Grand Canyon's Dragon Bravo Megafire Shows The Growing Wildfire Threat To Water Systems
As wildfire crews battled the Dragon Bravo Fire on the Grand Canyon’s North Rim in July 2025, the air turned toxic. A chlorine gas leak had erupted from the park’s water treatment facility as the building burned, forcing firefighters to pull back. The water treatment facility is part of a system that draws water from a fragile spring. The fire also damaged some of the area’s water pipes and equipment.
What Are Legionella Log Books And Why Are They Important? Implementing and managing a Legionella control regime can sometimes seem daunting and complex. Invariably, a lot of resources, time, and effort are needed to achieve the required standard and provide assurance to senior management and auditors that controls are effective and those that are not are being managed and rectified appropriately.
How ABB's Flow And Digital Technologies Help Bawat With Smarter Ballast Water Compliance
The International Maritime Organization (IMO) sets strict global standards for ballast water management to prevent the spread of harmful aquatic organisms. For companies like Bawat, a Danish innovator in ballast water management, being able to verify ballast water flow measurements quickly, accurately, and from anywhere in the world is essential.
PFAS Policy In 2025: Why It's Time To Go Beyond Remediation The most common techniques for disposing of PFAS may no longer be good enough.
The Uneven Fight Against PFAS In Rural vs. Urban Water Systems Drinking water systems across America face a mounting PFAS threat with starkly different capacities to respond. Large urban utilities typically have ample resources to detect and remove these persistent chemicals from water supplies, while small rural systems operate with tight budgets, skeleton crews, and minimal technical support.
CERCLA And PFAS: What's The Liability For Water And Wastewater Utilities? Federal rules aim to target those liable but may miss the mark. Utilities can redirect the effort — and costs — to those truly responsible for PFAS contamination.
25 Years Of Everglades Restoration Has Improved Drinking Water For Millions In Florida, But A New Risk Is Rising
As the Everglades has shrunk over the past century, South Florida’s water supply and water quality have become increasingly threatened, including by harmful algal blooms fueled by agriculture runoff. Now, the water supply faces another rising challenge: saltwater intrusion.

Reducing And Reusing Water In Steel Manufacturing

The art of manufacturing steel for industries is well over 100 years old. Within this time, the steel business has fulfilled consumer needs, including construction, transportation, and manufacturing. The steel manufacturing process is quite intensive as it requires a lot of water to cool down the application. Steel plants constantly look for strategies that can help sustain the steel for a longer time by efficiently improving water and energy consumption.

ShaleFlow™: A Transportable, Modular Solution For Produced Water Reuse

Veolia has developed ShaleFlow™, a cost-effective transportable solution for reuse of produced water and flowback water from hydraulic fracturing operations.

Activated Carbon And Adsorption Of Trichloroethylene (TCE) And Tetrachloroethylene (PCE)

Trichloroethylene (TCE) and Tetrachloroethylene (PCE) are two of the most common solvents that contaminate groundwater supplies in the United States. Both solvents see frequent use in the extraction of fat, in the textile industry, in the production of various pharmaceutical and chemical products. TCE is also used as a degreaser from fabricated metal parts, and PCE serves as a component of aerosol dry-cleaning solvents.

A Tiny Bit Of PFAS

In the most recent edition of Water Innovations, there is not a single article focused on PFAS. That wouldn't be exceptional if not for the fact that discussion around per- and polyfluoroalkyl substances has so thoroughly dominated the water space lately. And yet, I penned this as an intro to the edition — just "a tiny bit of PFAS" content — because a small portion of PFAS is of the utmost importance in terms of treatment, policy, and cost.
How CERCLA Complicates The PFAS Problem

As states and the federal government attempt to crack down on the proliferation of PFAS and their health consequences with a spate of new regulations, there is one significant upcoming ruling that will have tremendous impact for compliance and costs: the final rule on PFAS CERCLA designation.
