State officials will continue to test a long contaminated site in Jackson when PFAS's chemicals are now declared in the Grand River.
Test samples taken from January 18 from 12 different locations at and across the former Michner Plating show high levels of poly-fluorine compounds at 12 sites.
PFAS got an ex-corrupted factory in Jackson
The highest reading reached 6,952 cod per trillion (ppt) on the northwest edge of the property at 520 N. Mechanic, west of Chooper and Ganson in central Jackson. The boundaries of the former Grand River factory, with the largest river of Michigan at 260 miles long.
Five surface water tests for both PFOA and PFOS yielded the two types of chemicals that clean up lakes and rivers clean up in Michigan.
However, the overall total number in the Grand River was 1,759- to 2,019-ppt, according to data from the Environmental Quality Department. This includes both sites per hour and river, raising issues about the basis of corruption.
It can also raise questions about what happens when the PFAS spectrum is detected in the surface surface water of the state. The combined results of PFAS show a combination of all 24 compounds in the state test line. Of those, not only PFOA and PFOS prompt activity by the Environmental Quality Department, and 22 do not meet cleaning standards.
The initial focus describes what is near the site and what it spreads.
"The DEQ through its Water Resources Division is planning to carry out some water sampling in 2019 in the Grand River to track the source or sources of the PFAS," said Don Hayduk, environmental health director for County Jackson County Department.
So far, Hayduk said, the abandoned factory is the only active PFAS investigation in the Jackson area. State drinking water tests in Jackson show that the chemicals were not found in 37 of 39 public sources; A level of 3-ppt was received in the other two. This compares with the long-term health advice of 70-ppt that issued the EPA.
Across Michigan, a wide-ranging test showed that drinking water has at least 1.5 million people with some type of poly-fluorine compounds. At the same time, the state continues to identify sources where the chemicals have surface water flowing that can affect drinking water supplies.
"While the DEQ does not believe that contamination is affecting any current drinking water aquifer, we are continuing to review records and we are talking to others," according to the state.
Municipal water systems have nearby properties, but both residential wells are used against restrictions and outside the water system boundaries.
The situation in Jackson poses some parallel to the investigation of PFAS in the Huron River, Hayduk said. In that case, it was found that a factory in Wixom was launching PFOS into the wastewater treatment.
Businesses releasing PFAS into Michigan waterways
One big challenge, Hayduk said: "The levels are much lower."
The Michner has pollution found in different places, including groundwater. Among the recent combined results, between 4,000- and 5,000-ppt – three received water in the underwater basement of abandoned buildings that went through pre-registration of tax and the state is now under control.
Test results from the basements include a range of PFOS from 2,400- to 2,800-ppt. So much PFOS shows at least 200 times the amount of the chemical allowed in surface water.
The corruption of the property was quite extensive that the Environmental Protection Agency had introduced to make emergency cleanups in 2015. Later, DEQ spokeswoman said that there is no active cessation.
But state officials will no longer evaluate the site, for PFAS and other chemicals with anxiety, as well as determining whether there are chemicals traveling from the site to nearby buildings.
"The focus of our current investigation is the volatilization to an indoor air path that determines the potential that mild soil / soil soil can migrate off-site that may cause exposure," according to the state.
Out-of-site sampling will begin in March, the state said.
