Drinking Water Treatment Resources

1. UV, Ozone, Or Chlorine: Which Solution Is Best For Your Treatment Plant? 4/7/2026

   No single disinfection method does it all. Utilities are combining chlorine, UV, and ozone to build more effective, flexible treatment strategies for today’s water challenges.

2. Case Study: Groundwater DWTP (AK) - DEXSORB Full-Scale 3/29/2026

   A DWTP client in Alaska detected elevated PFAS contamination levels in two groundwater wells supplying drinking water to 85 service connections. PFAS concentrations are provided in Table 1, where combined concentration of EPA PFAS6 was detected at 490 to 810 ppt.

3. Is Monitoring Of Total Or Free Chlorine A Better Option For Dechlorination Control? 3/26/2026

   Accurate dechlorination control requires monitoring all residual oxidants that threaten membrane integrity. Total chlorine analysis provides the necessary precision at ultra-low levels, ensuring comprehensive protection against oxidative damage while maintaining reagent stability during intermittent system operations.

4. Designing Resilient PFAS Treatment Strategies For Water Agencies 3/24/2026

   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?

5. Surface Water vs. Groundwater: Strategic Infrastructure Tradeoffs For Growing Communities 3/23/2026

   What's really at stake when choosing between surface water and groundwater? The answer shapes water security for decades.

6. Building Climate-Resilient Surface Water Treatment Plants 3/23/2026

   What does it actually cost to build climate resilience into a water treatment plant? The answer depends on the right analytical framework.

7. How Regulatory Pressure Is Driving Innovation In Surface Water Facilities 3/23/2026

   What does it take to stay ahead of tightening drinking water standards? See how utilities are turning regulatory pressure into smarter infrastructure investment.

8. Designing For Harmful Algal Blooms (HABs) In Surface Water Treatment Plants 3/23/2026

   The Toledo water crisis exposed treatment gaps, highlighting harmful algal blooms as a core design challenge requiring flexible, multi-barrier systems and scenario-based planning.

9. The Future Of Surface Water Treatment In Critical Infrastructure: Why Digital Planning Is No Longer Optional 3/23/2026

   Surface water supplies most urban drinking water, but rising variability and contamination are straining ageing infrastructure—making digital planning tools essential for resilient, future-ready treatment systems.

10. Your Chlorine Sensor Is Lying to You — Here's 65 Days Of Proof 3/17/2026

    The operators at Compton Durville Water Treatment Works thought their chlorine dosing was under control. Their Siemens Depolox membrane sensor showed residuals right at setpoint. The PID loop was doing its job. On paper, everything looked fine. It wasn't.
