While visiting Parchment, where high levels of PFAS forced 3,100 people to drink bottled water, the governor said it’s "premature" to determine if the health advisory should drop.
Sunday, Snyder visited one of several sites where the city of Kalamazoo is connecting its water system to Parchment to bring residents to clean drinking water in the near future.
Contamination was found in Parchment as part of a statewide testing initiative Snyder launched by in 2017, which is discovering the toxic compounds in water supplies across Michigan.
Snyder was not in Michigan to declare the July 29 state of emergency, so Lt. Gov.
Two rounds of DEQ tests showed highly contaminated water entering the municipal water system from three source wells.
The latest test showed one well was contaminated with PFOS and PFOA, two PFAS compounds, at levels more than 26 times greater than the EPA health advisory.
Officials see it as a possible source of the PFAS contamination.
Dean said there are other industrial sites are being considered possible sources.
State officials are still working to determine how long the drinking water may have been contaminated.
Last week, results of tests at 15 water pumping stations serving the Kalamazoo municipal drinking water system found between 2 parts per trillion and 19 ppt of PFOS and PFOA in three stations.
