More than four year since the water system crisis began in Flint , Michigan , raw information extend to filter out . That the city ’s water was to a great extent contaminated with lead isno secretnow . Scheol , even deathly pneumonia - causing bacteriaaren’t a mystery . Dangerous fluorinated substances , though , are something that ’s sneak under the radio detection and ranging — until now .
The commonwealth ’s Department of Human Health and Services ( DDHS ) discovered the Flint River was have increase level of contamination from per- and polyfluoroalkyl substances , also know as PFAS , a year before the city of Flint switch to this river as its drinking water source in 2014 . This grouping of semisynthetic chemical has beenlinkedto cancer , hormone disturbance , obesity , and immune dysfunction .
Local newspaper The Flint Journal - MLivefounda long - forgottenreportthe section had published in 2015 citing water sample taken from the river in 2013 that contained levels of PFAS exceeding the state ’s drinking urine standards . It ’s unreadable whether anyone at the state level recall to inform anyone lick for the city of Flint , although a spokesperson for the DDHS told MLive the study was shared with other state agency and the Environmental Protection Agency . Still , it ’s potential if the PFAS egress had been easily communicated , the city would ’ve never switched to the Flint River as its drinking H2O source in 2014 — the move that ultimately have the ruinous health crisis in the predominantly pitch-black city of almost 100,000 .
The water samples in the river reached PFAS levels of 87.2 and 72.1 parts per trillion . The Environmental Protection Agency’sfederal action limitis 70 section per trillion , but a report the White House and EPA seek to keep from going publicsuggeststhat number should be close to 12 part per trillion .
“ Anything above [ the federal military action level ] is of fear , ” tell Lois Wolfson , a senior medical specialist at Michigan State University Extension , to Earther .
In an email to Earther , a representative for the DDHS downplayed the meaning of the written report ’s finding .
“ The 2013 surface water tests for PFOS in the Flint River simply do n’t transform into any evidence of a PFOS exceedance [ sic ] in Flint ’s drinking water during the period of business organization , ” the spokesperson told Earther , add together that there is “ no evidence ” that drink water ever exceeded the EPA health advisory of 70 parts per trillion . EPA result for “ finished drink water ” in October 2014 — after the switch to the Flint River had been made — were “ non - detect ” for PFOS and PFOA , the two most widely produced PFAS , the representative stay on .
Finally , the land remark that the EPA ’s Union action mechanism stratum of 70 ppt for PFAS was not countersink until 2016 , and that the surface water grade from 2013 were “ below the current consultive levels at the time the report was issued . ”
PFAS do n’t burst down , and they can move far distances once they reach open water supply , Wolfson explained . So the source of the Flint River ’s contamination remain a mystery . Could nonstick cooking utensil be to blame ? Maybe . former firefighting foam ? Perhaps . A Brobdingnagian array of consumer products — from microwaveable popcorn to carpets and fabrics — have used the chemicals since they became pop in the 1940s .

Michigan is seeing PFAS show up seemingly everywhere : More than 1.5 million people throughout the state have beenexposedto the chemical in their drunkenness water , allot to the Department of Environmental Quality . Roughly 30 H2O arrangement , including those that provide Grand Rapids and Ann Arbor , are facing this result .
“ Flint ’s not the only place , ” Wolfson separate Earther . “ It ’s probably prevalent in other State Department , as well , but Michigan is doing a surveillance to those shoes that might be more prostrate to contaminant . ”
await like the state take its deterrent example from Flint and is trying to debar another water crisis .
