It’s so crazy because I’ve done a deep dive on this lately as I was going to stay at my friends house next spring on torch lake and travel the area and fish some of the nearby streams for brown trout steelhead salmon etc.
I got to thinking that I should fish torch lake even though he warned me that it was tough to fish. I looked it up and found out that people catch Atlantic salmon out of it. I noticed that there is a do not eat warning associated with that species because of high concentrations of mercury, PolyChlorinated Biphenyls (PCB’s), and dioxins. That is where the rabbit hole started…
From what I gather much of the state has high levels of PFAS in the river systems and they’ve gone about warning people many times not to eat the fish and have published species specific guides on consumption.
There’s a lot of ambiguity on what the safe levels are but I believe it was either the EPA or the state of Michigan declaring that 19 ppm was the high tolerance for drinking water. Some of the fish they have tested are showing up with HUNDERDS of thousands of ppm in them.
Apparently a bunch of the pollution is caused from all the manufacturing in the state and is also in Lake Michigan. The other major factor is the fact that the military constantly does drills using fire fighting foam which is loaded with PFAS. Some of the stuff I read says it’s contaminated groundwater up to 100 miles away from these bases.
3M Has been under fire for a long while about the pollution they manufacture and only just recently stopped producing PFAS.
Its been hard for me to discern between environmentalist pearl clutching and real deal environmental emergency. That said the whole point of my trip was that my son wanted to go camping in the wild and eat what we catch and I told him that we are going to find somewhere else to go..
