Many Cities Buried Urban Streams. Here's How To Bring Them Back
As many cities developed, streams that once flowed on the surface were buried underground to make way for growing infrastructure. However, as heavier rainfall, extreme weather and aging infrastructure place growing pressure on cities, these buried streams could become part of the solution. Restoring streams to the surface — a practice known as stream daylighting — can help manage stormwater, restore habitats, and create greener, more...  Continue Reading..

Inside Zero Liquid Discharge Systems: The Technology Driving Industrial Water Reuse
Zero liquid discharge (ZLD) is evolving from a wastewater-compliance strategy into a high-recovery separation platform built around reverse osmosis (RO), high-pressure membranes, thermal concentration, membrane distillation (MD), crystallization, sensors, and process controls. Its objective is measurable: maximize water recovery while converting dissolved salts into solids rather than producing a final liquid reject.  Continue Reading..

From Warning To Reality: Lessons From The Latest OT Attacks On Water Utilities
On July 10, I published an article warning that water and wastewater utilities had become prime targets for state-sponsored cyber actors, describing how attackers exploit internet-exposed PLCs, how the IT/OT divide leaves organizations vulnerable, and why the sector needed to act before an incident forced their hand. Today, that scenario is no longer hypothetical.  Continue Reading..

Advanced Water Treatment Strategies Help Data Centers Manage Cooling Water At Industrial Scale
Data centers are evolving into industrial-scale thermal-management facilities as artificial intelligence (AI), high-performance computing (HPC), cloud platforms, and accelerated computing increase rack power density. Modern AI racks can exceed 50–120 kW per rack, creating substantially higher heat-rejection requirements than conventional enterprise infrastructure. ASHRAE's (American Society of Heating, Refrigerating and...  Continue Reading..

From Diagnosis To Decision: Four Pillars Of Actionable Pipeline Intelligence
Aging underground networks require actionable intelligence to prioritize maintenance. Combining flexible screening, accurate spatial positioning, and rapid data access helps utilities pinpoint critical defects, reduce operational disruptions, and optimize long-term capital improvement planning.  Continue Reading..

Putting Pipelines On The Map: How Location Data Strengthens Modern Asset Management Programs
Incomplete pipeline records jeopardize modern utility management. Precise spatial mapping and elevation data protect underground infrastructure, reduce utility strikes during excavation, and enhance digital models to enable targeted, cost-effective infrastructure maintenance.  Continue Reading..

How To Manage Warm-Season Biological Upsets In Wastewater Lagoons
The rate of biological activity in a treatment lagoon is largely a function of water temperature. Once the water rises above roughly 59 °F (15 °C), metabolic rates increase across the entire microbial and invertebrate community.  Continue Reading..

Colorado River Water Conservation Efforts Get Only Halfway To A Solution
In August 2026 the nation’s two largest reservoirs, Lake Mead and Lake Powell, both on the Colorado River, hit their lowest levels since they first began to be filled in 1936 and 1963, respectively. The federal government and the seven Colorado River basin states have been unable to reach an agreement about who should reduce water usage by how much to avoid catastrophic declines in lake levels.  Continue Reading..

Sample Collection And Storage: Protecting Water Quality Results From The Start
Flawless analytical procedures mean little if samples are compromised before testing. Discover how proper container selection, representative collection techniques, and rigorous preservation protocols prevent pre-analysis error to ensure defensible, accurate water quality results.  Continue Reading..

Reverse Osmosis Gets Smarter: New Technologies Target Energy Use And Membrane Fouling
Nearly 45–60% of a reverse osmosis (RO) plant's operating cost is linked to energy consumption, while membrane fouling can reduce productivity by 15–40% and increase cleaning costs by thousands of dollars annually. The newest generation of RO systems is therefore focused on reducing energy demand, extending membrane life, and using intelligent monitoring to predict fouling before performance declines.  Continue Reading..

$7.9 Million NSF Investment Brings Vermont Researchers Together To Address 'Forever Chemical' Contamination

The U.S. National Science Foundation has awarded $7.9 million to establish the PFAS Environmental Research Network (PERN), a four-year initiative bringing together Vermont researchers, educators, students, and state partners to better understand and address environmental chemical contamination.

EPA Releases Final UCMR 5 Drinking Water Data For PFAS And Lithium

On August 27, the U.S. Environmental Protection Agency released the final set of national drinking water data collected under the fifth Unregulated Contaminant Monitoring Rule (UCMR 5) for 30 chemical contaminants: 29 PFAS plus lithium. The data collected under UCMR 5 improves understanding of the prevalence and amount of 29 PFAS and lithium in the nation’s drinking water systems.
