In Water Confidential, Susan Blacklin revisits the important work of her late ex-husband, Dr. Hans Peterson. Beginning in 1996, Peterson, growing frustrated with his work in government funded research in Saskatchewan, brought attention to the desperate need for equal access to safe drinking water after a visit the Yellow Quill First Nation. In response to the issue, he developed biological technology for effective water treatment, still in use today. Peterson and Blacklin joined forces with scientists from around the world to establish the registered national charity, the Safe Drinking Water Foundation. Advocacy became a high priority when they discovered a variety of challenges to their mission, including questionable government practices that were blocking the reality of safe drinking water in First Nations communities. In this passionate and timely memoir, Blacklin shares her experiences with fundraising, activism and lobbying work and reveals the complexities of negotiating between cultures, communities and the provincial and federal government.
