Dear Tracy Jo, Thank you for the information. Regarding the second document (p. 9), | see that it contains instructions for LCR compliance monitoring, but it seems that it is written specifically for schools. Do community water systems in MI include school samples in LCR compliance calculations?

Ms. Lambrinidou : To follow up regarding your inquiry: The first document (pages 1 — 8) is the draft working document that we created to sample schools within the City of Flint that are on the city’s water system. The draft provided as part of the FOIA is dated November 6, 2015. That working draft continues to be updated. The second document (page 9) is the instructions document that we provide to community water systems to assist them with their lead and copper compliance monitoring. | believe this document was created in 2011 and was in use until this week. A revised sampling instructions document is posted on our website at http://www. 2015_508290_7.pdf. The third and fourth documents are currently in use by our Noncommunity water supply program. Both documents are dated at the bottom of the page. One has a 9/2013 date and the other has a 10/2012 date. These would be the dates that the document was created and/or revised. Hope this is helpful.
