SOURCE WATER RESOURCES

• Applying Two Flood Models To Cross-Check And Improve Each Other — And Maybe Saving A Downstream Village In The Process

  Getting a second opinion is a time-tested piece of wisdom. During a recent project for a municipal water supply utility, we found that this advice also applies to modeling the effects storms have on the municipality’s reservoirs and dams, and the potential flooding impacts downstream of the dams.

• How Satellite IoT Can Enhance Remote Water System Monitoring

  There is a noticeable shift in how monitoring data is being treated across the water sector. It is no longer something that sits quietly in the background of operations, collected for compliance, and reviewed periodically. It is being examined more closely, and more often, by a wider set of stakeholders.

• What Is The Future Of Source Water Protection?

  Water utility managers and municipal leaders have long struggled amid the convergence of several threats to public water supplies. 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.
• 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.
• Why Colorado River Negotiations Stalled, And How They Could Resume With The Possibility Of Agreement

  The five most common sources of conflict between people are values, data, relationships, interests, and structure. The current Colorado River negotiations include all five.
• 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.
