    Navigating Microplastics in Drinking Water: The Challenges of Potential Regulations

    In this episode Talking Under Water co-host Mandy Crispin speaks with Brent Alspach, Vice President and Director of Applied Research at Arcadis, about the evolving science of microplastics in drinking water and the challenges facing future regulation. Recorded at ACE26, the conversation explores what has changed over the past year in the industry's understanding of microplastics and why policymakers, utilities, and researchers are still searching for answers. Brent explains why defining microplastics for regulatory purposes is far more complex than defining traditional contaminants, given the wide range of particle sizes, polymer types, and characteristics involved. He also discusses concerns that public and political pressure could outpace the scientific research needed to support effective regulations. The discussion covers the many hurdles that remain before any federal drinking water standard could be developed, including the lack of standardized sampling methods, testing protocols, and health effects data. Mandy and Brent also examine how regulators might determine whether drinking water is a significant source of human exposure compared to food or air. Finally, Brent shares insights into how existing treatment processes perform, where knowledge gaps still exist, and what utility leaders should be doing today to prepare for a future in which microplastics receive greater regulatory attention.

    Revolutionizing Water Management: The Circular Water Economy

    In this episode Talking Under Water co-host Bob Crossen speaks with Krishna Prashanth, global product line manager for electromagnetic flow meters and global segment manager for water and wastewater instrumentation at ABB, about the promise and practicality of the circular water economy. Prashanth explains how the concept shifts water management away from a linear take-treat-discharge model and toward a system focused on reducing losses, reusing water, recovering resources and extending the value of every drop. He outlines the “six Rs” — reduce, reuse, recycle, reclaim, recover and restore — and argues that utilities must evolve from operators of pipes and plants into stewards of local water loops. The conversation also explores the critical role of data capture, monitoring and analysis in making circularity possible, from identifying leaks and managing demand to improving reuse decisions and predicting infrastructure issues. Prashanth and Crossen discuss how AI can strengthen these efforts when paired with trusted instrumentation, as well as the barriers standing in the way, including regulatory silos, misaligned incentives and aging infrastructure. Together, they paint a picture of a more resilient, efficient and resource-aware future for water utilities.
