Release Date: 01/30/2026
485 Questions from the Nation Around the World with Trace Blackmore, CWT
Scaling UP! H2O
Ten questions from water professionals around the world become a practical decision-making session with Trace Blackmore, CWT. Drawing on earlier Scaling UP! H2O conversations, Trace explains how to evaluate treatment changes, use emerging tools responsibly, begin water reuse projects, strengthen teams, and continue growing professionally. Evaluate the Entire System A proposed treatment change should be evaluated by more than its purchase price. When comparing chlorine dioxide with traditional chlorine, Trace recommends examining biocide consumption, chemical storage,...

484 Risk, Resilience, and Water Security with Dr. Newsha Ajami
Scaling UP! H2O
Industrial operations depend on water of a predictable quantity and quality, yet many organizations still treat that reliability as a given. joins Trace Blackmore, CWT, to examine water security as a business continuity issue and resilience as the ability to withstand pressure, maintain operations, and recover quickly when systems fail. Connecting Risk, Resilience, and Recovery For industrial water users, water security means maintaining access to the quantity and quality required to operate without interruption. That reliability depends on...

482 Preserving Our Industry’s Story – Paul Petersen and the Industrial Water Exhibit
Scaling UP! H2O
Industrial water treatment has always supported industry, but much of that story remains invisible to the public. Paul Petersen wants to change that by helping establish an industrial water treatment presence at the National Museum of Industrial History in Bethlehem, Pennsylvania. Paul Petersen, former president and CEO of Trident Technologies and current leader of the Industrial Water Task Group, joins Trace Blackmore to explain why preserving the industry’s history matters. His vision is not simply a static display of old equipment. Instead, the goal is to...

481 From Waterfalls to SOPs: Building Better Utilities with Kalpna Solanki
Scaling UP! H2O
Water utility work depends on more than technical knowledge. It depends on clear procedures, current documents, practical training, and performance conversations that reflect what operators actually do in the field. In Episode 481, Trace Blackmore, CWT, welcomes back , President and CEO at , for a practical conversation on building stronger utilities through standard operating procedures, competencies, and performance evaluations. Kalpna shares how outdated SOPs, disconnected training tools, and top-down documentation can create risk, confusion, and missed...

480 From Engineering Numbers to People, Power, and Policy with Sherine El‑Wattar
Scaling UP! H2O
Industrial water professionals work with chemistry, equipment, permits, and performance targets every day. Yet every gallon also moves through a framework of policy decisions: who can withdraw water, how it may be used, what quality must be returned, and whose needs are considered when systems are designed. , a science network officer supporting the Working Group II Technical Support Unit, brings an engineering foundation and a human-centered perspective to those questions. Her work focuses on climate impacts, adaptation, vulnerability, and risk while helping...

479 Water Treatment: The Next Generation - Hustle Culture Meets Emotional Literacy with Tiffany Wentz‑Root
Scaling UP! H2O
In today’s episode of Scaling UP! H2O, host Trace Blackmore sits down with workplace resilience expert and U.S. Marine veteran to decode how different generations show up in the industrial water treatment industry. From the Silent Generation’s post‑war loyalties through Baby Boomers’ commitment to long hours, Gen X’s distrust of corporate loyalty, Millennials’ desire for purpose and feedback, and Gen Z’s demand for emotional literacy, the conversation illustrates how each cohort was shaped by historical and technological upheaval. The discussion reframes “hustle...

478 Rethinking Power Plant Water and Steam Chemistry with Brad Buecker (Part 2)
Scaling UP! H2O
Power plant water and steam chemistry does not fail in isolation. A mistaken unit, an unused analyzer, an overdesigned pretreatment system, or a misunderstood condensate return problem can ripple across equipment, permits, production, and safety. In this Part 2 conversation with of and Buecker Associates, Trace Blackmore continues a practical discussion on the details that shape industrial water decisions. Brad shares field stories from combined cycle plants, package boilers, wastewater permitting, membrane systems, and decades of technical writing. When Small Errors Become Expensive...

477 Rethinking Power Plant Water and Steam Chemistry with Brad Buecker (Part 1)
Scaling UP! H2O
Power plant water and steam chemistry is not a background task. It affects safety, reliability, metallurgy, production, and the decisions plant teams make under pressure. In Part 1 of this conversation, Trace Blackmore, CWT, welcomes Bradley Buecker of SAMCO Technologies and Buecker Associates to examine what happens when familiar assumptions go unchallenged. Safety Comes First in High-Energy Systems Bradley begins with the lesson that has shaped decades of his work: safety. Power and industrial systems involve heat, flow, moving equipment, chemicals, confined spaces, lockout/tagout...

476 Positive Communication, Temperaments, and the WOW Effect with Paule Genest
Scaling UP! H2O
Communication shapes how teams learn, respond, correct, and build trust. Trace Blackmore, CWT welcomes returning guest Director, Sales and ESG (Environment, Social and Governance) Water and Energy TGWT / The Tannin Guys for a conversation on positive communication, temperaments, the WOW Effect, and how water professionals can use words with more clarity and care. Communication With a Positive Impact Paule reframes positive communication as communication with a positive impact. The goal is not fake positivity or polished language....
info_outlineCorrosion rarely announces itself as a “big water problem.” It shows up as leaching at the tap, residual loss in the field, premature equipment replacement, and the slow, expensive erosion of decision-quality.
Pat Rosenstiel (CEO) and Wolf Merker (chemist/Chief Science Officer) of Great Water Tech lay out a system-wide view of corrosion control—starting with what changed in Flint from a technical standpoint and moving into why many utilities still struggle to meet expectations when standards and risk assumptions shift.
System-wide corrosion control starts with chemistry and consequences
A source-water change can shift corrosivity fast. If corrosion control does not adjust proactively, the downstream effects show in metal release and public exposure. Wolf stresses the distinction between the technical problem and the political challenges, then points to corrosion control as a solvable technical matter when it is treated as a system condition—not a single asset issue.
Why “phosphate-only” isn’t the end of the story
Trace frames what most operators recognize: many municipalities use phosphate inhibitors to form a tenacious film and reduce corrosion. Wolf argues phosphates are “a little bit of old news” in practice and explains the approach Great Water Tech discusses with their German partners—using phosphates and silicates together in the right amounts to create a tighter separation between water and metal.
Barriers, biology, and the disinfection tradeoff
Wolf breaks corrosion drivers into three sources: chemical, biological, and electrochemical (dissimilar metal corrosion). He also ties corrosion to cascading operational decisions—especially disinfectant strategy. If residual loss pushes a system from chlorine to chloramine, Wolf warns that corrosivity can increase dramatically, and that corrosion can amplify the formation of disinfection byproducts as chlorine reacts with what is in the water.
What industrial water treaters should listen for
Pat connects the same barrier logic to industrial priorities—CapEx, OpEx, and lifecycle extension in closed systems (cooling towers, closed chilled loops, boilers). Wolf clarifies that closed systems require different product “flavors,” while keeping the core concept consistent: the combined silicate/phosphate approach remains the best path he is aware of.
