I see a lot of talking going on in this thread, by people who have obviously been getting their information from the national news. I'd like to make a couple of points here. For reference, I went to college in Flint, still have deep ties to that area, and still live in Michigan now.
1) Please don't attempt to push your own personal political agenda by making this a partisan issue. It isn't one. I would go so far as to state that there are people in certain parts of the media network that are seeing this as an opportunity to erode support for the Republican government that is currently in place, and have not been squeamish about misrepresenting certain facts to make that happen. See below. In short, please keep the politics out of it. If you want political discussion there are other boards where you can get it.
1a) There were many failures in government that lead to this problem developing- but not all of them were Republican state officials. Former Flint mayor Walling contacted the (recently resigned...) EPA administrator for the Flint district and was rebuffed.
2) It is 100% true that there has been a recent outbreak of Legionella in the mid-Michigan area that corresponds with the change of Flint's drinking water source. What the national media is NOT reporting, however, is that a significant portion of the people who contracted Legionnaire's disease, including some of the resulting deaths, during this period are not residents of the part of Genesee County where drinking water is provided by the river. The highest peak of the Genesee County Legionella outbreak still represents fewer cases than in other areas of the state, including Oakland county, which does not get its water from the Flint River system. (55 cases in Genesee County in 2015; 51 cases in Wayne County and 65 cases in Oakland County in 2013) Point is, was (is..) there a Legionella outbreak in the Flint area? Yes. Does it represent a huge outlier relative to Legionella cases in other parts of the state? Not really. Can the Legionella outbreak be CONCLUSIVELY tied to the change in source of Flint's water? NO.
3) Someone has already covered this, but the source of lead contamination is not the Flint river water, or the city mains- it is the drops that connect the mains to individual buildings and homes. Some of the children who have suffered extreme lead exposure live on the same block as other children whose blood tests resulted in zero lead found. This is obviously a huge problem, and in no way am I attempting to downplay that, but it is a huge problem that has to be diagnosed on a case-by-case basis- it is not nearly as simple as the media is depicting it to be.
