During a recent Water Online Live event, I sat with a panel of industry experts to examine the transition from reactive crisis management to a proactive, adaptive resilience framework.
Drinking Water Contaminated With 'Forever Chemicals' During Pregnancy Linked To An Increased Risk Of Childhood Asthma
While most of us are routinely exposed to low levels of PFAS, some communities are exposed to far higher levels from nearby pollution sources. A new study shows that in one of these at-risk communities, children were more likely to develop asthma if their mothers were exposed to very high PFAS levels during pregnancy.
The Pragmatic Shift In Source Water Protection: Moving From Symptom Management To Root-Cause Accountability A shift in how we approach source water protection is long overdue. Currently, we are trapped in a cycle of escalating costs, forced to treat symptoms like algae and invasive weeds expediently with chemicals while the underlying risk in the reservoir compounds. True risk management requires breaking this cycle.
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.
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?
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.
When Drinking Water Raises Bigger Questions About Brain Health And Environmental Risk
A new study linking certain groundwater sources to higher Parkinson’s risk underscores a broader question for the water sector: how environmental exposures in drinking water may influence long-term health.

Sewage Treatment Mini Train System: WWT-50

The highly scalable newterra WWT-50 Sewage Treatment Mini Train System is designed for rapid mobilization to serve camps of 200 to 800 people. These efficient plants are configured in trains that allow modular expansion and easy redeployment of assets. Each base configuration consists of two 40' containers that provide 50 m3 (13,200 US gal) of treatment capacity – enough for 200 people. Supplementing the base system with one 40' Adder container doubles capacity to 100 m3 for up to 400 people.

Emerging Pollutants: The Role Of Activated Carbons

The presence of active pharmaceutical ingredients, radio-opaque substances and endocrine disrupting chemicals in raw water sources is a relatively new emerging issue in relation to drinking water quality. However, the influence of pollutants on health and general well-being is becoming apparent with the incidence of carcinoma increasing and fertility rates being affected. A solution for the efficient removal of these substances from water use by production sites is required.

ETS-UV™ For Water Reuse

Given the critical shortage of drinking water in many regions, advanced treatment and reuse of wastewater is becoming increasingly common as municipalities address water demands and shrinking supplies.

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.

Desalination Of Sea Water

Desalination is the name given to processes that remove salt from water

Aqueous Electrostatic Concentrator

The Aqueous Electrostatic Concentrator's (AEC) modular design provides a small footprint and low energy consumption, and it can be skidded, trailer-mounted, or custom configured to fit into existing spaces.
