493 Preparing for AWT 2026: Leadership, Change, and CWT Growth with Matt Coffindaffer, Part 1
Scaling UP! H2O
Strong professional associations do more than provide programs and credentials. They create an environment where members can exchange knowledge, build trusted relationships, and prepare their businesses for what comes next. As the Association of Water Technologies enters a new operational chapter, Executive Director explains how AWT is strengthening that environment without losing the culture that makes it distinctive. From the Arts to Association Leadership Before entering association management, Matt built a career behind the scenes in theater. His...

491 Environmental Microbiology and Legionella: Managing Building Water Risks with Dr. Rajiv Sahay
Scaling UP! H2O
Reliable Legionella results begin long before a sample reaches the laboratory. of explains how building conditions, field collection practices, and laboratory methods influence the quality—and usefulness—of the data water professionals receive. Building Water Conditions Shape the Risk Modern buildings rely heavily on controlled mechanical systems, yet water can remain an overlooked part of the indoor environment. Stagnation, low flow, dead legs, temperature, pH, disinfectant residuals, corrosion, and accumulated organic material can all influence biofilm development and microbial...

490 From Plans to Prevention: Water Management Insights with Dr. Abe Cullom
Scaling UP! H2O
A water management plan protects people only when the facility uses it to guide decisions. Dr. Abe Cullom, Director of Water Safety & Management at Pace Analytical, joins Trace Blackmore, CWT, to examine why Legionella programs break down—and how testing, communication, and consistent implementation can strengthen them. Implementation Is the Bottleneck Five decades after Legionella was identified, researchers understand much more about the organism, its ecology, the conditions that support its growth, and the interventions available to control it. However, Dr....

489 Copper-Silver Ionization Technology and Legionella Control with Tory Schira
Scaling UP! H2O
Copper-silver ionization offers building operators a persistent approach to Legionella control—one designed to carry an active disinfectant residual throughout complex plumbing infrastructure. LiquiTech CEO Tory Schira explains how the technology works, what operating data matters, and why successful implementation requires more than installing equipment. How Copper-Silver Ionization Works Copper and silver ions are introduced through a flow chamber containing sacrificial electrodes. A controlled electrical charge releases the positively...

488 Managing Legionella with confidence: A Conversation with Patsy Root
Scaling UP! H2O
“Our goal is not zero Legionella pneumophila bacteria. Our goal is zero cases.” – Patsy Root Legionella risk becomes harder to manage when building teams treat every detection as equivalent—or collect samples without first deciding what a positive result will trigger. , Senior Manager of Government Affairs at , explains how a clear water management program can replace uncertainty with defined responsibilities, routine monitoring, and proportionate action. Focus Testing on the Organism of Concern Patsy distinguishes between the broader...

486 Meter Optimization: Air in the water with Anthony Giudice
Scaling UP! H2O
Water meters register the volume passing through them, but what happens when that volume contains both water and entrained air? Anthony Giudice, president of AquaFlow, explains how turbulent flow can influence meter readings and how AquaFlow’s calibrated valve is designed to help meters reflect what he describes as true water consumption. Why Flow Conditions Matter at the Meter Anthony connects entrained air to the pressure required to move municipal water and the turbulence created as water travels through piping, changes...

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,...
info_outlineBiofilm is not a fringe issue in cooling systems. As Dr. Jeff Kramer explains, it is a given. That matters because biofilm affects heat transfer, contributes to corrosion, and can serve as a reservoir for Legionella in treated systems. In this conversation, Trace Blackmore and Dr. Kramer examine what experienced water treaters should be looking for when choosing and evaluating a microbiological control program.
Biofilm as an operating problem
Dr. Jeff defines biofilm as a community of microorganisms attached to a surface and held together by an external polymeric matrix. From there, the discussion moves quickly into why these matter in the field. He points to research showing that biofilms can be more insulating than mineral scale, then explains how microbial activity and patchy film formation can intensify corrosion risk. He also notes that Legionella can be harbored within biofilm, making clean-looking bulk water an incomplete picture of system condition.
Choosing the right biocide program
A strong oxidizing biocide foundation remains central, whether based on chlorine or bromine. However, Dr. Jeff makes a practical distinction that matters to service professionals: some non-oxidizing biocides kill biofilm organisms without removing the film, while others both kill and remove. He also explains why shock dosing often outperforms smaller, more frequent additions, and why biocide timing should be evaluated in the context of oxidizer compatibility, halogen demand, and actual system feedback rather than habit or opinion.
Surfactants, TTPC, and field realities
The conversation also covers how surfactants and quaternary compounds can disrupt microbial membranes and improve biocide penetration. Dr. Jeff shares lab and field insight on TTPC, including its strong performance in kill-and-removal testing and its known interference with PTSA fluorescence programs. The discussion closes with practical monitoring advice: inspect the basin, feel below the waterline, trend dip slides, watch approach temperatures, and pay attention to residence time when selecting products for different system volumes and turnover rates.
Better microbiological control is not about one product or one rule of thumb. It is about understanding the system, interpreting feedback, and matching chemistry to operating reality so performance can be maintained over time.
