Drinking Water Contaminant Removal podcasts

  1. Microbial Contamination Monitoring For Water Distribution Systems
    7/5/2017

    Back in 2014, Louisiana’s Department of Health and Hospitals wrote an executive order for municipalities to boost their chlorine residuals as high as possible to burn off all biofilm and stop the outbreak of brain-eating amoeba (Naegleria fowleri) that had been detected as the cause of death in a number of individuals.

  2. Treatment Alternatives For PFCs
    7/4/2017

    Over the past two years, no groundwater issue has perhaps received as much community focus and attention as polyfluoroalkyl and perfluoroalkyl substances like PFOA and PFOS, often referred to as perflourinated compounds (PFCs). The U.S. EPA issued a health advisory, limiting the amount of these compounds to 70 parts/trillion which kicked off a nationwide evaluation of local water sources.

  3. Lighting The Way: Next Steps For UV Disinfection (Audio)
    6/23/2015

    With more than 8,500 municipal installations over 40 years, TrojanUV is well-versed in UV disinfection. What’s next for the technology? Adam Festger, TrojanUV’s market manager for drinking water and environmental contaminant treatment, reveals new trends and products to Water Online Radio’s Todd and Kelly.

  4. Fighting India’s Arsenic Problem
    10/15/2015

    When Vinny Gupta, the president and CEO of InNow LLC, met Rich Cavagnaro, the CEO of AdEdge Water Technologies, he saw an opportunity to help 40 million people get clean water.

  5. Coconut Shell Activated Carbon For Removing PFOA And PFOS
    7/8/2016

    Coconut shell activated carbon is typically used for filtration in cleaner waters. Its alternatives are coal-based or wood-based carbon. With the recently published EPA guidelines on perfluorinated compounds, Water Online Radio sat down with Neal Megonnell, Senior Vice President for Haycarb USA, to understand coconut shell activated carbon’s application in fighting PFOA and PFOS.

  6. Biological Filtration For Drinking Water Treatment Takes Off
    7/11/2016

    Biottta is a relatively new biological filtration process for drinking water treatment, addressing nitrates, perchlorates, chromium-6 and a number of VOCs as well. In this Water Online Radio interview, AdEdge Water Technologies’ Chad Miller and Rich Cavagnaro discuss its emergence in the water treatment market and some of the specific contaminants it addresses.

  7. The Reward Of Risk: New Tech Pays Off
    8/20/2014

    The engineering community can sometimes be wary of trying anything other than the technologies they are already accustomed to, says Rich Cavagnaro of Adedge, a purification technology company with a focus on nitrates and radionuclides.

  8. On Site Hydrogen Peroxide Generation for Advanced Oxidation Process
    7/6/2016

    Vitamins, steroids and hormones are all emerging as contaminants being detected in drinking water supplies. As Jon McClean, Chief Technology Officer with Neptune Benson explains in this Water Online Radio interview, advanced oxidation processes (AOPs) add hydrogen peroxide in front of UV treatment to eradicate contamination.

  9. Making Sense Of PFOA And PFOS
    6/27/2018

    In addition to the bewildering alphabet soup of acronyms associated with perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), together known as per- and polyfluoroalkyl substances (PFAS) or perfluorinated compounds (PFCs), there is confusion as to how dangerous and prevalent these chemicals are, and thus how they should be treated or regulated. To help bring clarity to the issue, Pete D’Adamo, Director of Water Treatment for HDR, spoke on Water Talk with Water Online's Todd Schnick and Kevin Westerling. D'Adamo discusses the background and scope of the issue, as well as treatment methods and what to expect next. Tune in below to hear the conversation.

  10. A Sustainable Solution For Treating Contaminants
    11/13/2014

    There are a number of regulations in drinking water centered around emerging contaminants. Hexavalent chromium is one that you’ll see on the national marketplace.
