Flint Water

Technical Advisory Team, lam pleased to report that the City of Flint has officially returned to compliance with the Michigan Safe Drinking Water Act and we have received confirming documentation from the DEQ today. The GAC filtering was installed on time and was instrumental in our ability to maintain an average level under the MCL. We anticipate that we will have no further notices going out. Recent testing has raised questions regarding the amount of lead that is being found in the water and I wanted to report to you our current status. At the onset of our plant design, optimization for lead was addressed and discussed with the engineering firm and with the DEQ. It was determined that having more data was advisable prior to the commitment of a specific optimization method. Most chemicals used in this process are phosphate based and phosphate can be a "food" for bacteria. We have performed over one hundred and sixty lead tests throughout the city since switching over to the Flint River and remain within the EPA standards. We are currently designing an optimization plan with the engineering firm that will be presented to the DEQ and upon approval we expect to have it implemented by January 2016. It is worthwhile to note that the DEQ has reported that other cities have taken years to complete an optimization plan and we anticipate having a plan in place over the next four months. 1 xxxEND_PAGE:deq18_b127_1239_1240_1 It is also worth noting to this group that there are different lead testing methods used within industry and the city remains consistent with the most recent EPA approved testing method which can produce different results than other methods. We hope to schedule another TAC team meeting for late September or early October, I will attempt to keep everyone informed and look for the best dates. We are inviting additional EPA experts to become a part of this committee. Thank you, Howard Croft Public Works Director City of Flint 1101 S.

Water Quality Update

Technical Team, | am writing to provide you an update on the City's ongoing plan to improve the water quality in the City of Flint. This morning, the U of M Flint announced that recent testing showed 48M levels slightly above the : in two of its buildings. The City responded to this recent information of concern with increased flushing in the area where subsequent internal tests have shown the levels to have subsided to under than 80 B86. The ‘Ff 84 level leaving the water plant is currently in the 45 -55 #6 range and in areas with minimal circulation the level can rise by the time it reaches a tap. The installation of new filter media at the water plant which is designed to greatly reduce the EE HV level in the plant is ahead of schedule and is expected to be installed by mid-July. The DEO has approved the design and actual testing by the vendor over the past two weeks has veriieg that the selected media should work. This is expected to have an immediate impact In addition to the filter installation, we have engaged in increased valve exercising over the last two months and have checked over half of the 7,000 valves in the system. The valve turning has a tendency to result in temporary water discoloration but increases the overall water circulation and identifies areas where valves are inoperable. Our annual Consumer Confidence Report will be distributed in early July and will contain significant information about the water system. We will also include the notice of our recent quarterly testing in 1 xxxEND_PAGE:deq16_b5_0892_4900_0241 sostoasrate which all eight sites were verified to be under the MG but the running average at one site required a notice to be sent. | will email everyone when we schedule the next The team meeting which we have currently targeted for mid-August.
