Yes. Along many fishing shorelines there are signs posted that tell you how many of each type of fish you can eat per week, depending if you are a man, woman, depending on age range.
Each state publishes them. Here is the one for Minnesota for example:
"They also take into account findings of low levels of Perfluorooctane Sulfonate (PFOS) in fish throughout Minnesota."
So I'm not sure how you could make a statement like "Eating a fish meal out of the Mississippi in Minnesota (by 3M) will give you a month's worth of PFOS if you were just drinking contaminated tap water."
