![]() ![]() April 26 - EGLE received results for the fish collected from the Holloway and Mott reservoirs that showed elevated levels of PFAS.Three samples were collected two samples were above 70 ppt PFOA+PFOS. In November 2016, RACER Trust conducted an initial investigation of groundwater monitoring wells at the Coldwater Road Landfill due to historic operations of chrome plating at the site. ![]() The results for the samples collected at Carpenter Road and M-15 were 14 ppt and 16 ppt, respectively, below the EPA lifetime health advisory level of 70 ppt PFOA + PFOS. The results showed consistent levels above the WQS of 12 ppt PFOS in the Flint River and indicated a source was upstream of Holloway Dam. August 24 - EGLE received the surface water results for samples collected from the Flint River watershed in July 2018.July 11 - EGLE collected fish from the Mott Reservoir to be analyzed for PFAS in 2017.As part of this effort, EGLE collected samples at Carpenter Road and M-15, upstream of the city of Flint's drinking water intake. July 6 - EGLE collected samples from the Flint River and significant tributaries in the vicinity ofįlint.May 24 - EGLE collected fish from Holloway Reservoir to be analyzed for PFAS in 2017.EGLE developed a plan for additional sampling along the Flint River, including a location on the North Branch of the Flint River and locations on the South Branch both upstream and downstream of the Lapeer Wastewater Treatment Plant (WWTP).Sampling focused on the Flint River and major tributaries in the immediate vicinity of the city of Flint. A surface water sampling plan was developed to determine contamination sources along the Flint River for implementation in 2016.(There was no data to indicate contamination extended further upstream.) The advisory extended from the Flint River downstream of Mott Dam. Spring 2015 - The Eat Safe Fish guidance was updated due to PFOS in fish.In addition, the three Flint River species sampled had higher levels of PFOS than those species collected elsewhere from the river. PFOS levels exceeded DHHS's screening values, indicating a fish consumption advisory was needed. August 18, 2014, to SeptemFinal results for fish collected from the Flint River near Montrose were received.The State has no information to suggest that the concentrations in the river or drinking water supply exceeded the drinking water action level. Between April 2014 and October 2015, the city of Flint temporarily drew drinking water from the Flint River.October 31 - EGLE collected fish from the Flint River near Montrose to be analyzed for PFAS.The surface water samples were collected downstream of Flint's drinking water intakes, and the results were below the 70 ppt combined PFOS and PFOA EPA advisory level for drinking water. The exception was the Flint River where the 2013 PFOS concentration was over 3 times higher than measured in 2001. Concentrations of PFOS in river water samples were lower at nearly all of the sites sampled in 2013 compared to concentrations in samples collected at the same sites in 2001. August 19 - EGLE received PFAS results for the follow up surface water samples collected statewide, including those collected from the Flint River.August 9 - EGLE collected surface water samples from the Flint River.These municipalities will be continuing to evaluate and reduce sources of PFOS and PFOA, as well as consider local PFAS regulatory options. Work under the Industrial Pretreatment Program (IPP) PFAS Initiative will continue for the Flint WWTP, Genesee County Ragnone WWTP, and the Lapeer WWTP.EGLE will continue to monitor PFAS in fish from the Holloway Reservoir in 2021.EGLE will conduct the POCIS study in 2021 to monitor PFAS trends in the Flint River watershed.EGLE is awaiting the PFAS results for fish collected from the Holloway Reservoir and the south branch of the Flint River in 2020.For latest test results, contact the Great Lakes Water Authority directly. The city of Flint currently obtains its drinking water from the Great Lakes Water Authority, which was tested in November 2017 and found not to have detectable levels of PFAS. The discovery of the elevated concentrations of PFAS in the Flint River has led to numerous investigations of potential sources and mitigation efforts, including Gilkey Creek and Lapeer Plating and Plastics. In 2013 the Department of Environmental Quality (DEQ, now EGLE) detected PFAS in samples from the Flint River. The watershed is more than 1,300 square miles and consists of hundreds of tributary creeks, lakes, and the Flint River proper. The Flint River drains portions of seven counties in mid-Michigan. ![]()
