Over the next few months we will be studying Flint water quality issues, in conjunction with all parties who are interested in this subject. i xxxEND_PAGE:deq25_b075_0798_0976_019 We will be launching our web page to publicly report results of our work. We visited Flint last week and collected a lot of samples from the distribution system, and we are also doing a lead in water study with residents, to complement that which was recently conducted by the city under the LCR. Just giving you a heads up on this, and | hope you can give me a point of contact with each of your agencies. Dependent on what we find, it might be desirable to touch base, in advance of our releasing certain findings. We also intend to collaborate with all parties, in an open manner, to the extent that is possible, as our study progresses. Mike, | think | met you a few years back at a Michigan AWWA event, and Rachel, you were kind enough to send me the coliform/E.Coli data last week. Adam, 1 am not sure if | have ever met you or not.
