What I don't understand is, according to that story, they switched back the water supply to Detroit last October. Why is there still a crisis then? Did that not return the water to safe levels? Doesn't make sense.
Edit: Read through a few of the stories, the problem is Flint's water system is full of lead pipes and the corrosiveness of the water they used from the river has caused them to leach more lead than normal. The real problem is the lead pipes of the city that should have been replaced by the city decades ago. Who knows, maybe lead levels were always above federal standards and the city has somehow hidden that for years, what is sure is that they are above safe standards now and the problem will only be fixed by replacing the infrastructure. Not promising for the residents, very sad story of decades of mismanagement.
