When I think of mining, the first thing that comes to mind is the classic gold rush miners from the mid-1800s. Someone that looks a lot like Stinky Pete from Toy Story 2. I don’t mean to imply that this is, or isn’t, what a miner looks like. However, this does say something about the general lack of thought about mining practices. The EPA certainly isn’t as ignorant about mines as I am; in fact, as of 2014, they had designated over 1,300 sites around the country as superfund sites requiring extensive cleanup efforts. Tullia Upton is also thinking about mines much more deeply than the average person, and she is uncovering some alarming information.
During a road trip through southern Oregon, Tullia was bummed when she was told it was unsafe to swim in a local river, so she decided to dive a bit deeper, figuratively of course. She learned that this area has become dangerously polluted due to waste products of the Formosa mine.
Mining practices involve extensive digging and extracting of heavy metals which are normally buried in a reducing environment deep down within the earth’s sediment. The process of digging up these heavy metals leaves behind a staggering amount of unused material, known as tailings. Mining also exposes the metals to oxygen and allows them to leach into soils and the watershed. Due to runoff from the tailings and other waste at the Formosa mine, there is now an estimated 18 mile dead zone where no organism can live. The full extent of the damage being done to the local watershed has not been thoroughly mapped though.
As she learned more about the dangerous metals coming from the mine, Tullia immediately got involved as a volunteer and secured research funding to study the pollution occurring at the Formosa mine. Tullia hopes to map the full extent of runoff from the Formosa mine and provide a better picture of the mess for the EPA, and other scientists, working on the cleanup process. When she finishes her Ph.D. here in Environmental Sciences, Tullia hopes to move on to a post-doc and eventually run her own research lab.
Tune in this Sunday, October 9th at 7pm PST to hear more about mine pollution and Tullia’s unique journey to grad school at OSU.
