Coal mines, selenium and their legacy for aquatic environments


Recommended Posts

Thanks for the link. That was a really informative read that covers all sides of the dliemma. I am now more educated on the fact that selenium is a natural contaniment in the huge waste rock piles left from the digging that leeches into the environment when exposed to rain and snow. No quick or easy solution

This is the issue....so much disturbance, and there is no way to collect all the runoff from snow melt/rain events.

The amount of water that will get treated (with limited success)  in comparison to all the runoff is insignificant. Therefore we are left with a giant, ever-increasing problem of Selenium accumulation that will continue for centuries.

Is the benefit of making steel with a cheap heating fuel greater than a legacy of selenium pollution?

There is already technology available for making steel that does not use metallurgic coal....it just costs a bit more. 

We are not making any new mountains or rivers.

The value of clean water is only going to go up as this messy planet ages
