Water quality of 39 lakes deemed worst by state pollution board
Panaji: The water quality of 39 lakes spread across Goa has been classified as Class E, which is the worst level and unfit for outdoor bathing. Most people in the state go to lakes for a summer dip. The lakes were tagged Class E mostly because the water in these water bodies is stagnant.
The Goa State Pollution Control Board (
GSPCB
) submitted the water quality data of the lakes to the
Central Pollution Control Board
(CPCB). The central authority periodically reviews water quality data of aquatic resources monitored under the National Water Quality Monitoring Programme (NWMP).
The water quality data of stagnant water bodies, including lakes, tanks, and ponds for the year 2023 was compared with primary water quality criteria for outdoor bathing.
'It is to inform that 39 locations are classified as Class E (irrigation, industrial cooling, controlled disposal) based on the designated best use of the water body, and some of the water bodies show a slight variation with respect to pH and conductivity,' the GSPCB said.

The water bodies are Ambulor lake, Bandolem lake, Batim lake, Betal temple lake, Bondvol lake, Canturlim lake, Carambolim lake, and Cottombi lake.
The others are Curca lake, Curtorim lake, Dashi lake, Dhakte (Diuler) lake, Dhulpe lake, Durga lake, Gawali-Maula lake, and Kamala lake.
The list also includes Karmale lake, Khandepar lake, Macasana lake, Maimollem lake, Malebhaat lake, Mayem lake, Nanda lake, Orlim lake, Panchami lake, Parra lake, and Pilerne/Saulem lake.
The other water bodies are Raitollem lake, Saipem lake, Sappu Tollem (Tollea Bandar), Sarzora lake, Sulabhat lake, Talaulim lake (Talsal lake), Tarvale lake, Tarvalem lake, Toyyar lake, Udden lake, Vodle Tollem, and Xeldem lake.
'Harvalem waterfall and Anjunem lake are classified as Class C based on the designated best use of the water body and are complying with the Class C parameters,' the GSPCB said.
A senior officer said, 'Water is classified as Class A to Class E, and Class A is the best quality of water, whereas Class E is the worst quality.' The officer added, 'It means that lakes classified as Class E are not fit for outdoor bathing but only for irrigation, industrial cooling, and controlled discharge.'
The Central Ground Water Board's annual groundwater quality report of 2024 said that Goa's groundwater remains among the safest for human consumption in the country on more than six parameters, with contents like fluoride, nitrate, and others in 100% of samples tested from the state.

'New lease on life': IVRI makes history with successful indigenous hip transplant for dogs in India; reduces cost to Rs 30K
BAREILLY: The scientists at the Indian Veterinary Research Institute (IVRI) achieved a milestone by successfully performing the first hip transplant surgery using indigenous technology in the country. This hip transplant is notable for being entirely developed with local technology. Until now, artificial hips for dogs were not available in India and had to be imported, costing at least Rs 5 lakhs. For nearly three years, IVRI scientists, Dr Rohit Kumar and his team, conducted a comprehensive study to develop not only a cemented hip suitable for Indian dogs but also the necessary instruments. Dr Kumar and his team took on this challenge, initially seeking insights from renowned human orthopaedic surgeon Dr Alok Singh. With technical assistance from Dr Singh and Bareilly Medicare Firm's Yogesh Saxena and Devesh Saxena, Life Ortho Care in Gujarat helped in developing the artificial hip and its instruments for dogs. Dr Rohit Kumar mentioned that the developed hip is quite affordable, allowing dog owners in the country to receive excellent treatment at a lower cost in the future. He told TOI, 'Earlier the cost of replacement surgery was very high as there was no implant manufacturer in India. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Keep Your Home Efficient with This Plug-In elecTrick - Save upto 80% on Power Bill Learn More Undo We all did a comprehensive indigenous study. Saw many surgeries in humans, developed all the dimensions on our own by taking multiple x-rays of the dogs. The cost of implant during the experimentation phase is between 25k-30k and even after commercialisation, the cost of hip replacement surgery would be very affordable. The best thing about it is that everything is developed and manufactured in India.' The technical design and dimensions were assigned to Dr T Sai Kumar for MVSc research and Dr Kamlesh Kumar for PhD research. This work was carried out under the AINP-DIMSCA (All India Network Programme on Diagnostic Imaging for Surgical Conditions in Animals) project by the team of Dr Rohit Kumar, Dr Amarpal, Dr A C Saxena, and Dr AM Pawde. Dr Amarpal said, 'This is the first time such a study was systematically conducted in the country, with the first surgery performed in Dehradun, the second in Bareilly, and the third on a police dog in Sambhal, giving them a new lease on life." On this achievement, IVRI's Director Dr Triveni Dutt lauded the collective efforts of the entire team and encouraged making this technology available to dog owners nationwide and transferring it to the industry as soon as possible.

