Hi, all. Sorry to have bugged you about this; | thought Mike and Darren wanted something more in detail that what was provided in the OEL, and they have the OEL. | asked if they need further detail than this. We'll find out. Jennifer

| wonder if we should consider preparing a similar document for possible distribution to other water systems that discusses the issues that we have been facing in Flint and the action plan that is being put in place today. | think we published this document in Water Works News. Let’s discuss next week. xxxEND_PAGE:deq14_b0162_0868_0868_1

Date: Wednesday, September 30, 2015 3:07:23 PM ODWMA is receiving a lot of calls with questions from Flint residents concerned about the safety of their drinking water. If you receive one of these calls, our message should be consistent — the drinking water distributed to city customers currently meets all drinking water standards and is considered safe. However, there is no safe level for lead. The fact that Flint meets the drinking water standard is based on an evaluation of the effectiveness of their treatment system to minimize lead leaching from plumbing materials. Compliance does not mean that under certain conditions that some homeowners may still have water in their domestic plumbing that has leached some lead from lead pipes or lead solder. The only way for a resident to know if they may be exposed to lead leaching from their plumbing system is having a sample from that residence analyzed for lead at a certified laboratory. The DEQ laboratory is not providing that service at no cost. The city of Flint currently is accommodating requests from residents without charging them, but the residents have to go through the city to arrange that sampling, and the city may have a backlog right now. If the caller has a result that indicates lead is present, or in the absence of a result, our advice should be to minimize any stagnation of the water before consumption, even without knowing if they have plumbing that contains lead. You could tell them they can do so by letting a faucet run for a few minutes or until the water is cooler (don’t set a time — it can be so variable) and then use it for drinking or cooking. Please be polite and empathetic if you receive one of these calls. | also want to thank you for the effort you have made to respond to this issue. It is noticed and appreciated. In recognition of your performance, | have arranged for you to receive a 2 percent merit increase starting tomorrow.

We need to get answers Wednesday. Someone needs to contact Flint and determine the validity of these claims without sounding too accusatory. Did the city mail sampling kits to the same homes in the last two rounds of lead & copper monitoring? If not, why? Do they have a record that these sites have lead services or lead plumbing? If not, why did they certify them as meeting that criteria when they submitted the results? Did they tell Mark Edwards or anyone else that their sampling kits are distributed randomly? Did they mean randomly among lead service line properties? Those are just the ones | can think up at this time. ’m sure there are others we could ask.

| think it is important to point out that the standard is based on water representative of what is in the public distribution system, not site plumbing systems. | had a similar discussion with UofM Flint about levels analyzed in their plumbing system. While the MCLG’s for the various forms is in some cases 0, my understanding is that exposure at 80 ppb is not directly tied to specific health effects, but rather what is essentially feasible for water systems to achieve at the current time while balancing the need for disinfection. Per EPA, EPA has regulated DBPs since 1979 to address health risks posed by a potential association between chlorinated drinking water and cancer, particularly bladder cancer. Current reproductive and developmental health effects data do not support a conclusion at this time as to whether exposure to chlorinated drinking water or disinfection byproducts causes adverse developmental or reproductive health effects, but do support a potential health concern. Although uncertain, the combined health data warrant EPA’s promulgation of the Stage 2 Disinfection Byproduct Rule to provide an incremental step towards mitigating potential risks.

Just had a call from a resident of Flint whose neighbor was told yesterday by the city to not drink the water because the TTHM level at her home was 95 ppb. The caller wanted to know if animals should be consuming the water. | told her she would have to consult with a toxicologist or someone familiar with veterinary medicine. | told her animals are less susceptible to some contaminants but more so to others, but as engineers and analysts, we were not the ones that would make that decision — we just pass it on if we find out. She asked about other TTHM sampling locations and where they were in the city. | told her to contact one of you, starting with Adam. xxxEND_PAGE:deq04_b580_7196_7564_114 Rennaker, Joanne (DEQ)

| don’t know if you have had any contact with this person and | am unsure that a response is necessary, as it was forwarded as an FYI. It is difficult to determine what is being requested, but it looks like a customer of Flint asked EPA for drinking water quality and when EPA told her to contact her water system, she tried to get the information from the state but contacted WRD. It also sounds like she questions relying upon the local supplier to report monitoring results. You could contact her to see if we can be of assistance or send her a message indicating that we (you) are the source of drinking water information if she doesn’t want to get it from the city.
