Toledo, Ohio, had to turn off its drinking water supply recently. Toxins produced by algae, which are in turn produced by farm runoff into Lake Erie, the source of the Toledo area's water, threatened public health.
It begs the proverbial question: Can it happen here, in Wisconsin? Probably not. But that doesn't mean Wisconsin's waters are free of toxic algae blooms.