Karnataka rivers choke as water quality dips to dangerous levels
Class D river stations National Water Quality Monitoring Programme Karnataka State Pollution Control Board Rivers in Karnataka, which are being monitored under the(NWMP), are deteriorating at an alarming number of river monitoring stations reporting poor water quality has doubled over the last five years, raising serious environmental concerns across the state. According to the(KSPCB), in 2019-20, 10 river stations were classified under the Class D category. That figure has now risen to the number of stations with water quality under Class C has dropped from 77 to 59—pointing to a steady decline in overall river officials attribute the degradation primarily to the unchecked discharge of untreated sewage from surrounding towns, cities, and villages into rivers. The majority of river stretches in Karnataka now fall under the Class C category, which means the water is fit for domestic use after physical and chemical treatment followed by the NWMP, KSPCB monitors seven major river systems in the state—Krishna, Cauvery, Godavari, North Pennar, South Pennar, Palar, and the West Flowing Rivers. The Board collects water samples from 325 monitoring stations, including 100 river stations, 196 lakes or tanks, two bore wells, and five coastal and marine areas. Unlike stagnant water bodies such as lakes and ponds, rivers possess a natural self-purification process, making them easier to rejuvenate using nature-based interventions. However, the growing number of river stations under Class D highlights a lack of effective on-ground pollution control measures.'If the discharge of untreated sewage and industrial waste is halted, river water quality can improve significantly within a short period,' said a city-based hydrologist. 'The increase in Class D stations clearly shows that this essential step is still not being implemented effectively.'Currently, KSPCB permits the discharge of treated industrial effluents into rivers at just three locations across the state Bhadra River near Bhadravathi in Shivamogga, Tungabhadra River near Harihar in Haveri, and Kali River near Bangur Nagar in Dandeli.

Won't apologise for standing up for patient denied care: Goa Health Minister Vishwajit Rane
Panaji, Goa Health Minister Vishwajit Rane has defended his decision to order suspension of a doctor from a state-run hospital, citing the latter's "arrogant behaviour" towards a patient. The minister on Saturday said he will not apologise for standing up for a patient who was denied care. Rane said he took the action after receiving a complaint from a senior journalist who pointed out that his mother-in-law was mistreated by the doctor in the casualty ward of the Goa Medical College and Hospital .

It provides medical services to patients from Goa as well as from nearby areas of Maharashtra and Karnataka. Its Chief Medical Officer Dr Rudresh Kurtikar was fired in public view and later ordered to be suspended by Rane after he "lost his cool" during his surprise visit to the GMCH on Saturday. Live Events Later, talking to reporters on Saturday evening, Rane said "Yes, as the health minister, I did intervene and I accept that my tone and words could have been more measured. I am not above reflection or criticism. I take full responsibility for how I communicated, and I assure you such an approach will not be repeated." "However, what I will not apologise for is standing up for a patient who was denied care," the minister said. Doctors hold a noble position in the society, and most of them at the GMCH serve with great dedication, he noted. "But when arrogance seeps into duty, when compassion is replaced with indifference, it is my responsibility to take action," Rane said. The minister was reacting to criticism he faced on social media and also by the Indian Medical Association against his act of firing the CMO on duty. "Over the last few hours, a lot has been said and written about an incident at the Goa Medical College today and the suspension of a doctor on duty. I feel it is important to address this directly, not just as your health minister, but as someone deeply committed to ensuring that no citizen is ever denied basic medical care, especially the elderly who deserve our utmost respect and attention," he said. Rane said he had received a message from a family member of a senior citizen, who was already in pain and advised to receive daily injections, about how she was refused the same at the medical college's casualty ward on a public holiday. "What made the matter worse was that the casualty (ward) had minimal patient load at the time, and yet, a simple act of compassion and care was withheld. I found this deeply upsetting," he said. Rane said often the outrage is highlighted on same media platforms and by the public when things go wrong at the GMCH. But when corrective action is taken, it is equally important that "we support efforts to fix the system, not tear them down," he commented. The minister said what he did was in defence of a helpless, elderly woman. "And I will continue to speak up, act and fight for the rights of every patient who walks into our hospital," he asserted.
