WEXFORD COUNTY, Mich., (WPBN/WGTU) -- A body of water in Wexford has consistently tested high for E. coli over the years.
Because of this, District Health Department #10 and the Michigan Department of Environment, Great Lakes, and Energy requested help from Ferris State University researchers.
"People can’t be bathing in E.coli without having problems with their health," said Ferris State University Biological Sciences Professor and Director of the Shimadzu Core Laboratory Sky Pike. "It was very high, I mean dangerously high.”
Lingering poor water quality proving the be problematic in Billings Lake.
“The beach is usually closed I would say two to five times per summer,” said Pike.
To try and solve the issue, a multi-year collaboration was formed between Michigan universities and government laboratories.
Ethan Tippett is a senior in the biotechnology program at FSU and is helping with these studies
We travel up to billings lake once a week for 14 weeks during the summer and also after any rain events within the past 24 hours we sample," said Tippett. "I want to say there were about 150 total samples.”
The U.S. Environmental Protection Agency is also linked to this research.
They've developed what is called a Q-PCR Testing method - technology used for measuring DNA in bacteria.
“With this new method, we are able to determine the same day if that E. coli level is higher or not. We don't have to wait 24 hours. We can get the results within 8 to 12 hours," now the beach can be closed immediately, on the same day rather than waiting the next day," said Pike.
Researchers found a link between rain events and E. coli levels and this creek is contributing to the problem.
“We think that is what is causing the elevations of E. coli in the lake at this point," said Pike.
But the mystery still remains, what is it coming from?
“Could it be from humans could it be from dogs, could it be the geese, that are here? It could be a leak in the sewer system we are not sure about that yet," said Pike.
Through the Q-PCR testing, they will eventually be able to determine the source.
"We're currently in the process of working out the microbial source tracking and getting to develop the method that works best with technology,” said Tippett.
A step closer toward finding a solution in Wexford County.
knowing we can make an impact and prevent people from getting sick as much during the summer makes me happy and puts in perspec
