  1. DEXSORB® Regeneration And Concentration Of PFAS Waste 4/2/2026

    DEXSORB is a regenerable adsorbent media offering a cradle-to-grave solution in per- and polyfl uoroalkyl substances (PFAS) treatment. Effective desorption of PFAS from spent media is not only a critical step for enabling sustainable media reuse, but also for concentrating PFAS waste for its safe and cost-effective destruction.

  2. DEXSORB® For PFAS And Organic Micropollutants 4/2/2026

    DEXSORB is a novel adsorbent made from crosslinked β-cyclodextrin polymers. The media features uniform 0.78 nm hydrophobic cavities that selectively adsorb organic contaminants in the 150 – 1000 Dalton molecular weight range. DEXSORB is available in two formulations to adsorb (A) PFAS exclusively, or (B) PFAS + organic micropollutants (OMPs) in combination. While DEXSORB and GAC operate by the same mechanism of adsorption, and share similar physiochemical properties, DEXSORB possesses multiple properties that provide for superior PFAS removal and waste handling.

  3. Senior Living Community Water Supply Protected By An AVT EZ Valve 4/2/2026

    Maintaining water service during infrastructure upgrades is critical for community safety. Innovative insertion technology allows for the creation of permanent isolation points on live pressurized lines, ensuring uninterrupted supply while enhancing long-term grid reliability.

  4. The Augmented Operator: Navigating The Intersection Of AI And The Water Sector Workforce 4/2/2026
    The water sector is facing a convergence of crises. On one side, an estimated 30–50% of the utility workforce is projected to retire within the next decade, taking with them irreplaceable institutional knowledge. On the other, AI is no longer future technology; it is being deployed today for operations. These two forces are colliding at precisely the moment utilities can least afford disruption.
  5. The AWWA Said $2.4 Trillion. It Missed The Compound Interest. 4/1/2026
    Einstein once said of compound interest, "He who understands it, earns it. He who doesn't, pays it." The same logic of compounding applies to the organic sediment accumulating on the floor of your drinking water reservoir. The longer you wait to address it, the more exponentially expensive it becomes to fix.
  6. Winter's Alarmingly Low Snowpack Offers A Glimpse Of The Changing Rhythm Of Water In The Western U.S. 4/1/2026
    The April 1 snowpack measurement has long been the single most important number in western water management, considered a strong proxy for how much water the mountains are holding in reserve. But in 2026, that savings account has been woefully deficient.
  7. GeoTree - Water Conveyance Tunnel Rehabilitated With GeoSpray Geopolymer 4/1/2026

    Historic arched tunnels require specialized structural restoration to address severe infiltration and mortar loss. Trenchless geopolymer technology provides a conformable, high-strength lining that stabilizes aging brick and granite structures, ensuring long-term hydraulic performance and structural integrity.

  8. GeoTree - Large Diameter Sewer Re-Built And Re-Lined 4/1/2026

    Trenchless rehabilitation provides a sustainable alternative to traditional excavation for failing sewer infrastructure. High-performance geopolymer liners offer structural restoration in highly corrosive environments, minimizing urban disruption while preventing environmental hazards through efficient, spray-applied application techniques.

  9. Understanding The Different Phosphorus Tests 3/30/2026

    In wastewater treatment, phosphorus testing can quickly become confusing. For example, there are three different tests. So, which test was performed? Test results can be displayed in two different forms. So, which form was utilized? Tests can measure both particulate and dissolved phosphorus. So, was the sample filtered?
