So, go to the source of one of these contaminated river tributaries, instal a centrifugal filter, take the resulting caked material to a testing laboratory. if the sample cake has enough rare Earth content; the rivers could be protected via aggressive centrifugal filtration, followed by processing of the cake for Rare Earth metals, the tailings from this processing will concentrate less valuable metals making secondary processing a possibility.

Climate change deniers be like "Water changing color is normal, humans are supposed to evolve to adapt to it". I would love to see how those crooks mutated to adapt to their own shit

Mt.shasta also has high levels of metal mostly aluminum from the chemicals they spray our skys with ,nearly everyday around the world, tennesee and new Hampshire are on the right path of banning chemical spraying in our sky, .i find it odd people dont look up and notice there capped in white ,and you can see the clouds .clouds are not brown ...period ,sad ,

China and the Asian countries have been doing this for 100 yrs.

I hope they make it!

Gold mine pollution

The comment section is completely the opposite of what should be going on with this video. Yikes

The earth has been doing this for all time changes

Don’t tell me global warming 😂 It’s a natural element get over it

Are volunteers needed? Past exp usgs, water board. Industrial waste insp. This really caught my attention….very familiar with in place treatment systems for metals and package plants…

Not just affecting aquatic organisms and humans, but all animals. Hate to see this. If Trump is elected, he will approve large scale copper mining on the very edge of the BWCA wilderness in Minnesota. That threatens a permanent pollution of the relatively pristine waters, and the drainage into Lake Superior. The well-being of nature depends on your vote.

Sounds like mining opportunity.

Excellent video and science! We observed the same phenomena here in the Yukon.....a small drainage called Cache Creek, part of the McQuesten River watershed...once a healthy stream, it shifted rapidly over a few years to a natural ARD impacted drainage by the early 2000s. There was no history or active mining within the Cache Creek watershed. In 2011 we attempted to document the source of the ARD as well as the cause of this shift and, although we could only speculate at the time, it was thought that the loss of permafrost in the upper reaches of the creek was the trigger that caused the dramatic shift in water quality. This allowed subsurface mineralized deposits (frozen for thousands of years) to become more susceptible to oxidation and ARD generation. It continues today....

It's called silt , the thawing of the permafrost can now mix causing coloring in the river

Your video is really very useful. But did you know that your video is not reaching your audience?

Well, you keep electing governments that promote NeoLiberal values. "Grow the economy" "good jobs"...

We don’t trust white man who speaks with two tongue 👅 and their broken treaties then and now and their masonic words……and they know what happened it ain’t no perma frost ok sure but most will believe(be-lie-ve)….but some not of true spirit and discernment and common sense and the truth is stranger than fiction

Bottle that and sell it as Glacier-fed Iron Water. With proper marketing someone could crush it.

YOU ARE ALL MISSING THE BIG PICTURE, THE IS A HUGE OPERTUENTY FOR NATURAL RESOURCE EXTRACTION, INCULDING MINING FOR NICKEL, COPPER, ZINC AND IRON! THE STATE WLL BE ABLE TO BUILD A 4 LANE DIVIDED HWY FROM ANCHORAGE TO THE NORTH COAST WHICH WOULD BE A GAME CHANGER FOR ALL BIG RIGS THAT TAKE THE VERY DANGEROUS JOURNEY EVERY WINTER! THE STATE AND PRIVATE PARTNERS CAN THEN START FRACKING FOR NATURAL GAS AND DRILLING FOR ETHICAL OIL AND TURN ALASKA INTO TEXAS 2.0! BECAUSE WE ALL NEED IT WEATHER YOU LIKE IT OR NOT! CANADA AND THE UNITED STATES ARE THE ONLY CONUTRIES WITH ELECTED GOVERNMENTS AND HAVE LARGE RESERVES OF OIL AND NATURAL GAS! ALL THE OTHER CONUTRIES THAT HAVE LARGE RESERVES ARE RUSSIA, NORTH AFRICA AND THE MIDDLE EAST WHICH ARE ALL RUN BY DICTATORS! WHEN THE WESTREN CONUTRIES AROUND THE WOURLD BUY OIL AND NATURAL GAS FROM THESE CONUTRIES IT FUNDS THER WAR CHEST THUS RESULTING IN COSTLY ARMED CONFLICTS!

You see this in the Chesapeake Bay as well. As matter of fact, along the shore line one can pickup rust colored climbs of clay mixed with iron. I think the bay was formed by an iron rich meteor that struck 80 million years ago. But I’m working off a fading memory here.

