In Water Confidential, Susan Blacklin (formerly Sue Peterson) 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 health inspector encouraged him to 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. The SDWF developed accredited education programs for schools across Canada, while also educating the general public and Water Treatment Operators from Indigenous communities. 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. As committed activists, it became their life's work to ensure that access to Peterson's technology was available to all rural and First Nations communities. Thirty years later, the majority of First Nations communities in Canada continue to face atrocious health issues as a result of unsafe drinking water. Blacklin, now retired, shares her deep concerns at the indifference, corruption, and lack of due diligence from all levels of government in response to the safe water movement. She echoes the work of the SDWF stating that Canada needs to implement federal drinking water regulations, and that a responsible government should use rather than abuse science when accurately determining Boil Water Advisories and addressing the deplorable state of access to potable water. In this passionate and timely memoir, Blacklin shares her experiences with fundraising, activism and lobbying work. She reveals the complexities of negotiating between cultures, communities and the provincial and federal government. Blacklin emphasizes that ensuring safe drinking water to each and every First Nations community should be the top priority toward reconciliation with Indigenous people of Canada.
