I entered the water-treatment business in residential softener sales. As my knowledge and responsibilities grew, I moved into commercial systems and became increasingly interested in high-purity water—the part of the business where the technical demands were greater, the available guidance was limited, and mistakes were expensive.

At that time, most of the practical literature on deionization and resin systems consisted of supplier bulletins and short technical papers. Membrane technology was still developing. I studied everything I could find, tested what worked in the field, learned from failures, and helped improve both our treatment methods and the quality of service we could provide.

I became active in the Indiana Water Quality Association because I wanted to learn from people who knew more than I did. The industry was then dominated by small independent companies. Many were highly professional, but there were also operators whose sales practices damaged public trust. Technical knowledge was often guarded as a competitive advantage rather than shared for the benefit of the industry.

That experience led me to the national Water Quality Association, where I found broader technical exchange and an industry undergoing rapid change. High-purity water was becoming essential to kidney dialysis, printed-circuit-board rinsing, medical-implant manufacturing, laboratories, and other demanding processes. There were relatively few companies in that field and fewer still with genuine technical depth. I became convinced that high-purity treatment offered the company a way to lead rather than follow, and I made it a professional priority to understand the chemistry, equipment, controls, and service discipline required to do the work correctly.

The company ultimately developed a strong reputation in high-purity water treatment. More important to me, the work reinforced a lesson that runs throughout this book: no one in water treatment knows everything. The strongest professionals continue learning, verify what they think they know, and share knowledge without sacrificing ethics or technical discipline.
