Mining Pollution Legacy and Clean-Up

First published May 21, 2017

In the mid-1850’s hydraulic mining filled the stream channels and muddied the waters all the way down to the Pacific Ocean.

Mercury was used in sluice boxes to amalgamate gold. “It is estimated that ten million pounds of mercury were lost into the streams,” comments Kyle Leach, Geologist for Sierra Streams Institute.

“The tale of the Gold Rush is a greedy tale,” says Shelly Covert, Nisenan Tribal Council Secretary. “Miners came for the land and for the gold. All of the trees, waterways, fish, and plants that  our families lived on were gone.”
