Prior to writing “What’s in my Water?” David owned multiple water filtration locations in the Midwest. It was during that time that he saw a report from that said approximately One Million people become ill every year and an estimated 100,000 people die due to infectious drinking water and referenced the Center for Disease Control (CDC). This started David on his quest to find the truth about our nation’s drinking water quality. This quest led him to research through thousands of pages of information and data from the Environmental Protection Agency (EPA), the Center for Disease Control (CDC), the American Journal of Public Health, the Department of Public Health and many more sources. At the request of numerous associates David compiled the important elements of his research into a report that led to the writing of "What's in my Water?"
