Why water in many Alaska’s rivers is turning orange – Times of India


NEW DELHI: Thawing permafrost in Alaska is transforming some of the state’s clear waters into a murky, rusty orange hue. As the frozen layer of soil melts, minerals become exposed and seep into the water, according to a study published on May 20 in the journal Nature Communications: Earth and Environment.
“The more we flew around, we started noticing more and more orange rivers and streams,” said study co-author and National Park Service ecologist Jon O’Donnell.“There are certain sites that look almost like a milky orange juice. Those orange streams can be problematic both in terms of being toxic but might also prevent migration of fish to spawning areas.”
Permafrost, which is rock or soil containing ice that remains frozen for two or more years, covers about 80 percent of the ground in Alaska. The state is warming two to three times faster than the global average, causing significant thawing of permafrost, a report in Popular Science said.
As ice-filled permafrost begins to thaw, it can turn into mud that cannot support the weight of the soil or vegetation above it. This can lead to damage to human-built infrastructure including buildings, homes, pipes, and roads. Thawing permafrost can also expose organic matter, including the remains of dead plants, which release methane and carbon dioxide into the atmosphere. Additionally, long-dead viruses or bacteria that could potentially threaten human health may be released.
Visible from space
In 2018, O’Donnell first noticed a river that appeared rusty, despite being clear the year before. To investigate further, O’Donnell and the research team documented and sampled some of the impaired waters. They examined 75 locations across northern Alaska’s Brooks Range, an area about the size of Texas.
“The stained rivers are so big we can see them from space,” said study co-author and University of California, Davis geochemist Brett Poulin. “These have to be stained a lot to pick them up from space.”
Poulin observed that the staining in the water appeared similar to what happens during acid mine drainage. However, there were no mines near the impaired rivers, which include the Salmon River and other federally protected waters.
Chemical changes
The researchers hypothesize that as the permafrost melts, the minerals stored inside the frozen ground are released. Metal ores that were once locked up are then exposed to water and oxygen, releasing acid and metals into the river.
“Chemistry tells us minerals are weathering,” Poulin explained. “Understanding what’s in the water is a fingerprint as to what occurred.”
Initial samples collected in June and July 2023 showed some waters had a pH of 2.3, while the average pH for these rivers is 8. This indicates that sulfide materials are weathering and making the water more acidic. The researchers also found elevated levels of iron, zinc, nickel, copper, and cadmium. “One of the most dominant metals is iron. That’s what is causing the color change,” noted UC Davis Ph.D. candidate Taylor Evinger.
Implications for ecosystems
The team is currently in the second year of a three-year grant aimed at understanding what is happening in the waters, determining what other areas could be at risk, and assessing what it means for fishing stocks and drinking water. The problem is growing, affecting habitat, water quality, and other ecological systems. It is degrading otherwise healthy habitats and could threaten the safety of drinking water in rural areas.
“There’s a lot of implications,” O’Donnell said. “As the climate continues to warm, we would expect permafrost to continue to thaw and so wherever there are these types of minerals, there’s potential for streams to be turning orange and becoming degraded in terms of water quality.”
More detailed work is needed to better understand the problem and to see if rivers and streams can rebound after colder weather restores permafrost. Satellite images dating back to 2008 show that the waters have been changing color for well over a decade and could only be growing over time.
“The issue is slowly propagating from small headwaters into bigger rivers over time,” O’Donnell said. “When emergent issues or threats come about, we need to be able to understand them.”

Alaska’s voter roll transfer: Republicans bash hearing questioning if lieutenant governor broke the law

Alaska’s voter roll transfer: Republicans bash hearing questioning if lieutenant governor broke the law


JUNEAU, Alaska (KTUU) – A legislative hearing into the legality of Alaska’s voter roll transfer to the federal government ended in partisan accusations Monday, with one Republican calling it a “set-up” and others saying it was unnecessary, while Democrats defended it as needed oversight.

“Andrew (Gray) and the committee has a bias. I mean, that much is obvious from watching it,” Rep. Kevin McCabe, R-Big Lake, told Alaska’s News Source walking out of the hearing before it gaveled out. “Most of the testimony was slanted against the state and against the federal government.”

The House State Affairs and Judiciary committees met jointly Monday to hear testimony about whether Dahlstrom violated the law when she transferred the entirety of Alaska’s voter rolls to the federal government.

Rep. Steve St. Clair, R-Wasilla, agreed with his Big Lake counterpart that the hearing was unnecessary.

“I think we’re speculating on what the intent of the DOJ is and I believe we need to wait and see,” he said.

Rep. Andrew Gray, D-Anchorage and chair of the House Judiciary Committee, pushed back when told of his Republican colleagues’ reaction.

“I think that I went above and beyond to try to include everybody,” Gray said as he left the meeting. “If people are saying that if the Obama administration had asked for the unredacted voter rolls from Alaska, that all these Republicans around here would have just been like, ‘oh, take it all. Take all of our information.’

“That is not true. That is absolutely not true,” Gray added.

Rep. Ted Eischeid, D-Anchorage, backed his House majority colleague, questioning whether Republicans would have preferred if the topic not be addressed at all.

