The Environmental Detective Who Revolutionized Water Treatment
In the world of environmental science, few researchers have left as profound a mark on our daily lives as William H. "Bill" Glaze. As a pioneering scientist, educator, and philosopher, Glaze dedicated his career to solving one of humanity's most pressing challenges: how to ensure access to clean, safe water 4 .
Advanced oxidation processes for water decontamination and environmental protection.
Founded the Carolina Environmental Program and advocated for interdisciplinary approaches.
At the heart of Glaze's most significant contributions lies a remarkably simple but powerful concept: using hydroxyl radicals to destroy water contaminants 4 .
One of Glaze's most impactful research endeavors focused on solving a particularly stubborn environmental problem: RDX contamination 2 .
| Treatment Method | Key Findings | Nitrogen Conversion |

| UV/H₂O₂ | Enhanced degradation rates | Not specified |
| Ozone alone | Formation and subsequent disappearance of formamide and urea | Not specified |
| Ozone/H₂O₂ | Highest degradation efficiency; complete disappearance of intermediates | ~50% conversion to nitrate |
| UV/Ozone | Combined benefits of photolysis and oxidation | Not specified |
| Reagent/Technology | Primary Function | Research Application Examples |
|---|---|---|
| Ozone (O₃) | Primary oxidant that also generates hydroxyl radicals | Direct oxidation, hydroxyl radical production via decomposition |
| Hydrogen Peroxide (H₂O₂) | Hydroxyl radical precursor when combined with ozone or UV | Enhancement of ozone-based systems, UV/H₂O₂ processes |
| Ultraviolet Light (UV) | Energy source to break chemical bonds and activate oxidants | Direct photolysis, peroxide decomposition, catalyst activation |
| Titanium Dioxide (TiO₂) | Semiconductor photocatalyst activated by UV light | Heterogeneous photocatalysis for contaminant destruction |
William H. Glaze's career exemplifies how dedicated scientific research, coupled with practical vision, can directly improve human wellbeing and environmental health .
"His pioneering work on advanced oxidation processes provided water treatment professionals with powerful tools to combat an array of water contaminants, from industrial chemicals to explosive residues."
