And so we went from lake here on which we gap through a pipe from Detroit. To going to the Flint river in corrosion control wasn't put in place we have an aging infrastructure here in the city of fun like every place else almost throughout this country lit seeped into the water system. That was what happened as a result of not having corrosion control even though the state has told us we could start drinking water now because of the test results. I'm saying now I'm not signing off on it yet. I would say the quality of my water matches or exceeds most of the water in the state in this from the country. When it happens to it once it gets to the home this is kind of out of our control. I can tell you the water coming out of plant meets all the requirements what do you trust. That it becomes a matter of personal preference at a certain point. Still pulling out live pipe should have that potential for Lynn to Leach into the water system. And so we want to err on the side of caution and if it takes longer and we have to stay on bottled or filtered water accurate they do grant because I think people will feel more comfortable.

I was just one community in this fight it's you helped in this crisis rather that you helped uncover one study recently found three housing communities and our country. Have led in the water at higher levels than you found in plant that's really something. Yet historian Lynn really lies like iceberg and once that came apart.
