There are only a few ways the mercury could have gotten into the lake system. For one, it could have been dumped there. If mercury was on the land surface runoff from rain events could have washed it into the lakes. A third and less likely explanation is that mercury emitted from smoke stacks could have combined with water particles and precipitated over the lakes and surrounding land.

It would not have been able to be carried through groundwater as mercury is an immobile chemical and once in the groundwater it adheres to soil particles and does not travel far.
