CONTAMINANT REMOVAL RESOURCES

• Pretreatment Systems Enable Complete And More Economical PFAS Solutions

  For operators looking to optimize their PFAS removal systems, controlling the presence of dissolved organic carbon (DOC) offers an approach to minimizing operational costs due to granular activated carbon (GAC) reactivation and ion exchange media change-out.

• What Utilities Don't Know About GAC Reuse For PFAS

  For utilities building PFAS treatment systems, thermal reactivation of spent granular activated carbon (GAC) may sound like the obvious answer. However, service provider availability and location, specific media acceptance criteria including quantity thresholds, restrictions on GAC type and condition, and regulatory uncertainty can all determine whether reuse is a viable option.
• Microbial And Disinfection Byproducts Regulations: Paving The Way For Efficient Compliance

  Given the ongoing regulatory activity in the water industry, it’s hard to imagine another major drinking water rule on the horizon. But the U.S. EPA is planning revisions to the microbial and disinfection byproducts (MDBP) regulations.
• Transparent Exopolymer Particles (TEP): The Invisible Driver Of Biofouling In Water Systems

  A growing body of scientific evidence points to transparent exopolymer particles (TEP) as one of the most important, but frequently overlooked, drivers of biofouling in water systems. Understanding TEP may provide a new perspective on why biofilms develop so rapidly, why some treatment systems foul despite acceptable microbial counts, and why conventional control strategies often struggle to deliver lasting results.
• The Pros And Cons Of Pilot Testing For PFAS Removal

  Deploying uncustomized equipment for contaminant testing can skew critical operational data. Discover how precisely tailored small-scale testing isolates site-specific variables, protects long-term maintenance budgets, and ensures seamless regulatory compliance for full-scale water treatment facilities.

• Protecting The World's Most Essential Resource: How Utilities Can Navigate Growing Risks To Drinking Water Supply

  Protecting drinking water supply has become more complex, more urgent, and less predictable as utilities navigate a convergence of pressures, including climate variability, emerging contaminants, and accelerating population growth. Together, these trends are redefining what it means to deliver safe, reliable drinking water. Yet within this disruption lies a critical opportunity.
• Municipal Water Treatment: A Look At The Advantages Of Performance Testing For Powdered Activated Carbon

  Evaluating Powdered Activated Carbon through site-specific performance testing allows water utilities to optimize chemical dosing based on real-world efficacy rather than upfront price, preventing costly operational strains and ensuring reliable contaminant removal.

• How The City Of Fallon Improved Sodium Hydroxide Dosing Reliability

  Learn how transitioning to peristaltic metering technology solved chronic priming and maintenance issues during arsenic removal. This overview highlights how specialized pump designs improve chemical dosing reliability, enhance operator safety, and maximize facility space.

• Designing Resilient PFAS Treatment Strategies For Water Agencies

  Water agencies across the U.S. are facing a rapidly evolving regulatory landscape for per- and polyfluoroalkyl substances (PFAS) that poses a conundrum: Should they take a cautious or aggressive approach to treating PFAS contamination in their water system?
• Building Climate-Resilient Surface Water Treatment Plants

  What does it actually cost to build climate resilience into a water treatment plant? The answer depends on the right analytical framework.
