Podcasts about Deoxygenation

What if preventing Legionella outbreaks wasn't about adding more chemicals, but removing what the bacteria needs to survive? In this episode of Scaling UP! H2O, host Trace Blackmore talks with Dr. David Krause, Certified Industrial Hygienist, toxicologist, and founder of HC3, about his groundbreaking approach — LIDO (Legionella Inhibition by Deoxygenation). Legionella on the Rise  Dr. Krause has investigated high-profile Legionella outbreaks and seen firsthand how current prevention strategies often fall short. Despite ASHRAE 188 standards, CMS requirements, and increasing water management plan adoption, Legionella cases continue to climb — often due to infrastructure issues, insufficient monitoring, and a lack of evidence-based guidance.  Inside an Outbreak Investigation  From the first call at 4:30 on a Friday to the coordination between local health departments, state agencies, and the CDC, Krause explains the rigorous (and sometimes chaotic) process of pinpointing outbreak sources. He also reveals why public communication can make or break an outbreak response.  Introducing LIDO Technology  Rather than relying solely on chemical disinfection, LIDO uses gas transfer membrane contactors to remove dissolved oxygen from hot water systems. Legionella can't thrive below 0.3 ppm DO — meaning systems treated with LIDO create an inhospitable environment for growth. Krause shares lab results, pilot project findings, and how this approach could extend system life while reducing corrosion and byproducts. The Bigger Picture  This episode goes beyond technology — it's about rethinking water management, building better outbreak communication, and challenging industry norms. Whether you're a facility manager, water treater, or public health professional, Krause's insights will shift the way you think about Legionella control.   Prevention starts with awareness — and action. Dr. Krause's work shows there's more than one path to safer water systems, and innovation comes from asking better questions.  Listen now to discover how Legionella investigations unfold and how LIDO technology could reshape prevention.

Dr. Julia Huggins Part 2In this episode, we welcome back Dr. Julia Huggins to dive into the world of ocean microbes and their critical role in our planet's health. Dr. Huggins shares her research on how ocean warming, acidification, and deoxygenation are impacting these essential microorganisms. She explains that maintaining healthy ocean circulation is crucial for balancing microbes, nutrients, and energy, which in turn affects global weather patterns and climate stability.Dr. Huggins delves into the consequences of disrupted oceanic conditions, highlighting how changes in temperature, pH levels, and oxygen availability can lead to significant shifts in microbial populations. These shifts can have cascading effects on marine ecosystems, from the smallest plankton to the largest marine mammals. By understanding these connections, we can better appreciate the importance of preserving ocean health in the face of climate change.Additionally, Dr. Huggins emphasizes the need for robust scientific research and global cooperation to mitigate these issues. She discusses potential strategies for protecting ocean circulation and maintaining microbial balance, ensuring a sustainable future for our oceans and, by extension, our planet. This episode offers valuable insights into the intricate web of life beneath the waves and underscores the urgent need to address environmental challenges affecting our seas.Please rate, review and share this episode and this podcast with your friends and colleagues.

According to a new study, approximately 70% of the world's oceans could be suffocating from a lack of oxygen by 2080 as a consequence of climate change.  This has the potential to impact marine ecosystems all around the world.   The study, which was recently published in the journal Geophysical Research Letters, is the first to […]

In this episode of Changing Waters, Global Ocean Health's Julia Sanders interviews Dr. Lisa Levin. From Scripps Institute of Oceanography, Dr. Levin studies deep sea and coastal deoxygenation, including taking deep sea videos of oxygen minimum zones. She discusses her work, as well as a recent op-ed she co-wrote in The Ecologist, which talks about tackling climate change via the United Nations/Paris Agreement. Julia and Dr. Levin also share their experiences at COP21, where the Paris Agreement was signed.

Episode 98 - "Water World (Spoiler: Not So Good)" The latest IPCC report details observed effects of climate change on the ocean and cryosphere (really really cold places), which are altering the environment from the highest mountain peaks to the lowest depths of the ocean. The implications for our world are significant. The ocean, which has been absorbing 90% of the excess heat we produce, is giving way to critical levels of acidity and hypoxia threatening the foundation of all marine life. Sea level rise caused by melting ice and thermal expansion threatens to transform once-in-a-century sea level events into regularly occurring annual events by 2050. As if that were not enough, arctic sea ice is decreasing, marine heatwaves are accelerating, permafrost is melting, and planet-scale ocean currents are slowing. If you want to learn more, you've come to the wrong place. You'll find nothing here but rants and nonsensical metaphors.

Seven and a half billion humans are changing the way we relate to the oceans. In this fast-changing world, marine animals and plants must adapt fast to a warmer and corrosive environment as ocean acidification, pollution and deoxygenation continue. This global crisis is causing humans to be anxious about the safety of our oceans for recreation and as a source of food. Debora Iglesias-Rodriguez discusses how humans can contribute to ameliorate current ocean problems and eventually return the oceans to a more sustainable state.
