41. 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.
42. 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.
43. Is Monitoring Of Total Or Free Chlorine A Better Option For Dechlorination Control? 3/26/2026

    Accurate dechlorination control requires monitoring all residual oxidants that threaten membrane integrity. Total chlorine analysis provides the necessary precision at ultra-low levels, ensuring comprehensive protection against oxidative damage while maintaining reagent stability during intermittent system operations.

44. Why Colorado River Negotiations Stalled, And How They Could Resume With The Possibility Of Agreement 3/26/2026
    The five most common sources of conflict between people are values, data, relationships, interests, and structure. The current Colorado River negotiations include all five.
45. Cooling The AI Revolution: The Critical Role Of Intelligent Pumps 3/25/2026

    Intelligent metering pumps enable precise water treatment and predictive maintenance in AI data centers, helping prevent scaling, reduce downtime, and maintain efficient liquid cooling for high-performance systems.

46. Florida Utility Saves 2,080 Man-Hours With Just 5 Sensors 3/25/2026

    Continuous water quality monitoring helps utilities offset workforce shortages, reclaim thousands of labor hours, improve compliance, and gain real-time insights that enhance system performance and reliability.

47. Designing Resilient PFAS Treatment Strategies For Water Agencies 3/24/2026
    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?
48. Automatic Enrollment Supports More Efficient Lead Service Line Replacement 3/24/2026
    Many utilities plan lead service line (LSL) replacements using block-by-block or neighborhood approaches to maximize efficiency. In practice, these projects often stall during customer engagement and property access phases. Automatic enrollment reduces the time and resources required to collect paperwork and makes it easier for utilities to schedule and complete replacement projects.
49. The Future Of In Situ Chemical Oxidation For Targeted Solvent Destruction 3/24/2026

    The U.S. EPA’s 2026 trichloroethylene (TCE) compliance deadlines are now forcing a concrete shift toward source-zone destruction. In situ chemical oxidation (ISCO), sequenced with enhanced bioremediation, is proving to be the most credible path to groundwater contaminant rebound mitigation.

50. Surface Water vs. Groundwater: Strategic Infrastructure Tradeoffs For Growing Communities 3/23/2026

    What's really at stake when choosing between surface water and groundwater? The answer shapes water security for decades.
