FW: Lead Sampling Issues

Thought folks might find these documents informative: Attached to this message are a couple of documents that were prepared over a decade ago that discuss excessive stagnation and sample invalidation under the LCR. They were prepared in response to questions from the Washington Post and other news media about invalidation of some samples collected in the Lansing Board of Water Light service area. The first document is an internal memo that identifies language in the federal preamble to and in EPA guidance for the LCR that discuss the need to collect samples from homes that have experienced “typical residential water use during the day before the compliance sample is collected.” The second document is a report prepared to explain why we “invalidated” samples for excessive stagnation in Lansing. It was in the aftermath of this event when EPA eliminated the ability of state programs to invalidate sample results based on excessive stagnation that ed the Michigan Public Water Supply Program to develop a recommendation that communities advise residents participating in their compliance monitoring to flush the designated sampling tap 6 to 8 hours before sample collection (the night before in most cases) to ensure that this tap was not experiencing excessive periods of stagnation. We did not want subsequent regulatory requirements to be imposed based on water quality information that did not accurately reflect the regulatory intent. This briefing report also xxxEND_PAGE:deq04_b214_3461_3462_1 discusses the fact that the regulatory monitoring scheme was not intended to represent human intake, but was based upon sampling a statistically significant number of residences containing leaded plumbing materials as a measure of successful water treatment efficacy. xxxEND_PAGE:deq04_b214_3461_3462_2

RE: DHHS Complaint Number? - RE: environmental complaint filed on Oct. 8

The mystery is solved! I’m covering Executive Division’s main phone line this morning, and | received a call from Wayne Koper (a citizen from the Thumb area) who said he faxed to 373-1610 an Environmental Incident Report Form (a DAG form) regarding “poisoning of children of Flint.” He said the complaint number assigned to it is: 2015-ep10081942753-A. | checked online and found out that fax number is for the DAG’s Environment, Natural Resources, and Agriculture Division. | then spoke with Peter Manning’s secretary, Nancy Hart, to see if they received his form and to let her know I’d be e-mailing her a phone message from Mr. Koper to return his call. She said they have the form, and she will ask Peter if it's OK to forward a copy to me to share with you. Stay tuned.....

University of Michigan inquiry re: Flint

Date: Thursday, August 06, 2015 11:52:00 AM Yesterday, Steve Busch and | participated in a conference call with Professors Lutgarde Raskin and Krista Wigginton (Dept. of Civil and Environmental Engineering) and Prof. Stuart Batterman (School of Public Health) and several of their graduate students. They wanted to discuss recent events in Flint and are interested in possibly providing sampling, analysis, and education/outreach to address potential lead exposure issues, TTHM issues, possibly microbial activity and/or aesthetic problems. They are aware of the report published on the ACLU website identifying lead as an issue in Flint and were interested in helping to obtain analytical data to determine the potential extent of the problem and to help residents understand what it means for them. We suggested they begin by having discussions with the City to determine what level of assistance might be helpful to the City. If this moves forward, we would recommend that DEQ, DHHS staff, LHD staff, and a group of local residents/stakeholders be included in discussions to guide future activities. Today, Steve provided UM with contacts at the City. UM is interested in quickly arranging a preliminary meeting to flesh out what might happen going forward. We'll keep you updated if this progresses. Liane Liane J.
