The Augmented Operator: Navigating The Intersection Of AI And The Water Sector Workforce
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.  Continue Reading..

The AWWA Said $2.4 Trillion. It Missed The Compound Interest.
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.  Continue Reading..

Winter's Alarmingly Low Snowpack Offers A Glimpse Of The Changing Rhythm Of Water In The Western U.S.
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.  Continue Reading..

Is Monitoring Of Total Or Free Chlorine A Better Option For Dechlorination Control?
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.  Continue Reading..

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?  Continue Reading..

Automatic Enrollment Supports More Efficient Lead Service Line Replacement
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.  Continue Reading..

The Future Of In Situ Chemical Oxidation For Targeted Solvent Destruction
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.  Continue Reading..

EPA Concludes Drinking Water Has Been Free Of Fuel Contamination Since 2022, In Wake Of Red Hill Release

The U.S. EPA released its final drinking water report on the Joint Base Pearl Harbor-Hickam (JBPHH) and Aliamanu Military Reservation (AMR) public water systems, which were impacted by the 2021 fuel release from the U.S. Navy-owned Red Hill Bulk Fuel Storage facility in Honolulu.

Water, Water Everywhere – But How To Find It?

A new study finds that commercial satellite imagery data often outperforms public data sets when identifying surface water, but that public data sets may be better at detecting water hidden by forest cover.

Xylem Introduces The YSI THM 1000 Analyzer For Rapid, On-Site Measurement Of EPA-Regulated Trihalomethane Compounds

Xylem, the global leader in water treatment and transport technologies, introduces the YSI THM 1000, a new on-site analytical system that measures trihalomethane concentration at ppb levels in less than 30 minutes without tedious sample preparation. An EPA-regulated disinfection by-product, trihalomethanes, or THMs, are carcinogenic environmental pollutants that can occur in drinking water as a result of chemical reactions between naturally occurring organic material and chlorine added as a disinfectant. Drinking water treatment plants and water distribution facilities routinely monitor THMs.

Research Shows Cast Iron Pipes Can Temporarily 'Reseal'

Technical research commissioned by UK Water Industry Research (UKWIR) and conducted by the University of Sheffield has provided a breakthrough in understanding how and why cast iron pipes fail.

National Water And Sewer Bills Rise 5.1%, Outpacing Inflation As Utilities Face Rising Cost Pressures

U.S. household water and sewer bills hit a five-year high in 2025, rising 5.1% and outpacing inflation, according to Bluefield Research, a leading provider of global water market data and insights. Bluefield’s annual U.S. Municipal Water & Sewer Rate Index benchmarks utilities in 50 cities nationwide and reveals a 24.2% cumulative five-year increase—highlighting mounting cost pressures on utilities and ratepayers alike.
