SOURCE WATER CONTAMINATION RESOURCES

• The Enzyme Bottleneck: Why Conventional Lake Management Is Failing — And What The Science Says About Genuine Bio-Dredging

  For decades, the dominant framework for assessing and managing lake health has been built around surface water measurements: chlorophyll-a, total phosphorus, water clarity, and the composite Trophic State Index derived from them. These metrics are familiar, standardised, and widely accepted. They are also, according to a growing body of peer-reviewed literature, measuring the wrong part of the lake.

• Ozone Off-Gas: What It Reveals About System Efficiency, Safety, and Design

  Learn how ozone off-gas impacts system efficiency, safety, and performance, and why monitoring and management are critical for optimized water treatment operations.

• UK Reservoirs, Water Shortages, And Legionella Risks Is there a clear link between a less plentiful water supply and an increase in Legionella in our domestic water systems?
• The Devastating Legacy Of Algaecides: Why The Quick Fix Is Failing Our Lakes As warmer months approach, water management professionals must confront the compounding consequences of biocidal algae treatments.
• 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.
• 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.
