short version:
In the mid 1800’s during the late gold rush, miners blasted water (hydraulic mining) to try and find gold. It caused 1 billion yards of silt to fill the delta.
California miners from 1860 to 1900 used an estimated
10 million pounds of Mercury as part of their refining
process. Most of it was released into the water and air.
This Mercury is in our soil, streams and rivers. It works
it’s way up our food chain and can be hazardous to our
health. It’s good to be aware of the dangers of eating
fish or other wildlife that have higher percentages of
Mercury in them.
