajasthan’s rank in solar capacity. Mains GS3, energy security, renewable transition, battery storage and grid integration.
| Prelims Fact | Detail |
|---|---|
| Event | Solar and Storage Expo Rajasthan 2026 (6th edition) |
| Venue and date | The Lalit, Jaipur, 25 June 2026 |

4. Medal-Winning Athletes to Get Out-of-Turn Government Jobs
Why in News: In late June 2026, the Rajasthan government approved the induction of 50 medal-winning athletes into state government service under the out-of-turn appointment policy, with allotment to the School Education Department as junior assistants.
Background: The athletes won medals at National Championship and National Para Championship events. Under Rajasthan’s out-of-turn appointment policy for sportspersons, medallists are directly inducted into gazetted and non-gazetted posts, bypassing routine recruitment delays, and the state has used the policy to absorb a large number of athletes so far. The decision reflects the government’s stated priority of making Rajasthan a sporting hub, complemented by upgradation of facilities such as the Sawai Mansingh Stadium in Jaipur. This connects to Rajasthan sports policy and governance.
RPSC Relevance: Prelims, out-of-turn appointment policy, allotting department. Mains GS2, welfare and incentive policy; GS3 sports development and human-resource policy.

5. Rising Rajasthan: Rs 15,000 Crore Investment Realised in Mining and Petroleum
Why in News: Officials reviewing the Rising Rajasthan investment pipeline in June 2026 confirmed that projects worth about Rs 15,000 crore have moved from MoU stage to on-ground investment in the mining and petroleum sectors, with a further Rs 6,500 crore in projects nearing completion.
Background: The Rising Rajasthan Global Investment Summit, held in Jaipur in December 2024, generated MoUs across mining, petroleum, cement, copper and renewable sectors. The realisation update is part of the government’s effort to convert investment intent into operational projects. Flagship completions include UltraTech’s cement plant (about Rs 2,230 crore), Hindustan Copper’s expansion at the Khetri unit (about Rs 1,000 crore) and Indian Oil’s crude-oil pipeline (about Rs 3,600 crore). This connects to Rajasthan economy and industrial development.

6. Ramjal Setu (PKC-ERCP) River-Link Project Progress
Why in News: The Modified Parbati-Kalisindh-Chambal-Eastern Rajasthan Canal Project, renamed the Ramjal Setu Link Project, remains in active implementation in 2026 as a National Perspective Plan river-interlinking scheme jointly executed by Rajasthan, Madhya Pradesh and the Centre.
Background: A tripartite MoU among Rajasthan, Madhya Pradesh and the Government of India had been signed earlier to merge the Parbati-Kalisindh-Chambal (PKC) link with the Eastern Rajasthan Canal Project (ERCP). The Chief Minister renamed it the Ramjal Setu Link Project on the first anniversary of the Ayodhya Ram Mandir consecration. The project aims to provide drinking, industrial and irrigation water to about 13 to 21 eastern Rajasthan districts, supporting roughly 1.5 crore people, while concerns persist over submergence near the Ranthambhore Tiger Reserve. This connects to Rajasthan water resources and irrigation.
RPSC Relevance: Prelims, rivers Parbati, Kalisindh and Chambal; ERCP and its renaming; National Perspective Plan for interlinking. Mains GS1 and GS3, inter-state river management, drought-proofing eastern Rajasthan, environment versus development trade-offs.
