In the latest fallout from Flint, Michigan\u0026#039;s public health crisis of lead poisoning its drinking water, Gov. Rick Snyder on Tuesday said he was \u0022very sorry\u0022 and the state\u0026#039;s top environmental official resigned. One advocacy group, however, says that full accountability and transparency for this \u0022man-made catastrophe\u0022 are still absent.That catastrophe began in April 2014, as the Rust Belt city was under control of an emergency manager, and it moved its water supply from the Detroit system to the Flint River without the proper corrosive controls.\u0026nbsp; Lead leached from pipes, putting thousands of the city\u0026#039;s children at risk of brain damage from the contamination and prompting local outcry.\u0026nbsp; A local pediatrician has called it an \u0022emergency\u0022 situation that is \u0022alarming and absolutely gut-wrenching.\u0022The latest developments are in response to initial findings released by a Snyder-appointed task force charged with looking into how and why the crisis came to be. The body put\u0026nbsp; most of the blame on Michigan\u0026#039;s environmental regulatory agency.In a letter (pdf) addressed to Snyder, Flint Water Advisory Task Force members write, in part,We believe the primary responsibility for what happened in Flint rests with the Michigan Department of Environmental Quality (MDEQ). Although many individuals and entities at state and local levels contributed to creating and prolonging the problem, MDEQ is the government agency that has responsibility to ensure safe drinking water in Michigan. It failed in that responsibility and must be held accountable for that failure.The letter goes on to fault a \u0022minimalist approach\u0022 in the Office of Drinking Water and Municipal Assistance (ODWMA) at MDEQ \u0022to regulatory and oversight responsibility [that] is unacceptable and simply insufficient to the task of public protection\u0022; and states that the \u0022agency\u0026#039;s response [to public concerns] was often one of aggressive dismissal, belittlement, and attempts to discredit these efforts and the individuals involved.\u0022It further states that the agency\u0026#039;s decision not to call for \u0022optimized corrosion control treatment\u0022 as per the federal Lead and Copper rule \u0022led directly to the contamination of the Flint water system.\u0022On Tuesday, both Dan Wyant, director of the MDEQ, and Brad Wurfel, DEQ spokesman, resigned.Synder said in a media statement that it was \u0022appropriate to accept \u0022 Wyant\u0026#039;s resignation, adding, \u0022I want the Flint community to know how very sorry I am that this has happened. And I want all Michigan citizens to know that we will learn from this experience.\u0022He acknowledged that \u0022many Flint citizens are angry and want more than an apology,\u0022 and said, \u0022When it comes to matters of health and quality of life, we’re committed to doing everything we can to protect the well-being of our citizens.\u0022But the Lansing-based group Progress Michigan says that the people of Flint still need justice.\u0022So far under Gov. Rick Snyder’s watch, there has been zero accountability in this crisis and that continues today,\u0022 said Lonnie Scott, executive director of Progress Michigan. \u0022Dan Wyant gets to walk away from this crisis, but the people of Flint do not. There\u0026#039;s a lot we don’t know about this man-made catastrophe.\u0022What did Gov. Snyder know and when did he know it? We need complete transparency so that justice for the families of Flint can be realized and the proper people can be held accountable. All documentation related this this crisis needs to be released to the public immediately,\u0022 Scott stated.
