November MOR

Mike, Attached is the November 2015 MOR and Enhanced Water Quality Monitoring Data. I have also attached the results of the verification of LCR monitoring sites in a digital format that the service center put together. The data on the LCR sites is lacking, but in talking with Mr. Bincsik at the service center, we may be able to to track some of the information via inspection of hydrants and dates they were installed to correlate the probability of a lead service line. It may be beneficial for the three of us to discuss this option before the holidays. Sincerely, Mike Glasgow Utilities Administrator City of Flint 1101 S.

Installation of Corrosion Control Treatment

Date: Wednesday, November 04, 2015 12:55:04 PM Michael, Please notify our department regarding the anticipated timeframe to install the corrosion control treatment system at the water treatment plant. The timeframe should take into account estimated time to receive the chemical feed pumps, storage equipment, and the orthophosphate compound. Coordination of the contractor to install the equipment also needs to be included. If there any delays with the installation of the corrosion control treatment system, please notify us as soon as possible. Finally, please inform us when the corrosion control treatment system is installed. If this occurs by next Monday, | may take the opportunity to conduct an inspection prior to our 12pm meeting.

Newall St. Date Sampled: 3/2/15 Thank you for participating in the lead and copper monitoring of drinking water. The levels of lead and copper found at your location are in the table below. Contaminant MCLG Your Result Key to Table Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements that a water system must follow. Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety. ppb: parts per billion or micrograms per liter. 1300 1300 Not Detected Lead can cause serious health problems if too much enters your body from drinking water or other sources, It can cause damage to the brain and kidneys, and it can interfere with the production of red biood cells that carry oxygen to all parts of your body. The greatest risk of lead exposure is to infants, young children, and pregnant women. Scientists have linked the effects of lead on the brain with lowered !Q in children. Adults with kidney problems and high blood pressure can be affected by low levels of lead more than healthy adults. Lead is stored in the bones, and it can be released later in life. During pregnancy, the child receives lead from the mother's bones, which may affect brain development. To reduce exposure to lead in drinking water: « Run your water to flush out lead. Run the water until it becomes cold. Use cold water for cooking and preparing baby formula. Do not cook with or drink water from the hot water tap; lead dissolves more easily in hot water. « Do not boil water to remove lead. Boiling water will not reduce lead levels. * Look for alternative sources or treatment of water. tf your lead result is above 15 ppb, you may want to consider purchasing bottled water or a water filter. Read the package to be sure the filter is approved to reduce lead or contact NSF International at 800-NSF-8010, or www.nsf.org for information on performance standards for water filters. ‘ — Identify if your plumbing fixtures contain lead. New faucets, fittings, and valves, may contain up to 8 percent lead including those advertised or labeled as “lead-free” and may contribute lead to drinking water. Consumers. should be aware of this when choosing fixtures and take appropriate precautions. Although the primary sources of lead exposure for most children are deteriorating lead-based paint, lead- contaminated dust, and fead-contaminated soil, the U.S. EPA estimates that 10 to 20 percent of human exposure to lead may came from drinking water. For more information, contact us at: i ter Plant a For more information on reducing lead exposure around your home and the health effects of lead, visit the U.S. EPA's Web site at www.epa.govilead, call the National Lead Information Center at 800-424-LEAD, or contact your health care provider, Certification: WSS: 2St6 | certify that this public water supply has provided the consumer nolice of lead result to persons served at each of the laps that was tested, elther by mail or by another od approved by ihe DEQ, within 30 days of knowing the result.

Steve & Mike, Good morning, I hope you enjoyed your holiday weekend. I am contacting you on behalf of Howard to request a "quote". Howard is preparing a presentation for the City Council on Monday night in regards to this recent lead & copper news. He would appreciate a statement in regards to why corrosion control was not required by the City at the onset of using the Flint River, and how it took two rounds of lead & copper sampling to determine that "optimization" is required. I have explained to him my understanding, although for the presentation he is looking for a brief statement of a couple sentences to reference or quote one of you.

May 2015 MOR

Mike, Here is a copy of the May MOR. A hard copy will go out in the mail today, but I like to get you a copy as soon as itis complete. I am still compiling the pool of samples for lead & copper monitoring. I had spoke with Adam a month or so ago about this same topic. I was planning on using the addresses where bottles were sent in the first round (2014). The hundred for which we have results is easy, it is the others that never returned the samples that is taking some time. FYI - The CCR for Detroit water is complete and headed to the printer this week. Still developing the one for Flint water, but we will be using the same company and since the mailing list is the same, we could still make the July 1st deadline.

Re: Lead-Copper info

Mike, To answer your questions: 1. I'm trying to compile the list. ere were a couple of Apartment residences that were used in the first sampling pool. These would be tier the majority were Tier 1. 3. A copy of the consumer notice is attached below. 4, This was in response to a customer complaint, and it is a business, I would only use the Utility sink as a site if we are short a sample, and would be a Tier 3. This is not in our sample pool, but is served by lead service line.

Mike, Here is a portion of our monthly MOR. The chemical feed rates are missing due to a computer glitch. J should have the completed copy of the report Monday, which I will email to you and also send a copy in the mail.

Flint MORs

Mike, Brent | was looking at Flint’s MORs and | just noticed that ozone treatment parameters (ozone dosage and residuals) are not included. Ozone treatment parameters need to be included in the MOR. Please include this in future MORs. Also, if you can resurrect the ozone treatment parameters from previous months of operation (since going to the Flint River)......we would like that information to include in the previous MORs.
