West Virginia's waterway 'reclamation' yields cleaner water, rare earth metals and a growing outdoor industry

Coal mines left waterways across West Virginia polluted by sulfuric acid and metals, but that’s not the end of their story. "Set on a quiet hillside, a series of cascading ponds are doing their small part to fix a big problem," reports Mira Rojanasakul of The New York Times. The three-pond system slowly "reclaims" the state's waterways for wildlife and people to enjoy once again, and it comes with a side benefit of rare earth elements.

The three-pond system works to reduce water acid and then remove metals. The first pond allows water to "percolate through limestone and organic matter," Rojanasakul explains. The second pond completes more filtration, allowing the aluminum to drop out. By the time the water flows from the third pond, the iron has dropped out. "Fish and sensitive species like salamanders and frogs are returning to Deckers Creek, which for decades flowed rust-orange and lifeless from iron and other pollution."

Deckers Creeks is "one of dozens of cleanup sites being installed across West Virginia, helping the state make progress on a global environmental issue: waterways poisoned from coal mining," Rojanasakul reports. "A few miles downstream, a new, higher-tech version of this cleanup process is yielding an unexpected bonus: 'Rare earth' elements, essential for clean energy technologies and military equipment, are being recovered from the pollution."

Decreasing water acidity and removing metals isn’t just helpful for wildlife and biodiversity -- acid mine drainage "can corrode pipes and threaten drinking water for many residents of rural West Virginia who rely on backyard wells," Rojanasakul writes. 

Federal and state officials help guide West Virginia's waterway reclamation efforts, but the "boots on the ground" are often small nonprofits. Rojanasakul adds, "They monitor sprawling watersheds and build relationships within communities, even talking private landowners into opening up their backyards for cleanup work."

Many locals view their reclaimed waterways as a potential path to a new revenue source for residents and the state. Rojanasakul reports, "Employment in the state’s outdoor recreation economy is starting to rival other industries, with 20,300 jobs in 2023 compared with 17,700 workers in mining and support activities that same year."

Quick hits: Super Bowl food line-up; heavy metal plants; immigration explained; changing U.S. geographical names

Super Bowl game parties are all about sporting fun served with delightful spreads of game-night food. "The Super Bowl is more than the championship game for professional football teams in the U.S. Super Bowl Sunday is the country’s 'second-largest food consumption day' (right after Thanksgiving)," reports CaLea Johnson for Mental Floss. "But which foods and desserts do Americans love most for the event?" Researchers mapped the answers state-by-state.

With China in control of much of the world's critical minerals and recently restricting exports to the U.S., that's causing “Western scientists and companies to embark on increasingly novel ways to develop alternative sources,” reports Jon Emont of The Wall Street Journal. One relatively inexpensive idea is to harvest plants grown in mineral-rich soil and purify them into nickel concentrate, which can create stainless steel and other metals.
Americans are waking up to all-time-high coffee prices.

Some may blame President Donald Trump’s 25% tariff threat on Colombian products for the jump in coffee prices; however, coffee costs began climbing long before the Trump-Petro dustup. “Coffee futures have been elevated since 2011 as bad weather has plagued key coffee-growing regions like Brazil and Colombia," reports Vanessa Yurkevich of CNN. "And the region’s next crop isn’t expected to produce a bigger yield. . . . With or without a threatened tariff, coffee prices are high and will likely continue rising.”

How the new administration is addressing illegal immigration to the U.S. is hashed over by news media multiple times a day. However, the discussions toss around a lot of terms many Americans may not fully understand. Two scholars of immigration "who closely follow public discussions about immigration policy, trends and terminology" help de-mystify immigration terms, write Ernesto CastaƱeda and Daniel Jenks for The Conversation. "Understanding the many different immigration terms – some technical, some not – can help people better understand immigration news. While not an exhaustive list, there are 10 important terms to know."

When President Donald Trump ordered the name of North America’s tallest peak to be "changed from Denali back to Mount McKinley in honor of the nation’s 25th president, William McKinley, he put the spotlight on the U.S. Board on Geographic Names. . . . A little-known panel made up of officials from several federal agencies that has been in existence since 1890," reports Susan Montoya Bryan of The Associated Press. Under the Trump administration, the board "will have new members, but the makeup will be the same with representatives from several agencies ranging from the Interior and Commerce departments to the Post Office and the Library of Congress. Even the CIA plays a role when the board considers place names beyond U.S. borders."

The killing of UnitedHealthcare CEO Brian Thompson in New York City in December set off a maelstrom of emotion from Americans sick of dealing with the U.S. health care system. The shooting compelled many U.S. physicians to speak out about what they think are the systemic issues with U.S. health care companies.
