Talking Under Water episodes
- EPA’s legal PFAS battle, tariff fallout, and America’s aging water systemsIn this episode, Talking Under Water co‑hosts discuss the newest PFAS regulatory developments, major legal challenges, and the mounting strain on water and stormwater infrastructure across the U.S. The conversation begins with the EPA’s decision to add PFHXSNA to the Toxics Release Inventory, expanding federal PFAS tracking and community access to chemical data. The hosts then outline the unfolding court battle over EPA’s PFAS drinking water rule, detailing the agency’s motion to sever and pause litigation on the hazard index and the strong opposition filed by AWWA and AMWA, who argue that utilities need unified judicial review to plan for compliance.The episode also explores the Supreme Court’s recent ruling striking down President Trump’s tariff plan and how the administration is seeking new legal pathways to maintain tariffs. From there, the hosts examine the politically charged response to the Potomac Interceptor sewer collapse, highlighting the operational, financial, and communication challenges surrounding the incident.Closing out, the show turns to stormwater struggles on both coasts — catch basin failures and compliance gaps in Connecticut, and severe flooding, lawsuits, and multibillion‑dollar funding shortfalls in San Diego — underscoring nationwide infrastructure vulnerabilities. The episode concludes with key industry updates and program announcements.Show Notes

28 min - Building the next generation of water utility leaders: inside Xavier University’s new master’s program
In this episode Talking Under Water co-host Bob Crossen talks with John Ikeda and Justin Roush about the launch of Xavier University’s groundbreaking Water Utilities Management master’s degree — the first program of its kind in the United States. Together, they discuss how the degree was conceived, the industry challenges it aims to address, and why workforce development has become one of the most urgent priorities for water and wastewater utilities.
Ikeda, chief mission officer at the Water Environment Federation (WEF), and Roush, assistant economics professor at Xavier and director of the new program, outline the growing need for specialized utility leadership as retirements accelerate and system complexity increases. They explain how the curriculum blends foundational business skills with utility‑specific coursework in areas like rate setting, regulation, capital improvement planning, and strategic communications. The discussion also highlights unique residency experiences, cohort‑based learning, and the program’s intentional focus on networking and long‑term career growth.
Crossen, Ikeda, and Roush explore how the master’s degree fits into broader sector‑wide workforce strategies and why emerging topics — such as AI in water — are being built directly into the curriculum. The episode offers a forward‑looking look at how the program aims to elevate future water utility leaders across the U.S.

32 min - Forecasting water in 2026: data centers and wastewater association goals
In this episode of Talking Underwater, co-hosts Mandy Crispin and Bob Crossen explore the forces shaping the water and wastewater sector as the industry looks ahead to 2026.
The conversation opens with insights into new research on the growing water demands of data centers in Texas. Drawing from a recent white paper by the Houston Advanced Research Center (HARC), Crispin outlines how existing and planned data center development could significantly strain drinking water supplies if water planning and policy fail to keep pace with rapid growth.
Crossen then shares insights from a January poll on wastewater capital spending priorities. Results show utilities are primarily focused on treatment process upgrades and collection system improvements, while resilience and emergency preparedness rank surprisingly low.
The episode wraps with a broader look at 2026 industry forecasts from the Water Environment Federation (WEF) and the National Association of Clean Water Agencies (NACWA). Key themes include workforce development, the rise of the circular water economy, policy efforts around PFAS and the “polluter pays” principle, funding through state revolving funds, and affordability programs such as LIHWAP. Together, these perspectives suggest a shift from big‑picture concepts toward practical action as utilities confront emerging challenges and opportunities in the year ahead.

16 min - One Water: AI and energy needs in a sustainable water future
In this episode Talking Under Water co-host Bob Crossen speaks with Gabriel Collins, the Baker Botts Fellow in Energy and Environmental Regulatory Affairs at Rice University’s Baker Institute for Public Policy, about the evolving pressures on industrial water use and the widening implications of the AI boom. Drawing from his cross-sector expertise, Collins unpacks why water is an inherently hyper‑local resource and how industries — ranging from semiconductor fabrication to refineries and petrochemical plants — are adapting to shrinking supplies and rising costs.
The conversation explores how data centers are straining municipal systems and, in some cases, driving new water‑reuse investments. Collins shares real‑world examples illustrating how creative contracting and industrial partnerships can help utilities upgrade critical infrastructure. He also highlights the increasing viability of air‑cooling technology as an alternative in water‑scarce regions.
Shifting to oil and gas, Collins explains how produced water, seismicity concerns, and disposal challenges are prompting operators to rethink water management strategies. Throughout the discussion, he stresses the importance of “fit‑for‑purpose” water use and the opportunities for circular water practices that avoid mixing contaminated and freshwater streams.
The episode closes with a look at the logistical and economic barriers that still limit a truly integrated one‑water approach.

14 min - The Cost of Quality: Rethinking Water Meter ROI
The water meter is the cash register for a water utility. For those how have worked win the water business for any amount of time, they've likely heard that adage. But how does a water system choose the right meter for the utility? Should utilities pick the cheap option because they cash-strapped? What is the difference if they are willing to pay for higher quality?
In this sponsored interview with Kamstrup, Jake Piccioni, solution manager for Kamstrup, talks about the company’s “culture of quality” to ensure their customers have the very best meters in their systems. Learn how high quality meters can lead to long-term savings with total cost of ownership, and that’s even before considering the benefits that newer modern meters offer utilities in terms of accuracy, pressure and other measured parameters.

- 08:00 – Given this scrutiny Kamstrup places on the design and materials, how then does that cultural of quality translate to manufacturing of the meters? What rigors do these meters go through for QA and QC?
- 10:54 – What are the dangers of having poor or inaccurate data for a utility? What can utilities realize when they have good data?
