Saving the Bay – The Aftermath of the Gold Rush: Mining and Mercury in San Francisco Bay
Beginning with the Gold Rush era, the legacy of mining activity in California remains in water systems today. Hydraulic mining practices caused massive amounts of sediment and mercury to enter the vast network of streams and rivers that feed into San Francisco Bay. Mercury continues to pollute the watershed, making many fish toxic to consume.

So the San Francisco bay has been contaminated with mercury from the cinnabar in the local hills for 100,000 years yet you only point out that the miners used mercury from 1860 to 1874 so the miners must be the cause of all the mercury in San Francisco pay. LOL!
70% of mercury found in fish in the ocean comes from natural sources of which Volcanic vents are the largest source. Man only contributes 40% of the mercury found in fish.
Why don’t you mention this in your report?
fucking it all up dumb fucks
I don’t think people necessarily believe that, but it’s true that Cancer rates are higher as a result in this area, and because of the Silicon Valley electronics industry leaching chemicals. So Mercury, and the chemicals from electronics manufacturing both get into the ground water table/aquafers.
Mercury or not, I wouldn’t eat anything that came out of that Bay…
This is the power of softness , water, it can break solid rock into aparts
Who else is here because of school?
So your saying mercury gets in the rivers naturally from cinabar in the ground.
I reckon there will always be people who make a show of indignant public outcry over other people’s blood, sweat, tears, hard work, creativity, learning, ingenuity, and achievement. Way easier to do that than actually studying, learning and creating a revolutionary process themselves. Glorifying the former at the expense of the latter may not be a good thing in the long run.
Scary…
Regardless of the past, the massive increase in population and increased demand for water in the area required man made changes in the waterways. It’s not like the virgin waterways could naturally have kept up with the demands placed upon it. As such don’t blame the past miners for the effects of ever increasing demands.
is there anyone else that has to watch this for school?
Excellent video!
What a crock of BS! You loons really believe mercury is killing people daily don’t you. If it was really happening it would be all over the news. IT’S NOT HAPPENING!!!!!!! You enviro WACKO"S will say anything to scare the uneducated into swallowing your own personal demented beliefs.
If it cant be mined it has to be grown. Be quite.
Miners today clean Mercury out of the rivers, support them
Love the sf bay
ass holes let us dredge the rivers to clean it up you cant have it al your way
One of the most insidious effects of mercury poisoning is mental deterioration, perhaps exhibited by someone we know.
i like because it tells about what the gold rush is like
Watching this in 2021, I have a question. Are the materials still spreading, because it’s been almost 11 years since you posted this.
