About Us

David De John, the author of What's in "My Water?" has been interviewed by multiple publications including: Wall Street Journal, Crain's Business, Chicago Tribune, Entrepreneur Magazine, Southtown Newspaper, The Robb Report, TV and Radio Talk Show's and numerous other media outlets.

David has been requested as a speaker on What’s in my Water? topics for health industry conferences, educational seminars at municipal venues, health and nutrition venues along with providing information to health care providers and medical facilities. He has been called upon to review findings from the Department of Health investigations relating to Public Water Supplies for a major newspaper.

David started in the industry when he opened water filtration locations in Northeast Illinois and Northwest Indiana. Like most people in the industry, he focused on selling water softeners as the answer to most water problems. The workshops David attended all focused on the same thing: how to sell more equipment. In fact, one speaker stressed not talking about contaminants in drinking water, because it will only confuse people. It was as if there was a concern that people would get concerned and actually ask, What’s in my water?
