H2O Adventures: From Microbe Hunter to Water Wizardry!

1987: The Beginning of Our Journey

Our journey into the realms of science, engineering, and water safety began in 1987. Driven by curiosity and a desire to make a difference, we embarked on a path that went beyond academic pursuits.

1991: Field Microbiology with Environment Canada

While still in university, my passion for science led me to Environment Canada in 1991. For the next three years, I worked as a field microbiologist, sampling, analyzing, and cataloging pathogen-contaminated water. This early venture into understanding the natural world set the stage for what was to come.

1994-1999: From Dot-Com to H2O

During the Internet boom, I launched a software company, bridging the digital divide for small and medium-sized businesses in Canada and the U.S. Despite the success, my passion for water, science, and engineering called me back.

Industry Legionella Statistics







In 2023, the province of Ontario, in Canada, reported 304 cases of Legionnaires’ Disease, marking a trend of increasing incidences (Ontario Health). Similarly, in the United States, reports of Legionnaires’ disease to the CDC have escalated since 2000, with actual figures potentially 1.8–2.7 times greater than recorded. In 2018 alone, 10,000 cases were officially reported (CDC).

Innovating Legionella Management

Leaving the dot-com world behind, I focused on water treatment. My research revealed that the industry was stagnant, relying on outdated technologies from the ’70s. Determined to innovate, I gathered a team of industrial automation engineers. Together, we aimed to revolutionize Legionella management with advanced, chemical-free solutions that prioritize public health. This was the start of a new chapter, where innovation leads the way in the fight against waterborne hazards.

From Vision to Reality with AquaLyse®

In 2002, ProCare Water Treatment Inc. was founded to address the need for advanced Legionella water treatment solutions. We didn’t just aim to fill a market gap; we sought to redefine it. AquaLyse® Copper Silver Ionization was born, featuring the first software-driven Programmable Logic Controller (PLC) with unique industrial automation capabilities now standard among consultant engineers.