ALL WE HAD TO DO WAS RESPECT LIFE AND ENVIRONMENT? THE LIFE WE POISONED! CREATES THE OXYGEN AND IS THE BEGINNING OF FOOD CHAIN!

We’re doomed

Chissà cheii...ieii...buteii...nelegueii...

We are so doomed. It’s not because of earth just doing its normal thing…. It’s us that are dooming the planet thinking that we are so smart and that we understand the world better than Mother Nature does. Every spring this takes place. Every time there a big rain storm this takes place. Generally, people are just shit stupid and full of theirselves!!! A reset should happen, hopefully people with common sense survive .. if not, then so be it. The next sentinel being here can try again with their own form of intelligence……

Grade: A - . The video is too choppy - it is very distracting to change the scene or person speaking every few seconds. Ms Evinger and Mr Poulin are the only 2 people that were necessary to have speak. In spite of the disappointing editing and production, this video still gets an A- because it is virtually the only video on YT that has somebody (Mr Poulin) use the word "hypothesis" correctly and it is concise and presents clear information. I do give the editing and production team huge credit for not packing this video with fluff to make it longer (like most science videos on YT).

Fear mongers, alarmists, liars. Why not show us video footage of the headwaters to " any" of these waterways???

And the ones that are worried about and those that want to remove dams to save salmon are never going to see that come to fruition before the oceans food chain is stopped, then we start to die off quite rapidly.

Yet the MAGAts won’t believe any of this! There should be a study to figure out why so many people are just so effen stupid!

This is th future, and it's unfortunate we ended up here. There is no way back, alaskans will be walking in muck for decades, its over 😢

"aquatic, environment, and human health" let's stop separating ourselves from the environment. Yes it is semantics to a point, but we depend on the environment for our health.

What most people don’t realize, is that the big oil, gas, & mining industries actually want global warming to continue, because it is opening up access to mining & oil drilling in areas of the Arctic that were previously inaccessible due to permafrost & ice. Think about it - because of their insatiable greed, these ultra-wealthy people truly don’t give a damn about catastrophic global warming or environmental degradation.

Cycle of the planet, I'm sure this has happened before.

Here in America billionaires like the Koch and the Wilks will primary any GOP candidate who acknowledges climate change is real. The solution Alaska? Stop electing the GOP! This is NOT just an environmental issue, it's a political one.

Have to wonder if they're having similar problems in Russia.

So what happened about 8,000 years ago during the Holocene Optimum when temps were warmer?

Happens every Spring, LOL Also this is an old video and these people are not from Alaska. 23-24 had the most snow and ice buildup seen in many years

It looks like glacial silt. The world has not been warming since 1992. Arctic is warming with reason proving to be warm Atlantic Ocean water migrating deeper and more frequently into the Arctic Ocean warming it and the region.

Came to see the science aliterates deny reproducible findings, muse about their gut feelings and anecdotes, and was not disappointed.

This is so depressing.

Gold

As the Earth's Magnetic Field Weakens Further, and the Sun comes to the Peak of this Solar Cycle, you will see More Radiation In and Therefore, MORE MELTING. NATURAL PROCESS.🆗

THE NEW MEME STOCK IS 🎉🎉🎉🎉🎉LUCY🎉🎉🎉🎉

I live in Alaska and been here 60 years and this been going on for years . Yes glaciers are melting but guess what more are growing it is earth doing it's thing . Sorry it may be a issue but it is more about research wanting more money. I have met researchers they say the same thing need money.

OK, you got no business trying to make us believe that you know what you're talking about when you can't (or won't!) even pronounce the word "Arctic" correctly. Ignorance and incompetence.

BUNCH of BULL...🤣🤣🤣🤣🤣

Since climate change ills natural to the planet but seems to us as alarming, these are signs of change. With our magnetic poles changing and the magnetosphere weakening also we will need to stay vigilant to try and stay ahead of the game. Thanks for the paper!

Some of those rivers ran “muddy” every spring through much of the season. I lived in Alaska for 25 years and still return. I’m not disputing all of the findings, but I do believe it is being used to discourage mining and oil/gas exploration in the VAST areas that they m append out. There are some current operations in some of those areas already. Taking this video at face value is being very naive about the absolute ENORMOUS geographical regions they have indicated. And, of course, it is a PBS production.

you mean Alaska might be more livable soon?

Is there also GOLD?
