Drinking Water Contaminated With 'Forever Chemicals' During Pregnancy Linked To An Increased Risk Of Childhood Asthma — New Study
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.  Continue Reading..

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.  Continue Reading..

Itron Launches Resourcefulness Digital Badge In Collaboration With UT Austin To Advance Energy And Water Literacy

Itron, Inc. (NASDAQ: ITRI), the intelligent infrastructure provider for modern energy and water management, announced the availability of the Resourcefulness Digital Badge, a free education credential developed by global energy expert Dr. Michael E. Webber and supported by The University of Texas at Austin LBJ School of Public Affairs.

Cyber‑Resilient Infrastructure Starts With Early, Strategy-Driven Design

As adversaries increasingly attack the operational technology (OT) and industrial control systems and networks that keep power flowing, water running, and industrial processes moving, a large majority of industrial capital projects still introduce cybersecurity too late in the development process, or not at all, according to a new global Cybersecurity Report from Black & Veatch and Takepoint Research.

Multi-Million Pound Upgrades Completed At Three West Sussex Wastewater Treatment Works To Improve Water Quality

More than £13m of improvements have been completed at Southern Water’s wastewater treatment works at Forest Green, Balcombe and Ashington.
