Selenium is a vital nutrient for humans. I have been told by a doctor to eat more of it. In some concentrations it may be poisonous to fish.

On the other hand 6 of 6 Simplot plants are exceeding the EPA limits for selenium emissions. That is probably six different rivers or at least 6 separate regions on rivers.
