Jim, This topic was on the agenda of the Region 5 States conference call yesterday. Illinois, Indiana, Ohio and Wisconsin do not have active school sampling programs for lead. Only Minnesota has an on-going program, and it is being conducted through their Department of Education even though their drinking water program is in their Department of Public Health. Minnesota said they would circulate additional information about this program to the other states. | asked if we could get an estimate of the resources they expend, which we may have to obtain in a follow-up conversation. Minnesota did say they even provide funding for lead abatement measures, which include dealing with corrosion issues in schools that are connected to municipal water (fixture replacements, etc.) as well as schools that are classified as noncommunity public water systems (installing corrosion control treatment). | will circulate the additional information when it is distributed, or contact Minnesota directly if it doesn’t arrive soon.

Date: Wednesday, December 09, 2015 2:47:17 PM FYI. Flint’s additional corrosion control inhibitor feed is now up and running. As a reminder this is on top of the corrosion inhibitor already present in the water purchased from DWSD. Stephen Busch, P.E.

Revised. SHe the note on page two regarding stagnation times greater than 24 hours. i would orefar to use L& hours, fut the EPA notes recommended 24 hours sol went with that. Please int rne know if you have any other comments. Jirn ~ f think this can be shared with EPA aven if staff have further comments.

Updated lead and copper sampling instructions for residents/customers. We have modified our instructions to address concerns raised. We have not vetted this through any district staff to see if they have any other recommendations. This could be done concurrently with EPA’s review. xxxEND_PAGE:deq15_b768_2732_2732_1

FYi- revised version. I'm meeting at 2pm with Kory, Michelle and Jennifer,

Date: Wednesday, November 18, 2015 6:31:00 PM Because this media inquiry appears to be in response to Flint, | am asking if | should return the call or refer it to the Public Information Office? | have heard that this media outlet has contacted at least one other public water system to ask about the status of their LCR compliance.

Let me get back to you on this.

Date: Thursday, November 12, 2015 5:09:00 PM Jim, Steve Via is the Regulatory Affairs Manager for the American Water Works Association in Washington, D.C. He contacted us earlier this month to provide some information regarding LCR implementation in other states and in certain water systems that are members of their association. I contacted him again earlier this week to ask for documentation about other state programs. During our conversation, Steve indicated that the national AWWA is planning to have the topic of lead in drinking water and Flint on the agenda of their 2016 Annual Conference next June, which is in Chicago. He mentioned that there may be an opportunity for Michigan DEQ to provide their story. Below is a follow-up message I received today indicating that Darren Lytle from EPA and a member of the Flint Technical Advisory Workgroup/Committee is planning to present at their conference, and Mike (Glasgow, I believe) is likely to give a presentation as well. Steve is wondering if we would like a slot on the panel/session. I told him I would elevate the request, but I wasn't sure if we would be able to do so or if we were able, who would be doing such a presentation. Is this request to speak something we can tentatively agree to do at this time, with the caveat that we would have to cancel if circumstances should warrant doing so before next June? Let me know what you think. Thanks, Richard

The attached came off of the Mass. page. Blood levels in children are not significantly impacted by lead levels in water that are 15 ppb or lower xxxEND_PAGE:deq20_b10_223_431_019 presented a risk for bottle-fed infants. The lead studies discussed above exclusively assessed lead in water, and tap water was the only source considered as the cause of the increased BLL. One landmark U.S. observational study conducted during the 1990s studied 183 urban children aged 12-31 months (37%, 12-18 months; 31%, 18-24 months; 33%, 24-31 months) (57). Of these children, 63% had BLLs <10 g/dL, 20% had BLLs of 10-14 yig/dL, 8% had BLLs of 15-19 pg/dL, and 3% had BLLs >20 g/dL. The study evaluated lead in home foundation perimeter soils, potable water, paint, and house dust. Lead-contaminated house dust was the major contributor to BLLs 210 ug/dL. However, the study reported that although lead-contaminated water had a statistically significant effect on children's BLLs after adjusting for other sources of lead exposure, no statistically significant contribution for drinking water could be discerned at levels below the current EPA action level of 15 ppb (57). Lead dust as a primary source of lead for children with increased BLLs was further demonstrated in a subsequent pooled analysis of 12 studies; floor dust lead levels as low as 5 ug/ft2 were associated with 5% of enrolled children having a BLL >10 ug/dL (58). xxxEND_PAGE:deq20_b10_223_431_020
