51. Ozone And PFAS: The Overlooked Tool In A National Water Crisis 9/25/2025

    Ozone is a vital pre-treatment for PFAS mitigation. It oxidizes precursors and co-contaminants, significantly extending the service life of downstream GAC and membrane systems.

52. Nanobubble Ozone Technology – Advancing Mass Transfer Through Physics 9/25/2025

    Nanobubble physics enable higher ozone stability and mass transfer efficiency in water. Discover how the negative surface charge of these microstructures improves localized oxidation and penetration into difficult matrices.

53. New PFAS Timeline Delays Military Site Cleanup By Up To A Decade 9/25/2025

    The Department of Defense has postponed PFAS cleanup at nearly 140 U.S. military installations, with little public notice. According to a list analyzed by The New York Times, the new timetable delays some site cleanups by nearly a decade. 

54. The Hidden Cost: Uncovering The Truth About Non-Revenue Water 9/25/2025

    Non-revenue water drains utility budgets, resources, and public trust. Audits, ultrasonic metering with acoustic leak detection, and community engagement provide practical, cost-effective steps to curb losses and improve efficiency.

55. De-Risking Chemical Contamination In Non-Potable Reuse Water Applications 9/24/2025

    Discover how German scientists piloted edible crop irrigation with reuse water at a German water reclamation facility to create a comprehensive chemical risk assessment framework, progressing reuse’s feasibility in Europe.

56. The Water Online Show: Bridging The Digital Gap In Water Utilities With AI Solutions 9/24/2025

    On this episode of The Water Online Show, Travis Kennedy spotlights LeakZon’s breakthrough hybrid solution that bridges the gap between traditional AMR and full AMI systems. CMO Tomer Eisner explains how the technology seamlessly integrates with existing infrastructure, enabling utilities to capture AMI-like insights without costly overhauls.

57. EPA To Roll Back Coal-Fired Power Plant Wastewater Rules 9/23/2025

    As part of the recent administration’s efforts to loosen environmental rules for fossil fuels, the U.S. EPA signaled its intention to delay the compliance deadline for effluent limitations targeting coal-fired power plants. The agency did so in July 2025 in a filing with the U.S. Court of Appeals for Eighth Circuit in St. Louis, Missouri.

58. Extracting Water From Air: A Historical And Military Perspective 9/23/2025

    In the early 2000s, I was consulting for a military contractor on expanding their mobile water treatment system for military applications. As part of that work, I researched other water supply technologies used by the U.S. military, including atmospheric water generation (AWG) — the process of extracting potable water directly from the air.

59. Solving The World's Microplastics Problem: 4 Solutions Cities And States Are Trying After Global Treaty Talks Collapsed 9/23/2025

    Microplastics seem to be everywhere — in the air we breathe, the water we drink, the food we eat. Countries have tried for the past few years to write a global plastics treaty that might reduce human exposure, but the latest negotiations collapsed in August 2025. While U.S. and global solutions seem far off, policies to limit harm from microplastics are gaining traction at the state and local levels.

60. Digital Solutions For City Water Challenges: A New Blueprint For Sustainable Cities 9/22/2025
    Cities are grappling with a combination of threats that make urban water management a defining challenge of the 21st century. In this context, digital transformation is emerging as a critical enabler, reimagining how urban water systems confront these realities and prepare for the uncertainties ahead.
