I am an internationally recognized authority on drinking water quality, treatment methods, health effects, distribution system operations ,and water reuse. In this regard, I authored more than twenty-five technical books and manuals, and at least seventy scientific articles on these subjects. This expertise established my status as an expert advisor retained by the US Environmental Protection Agency, NASA, the National Academy of Science, and the Government of Singapore.

For nearly fifteen years I managed Denver’s Direct Potable Water Reuse Demonstration Project. The Project’s comprehensive scientific studies showed that drinking water could be reliably and continuously produced from unchlorinated secondary treated wastewater. The integral research included a two-year chronic lifetime whole-animal health effects study on generations of test animals. This unique study has never been repeated on any drinking water supply. The results of the program have since been used by water systems considering using treated reclaimed wastewater as a potable water supply.
