Jerusalem, Aug 25: Wastewater containing coronaviruses, such as the one behind the Covid-19 pandemic, may be a potential threat, according to a new review of studies that calls for additional filtration steps in sewage treatment plants to successfully remove viruses.

The research, published in the journal Nature Sustainability, by an international collaboration of 35 researchers, assessed recent studies on coronaviruses in wastewater.

According to the review research, conventional wastewater treatment provides only partial removal of coronaviruses, with safe disposal or reuse depending on the effectiveness of final disinfection.

"There is ample reason to be concerned about how long coronaviruses survive in wastewater and how it impacts natural water sources," said study lead author Edo Bar-Zeev from the Ben-Gurion University of the Negev (BGU) in Israel.

"Can wastewater contain enough coronaviruses to infect people? The simple truth is that we do not know enough and that needs to be rectified as soon as possible," Bar-Zeev said.

According to the scientists, sewage leaking into natural watercourses might lead to infection with the novel coronavirus SARS-CoV-2 via airborne spray.

They said treated wastewater used to fill recreational water facilities, like lakes and rivers, could also become sources of contagion, adding that fruits and vegetables irrigated with this water may also be an indirect infection route.

The scientists recommended immediate, new research to determine the level of potential infection, if any, and how long coronaviruses last in various bodies of water and spray.

"Wastewater treatment plants need to upgrade their treatment protocols and in the near future also advance toward tertiary treatment through micro- and ultra-filtration membranes, which successfully remove viruses," the scientists noted.

They added that wastewater can also be used to monitor or track Covid-19 outbreaks.

Using a new methodology, the researchers recently detected and traced the presence of the novel coronavirus, and calculated its concentration to pinpoint emerging Covid-19 hotspots.

Mangaluru City Corporation Mayor Manoj Kumar issued a stern directive to GAIL Gas Limited, instructing them to immediately restore roads damaged during their ongoing gas pipeline project.

The issue, which has left motorists and residents frustrated, dominated discussions at a special meeting chaired by the mayor on Monday. Corporators unanimously criticized the delay in road restoration, with Opposition Leader Anil Kumar warning that the project should be halted if the roads remain neglected.

Corporator Naveen D’Souza pointed out that permissions granted for the pipeline project were limited to two years, yet the roadwork disruption has dragged on for over five years. He demanded criminal charges and penalties against responsible officials for the prolonged inconvenience.

Adding to the outcry, Corporator Sangeetha Nayak called for MCC engineers to inspect the affected areas, while Corporator Varun Chowta flagged a severe lack of coordination between MCC, GAIL, and Jalasiri 24x7 officials.

The mayor directed GAIL Gas Limited to submit a report within two days addressing the complaints raised. He also insisted on a detailed update on the project’s implementation to be presented at the next review meeting, aiming for a resolution to the ongoing chaos.

In a significant milestone, the Dakshina Kannada Zilla Panchayat Higher Primary School in Newpadpu, Harekala, has introduced a bilingual Kannada-English medium this academic year, a move spearheaded by Padma Shri awardee Harekala Hajabba. The school has so far received 13 admissions for its Class 1 bilingual program.

This initiative is part of a broader effort by the state government, which approved 38 schools across the district to launch bilingual mediums. Expressing his delight, Hajabba shared that he had been advocating for a bilingual school for years. "The bilingual medium will greatly benefit students in this region who otherwise rely on private schools. However, we currently face a shortage of classrooms. Construction of two additional classrooms is underway, and once completed, we expect higher admissions," he said.

The school had previously been permitted to introduce LKG and UKG classes in the last academic year. According to the school’s headmistress, Rajeshwari, while the pre-primary sections have seen good enrolment, the bilingual Class 1 faced challenges, securing only 13 students. She attributed this to the late notification of permission, which arrived a month after the academic year began, leading many children to enroll elsewhere.

Rajeshwari remains optimistic about the future. "We expect better admissions next academic year as awareness about bilingual education at this government school grows," she said, adding that the classroom shortage will soon be addressed.

Deputy Director of Public Instruction (DDPI) Venkatesha Subraya Patagara noted that bilingual schools across Dakshina Kannada have generally received a positive response, with some schools enrolling more than 100 students. The effort to offer bilingual education in government schools marks a step forward in providing affordable, quality education to underserved regions.

New Delhi: The Union Cabinet on Thursday approved bills to implement 'One Nation, One Election', and the draft legislations are likely to be introduced in Parliament in the ongoing Winter session, sources said.

The decision was taken at a meeting of the Union Cabinet chaired by Prime Minister Narendra Modi.

The government is keen on holding wider consultations on bills which are likely to be referred to a parliamentary committee.

Sources said the government was also keen to consult the Speakers of various state legislative assemblies through the committee.

Moving ahead with its 'one nation, one election' plan, the government in September accepted the recommendations of the high-level committee for holding simultaneous polls for the Lok Sabha, state assemblies and local bodies in a phased manner.

Citing recommendations of the high-level committee, sources had said one of the proposed bills would seek to amend Article 82A by adding sub-clause (1) relating to the appointed date. It will also seek to insert sub-clause (2) to Article 82A relating to the end of terms of the Lok Sabha and state legislative assemblies together.

It also proposes to amend Article 83(2) and insert new sub-clauses (3) and (4) relating to the duration and dissolution of the Lok Sabha. It also has provisions related to the dissolution of the legislative assemblies and amending Article 327 to insert the term simultaneous elections.

This bill will not require ratification by at least 50 per cent of the states, the recommendation said.

However, any move to hold local body elections together with Lok Sabha and state assemblies will require ratification by at least 50 per cent of the state assemblies as it deals with matters relating to state affairs.

Another bill will be an ordinary one to amend provisions in three laws dealing with Union territories having legislative assemblies -- Puducherry, Delhi and Jammu and Kashmir -- to align the terms of these Houses with other legislative assemblies and the Lok Sabha as proposed in the first constitutional amendment bill.

The statutes it proposes to amend are the Government of National Capital Territory of Delhi Act-1991, the Government of Union Territories Act-1963 and the Jammu and Kashmir Reorganisation Act-2019.

The proposed bill will be an ordinary legislation not requiring a change in the Constitution and will also not need ratification by the states.

The high-level committee had proposed amendments to three Articles, insertion of 12 new sub-clauses in the existing articles and tweaking three laws related to Union Territories having legislative assemblies. The total number of amendments and new insertions stands at 18.

In its report submitted to the government in March, just before the general election was announced, the panel recommended implementing one nation, one election in two phases.