“The minority folks on the committee had a chance to ask questions,” he said. “I think this is a meeting we needed to have. Alaskans have asked for it. I think there’s still a lot of unanswered questions. So shedding light on the state’s actions, that’s bias?”

Dahlstrom did not attend the hearing. Gray said she was invited multiple times but cited scheduling conflicts. The lieutenant governor oversees the Alaska Division of Elections under state law.

In her most recent public statement — published Feb. 25 on her gubernatorial campaign website, not through her official office — Dahlstrom defended the voter roll transfer, saying the agreement with the DOJ was “lawful, limited” and that Alaska retains full authority over its voter rolls.

“The DOJ cannot remove a single voter from our rolls,” she wrote. “Its role is limited to identifying potential issues, such as duplicate registrations or individuals who may have moved or passed away.”

Representatives from the state’s Department of Law and Division of Elections both testified in defense of Dahlstrom’s decision. Rachel Witty, the Department of Law’s director of legal services, told the committee the state viewed the DOJ’s purview.

“The DOJ’s enforcement authority is quite broad,” Witty said. “And so, we interpreted their request as being used to evaluate and enforce HAVA compliance.”

HAVA — the Help America Vote Act — is a federal law that sets election administration standards for states.

Lawmakers also heard from an assortment of outside witnesses who largely questioned the legality of Dahlstrom’s actions, including former Lt. Gov. Loren Leman, who served under Republican Gov. Frank Murkowski, and former Attorney General Bruce Botelho, who served under Democratic Gov. Tony Knowles.

The Documents: A Months-Long Timeline

As part of the hearing, the committee released months’ worth of documents between the Department of Justice — led by Attorney General Pam Bondi — and Dahlstrom’s office, detailing the effort to transfer Alaska’s voter rolls over to Washington.

The DOJ first asked Dahlstrom to release the voter rolls in July of last year, citing the 1993 National Voter Registration Act, which requires states to allow federal inspection of “official lists of eligible voters.”

Dahlstrom agreed to release the records in August, providing a list of voters designated as “inactive” and “non-citizens,” along with their voting records and the statewide voter registration list — but it did not include what the DOJ wanted.

“As the Attorney General requested, the electronic copy of the statewide [voter registration list] must contain all fields,” reads an email sent 10 days after Dahlstrom agreed to release the data, “including the registrant’s full name, date of birth, residential address, his or her state driver’s license number or the last four digits of the registrant’s social security number.”

Dahlstrom agreed to provide the full details months later, in December, citing a state statute that permits sharing confidential information with a federal agency if it uses “the information only for governmental purposes authorized under law.” Those purposes, she wrote in the email, are to “test, analyze and assess the State’s compliance with federal laws.”

“I attach some significance to the fact that it took the State … nearly four months to respond to the Department of Justice’s demand,” former AG Botelho told the committee.

That same day, Dahlstrom, Alaska Division of Elections Director Carol Beecher and DOJ Assistant Attorney General Harmeet Dhillon signed a memorandum of understanding governing how the data could be accessed, used, and protected.

Dahlstrom’s office publicly announced the transfer nine days after the MOU was signed — nearly six months after the DOJ first made its request.

“Alaska is committed to the integrity of our elections and to complying with applicable law,” Dahlstrom said in the December statement. “Upon receiving the DOJ’s request, the Division of Elections, in consultation with the Department of Law, provided the voter registration list in accordance with federal requirements and state authority, while ensuring appropriate safeguards for sensitive information.”

A 10-page legal analysis from legislative counsel Andrew Dunmire, requested by House Majority Whip Rep. Zack Fields, D-Anchorage, concluded that the DOJ’s demand defied legal bounds.

“The DOJ’s request for state voter data is unprecedented,” Dunmire’s analysis states, adding that the legal justification the DOJ used to demand access to the data has never been applied this way before.

“Multiple states refused DOJ’s request, which has resulted in litigation that is now working its way through federal courts across the country,” he adds.

Alaska Air National Guard personnel conducted a rescue mission Saturday, Feb. 21, after receiving a request for assistance from the Alaska State Troopers through the Alaska Rescue Coordination Center.

The mission was initiated to recover an injured snowmachiner in the Cooper Landing area, approximately 60 air miles south of Joint Base Elmendorf-Richardson. The Alaska Air National Guard accepted the mission, located the individual, and transported them to Providence Alaska Medical Center in Anchorage for further medical care.

The mission marked the first search and rescue operation conducted by the 210th Rescue Squadron using the HH-60W Jolly Green II, the Air Force’s newest combat rescue helicopter, which is replacing the older HH-60G Pave Hawk. Guardian Angels assigned to the 212th Rescue Squadron were also aboard the aircraft and assisted in the recovery of the injured individual.

Good Samaritans, who were on the ground at the accident site, deployed a signal flare, that helped the helicopter crew visually locate the injured individual in the heavily wooded area.
Due to the mountainous terrain, dense tree cover, and deep snow in the area, the helicopter was unable to land near the patient. The aircrew conducted a hoist insertion and extraction of the Guardian Angels and the injured snowmachiner. The patient was extracted using a rescue strop and hoisted into the aircraft.

The Alaska Air National Guard routinely conducts search and rescue operations across the state in support of civil authorities, providing life-saving assistance in some of the most remote and challenging environments in the world.
