Flint’s Water Crisis, 10 Years Later | Underwater Cables Could Help Detect Tsunamis

While progress has been made in replacing water pipes in Flint, many residents say they still don’t know if their tap water is clean or not. Also, scientists are adding sensors to an underwater cable network to monitor changes in the ocean and quickly detect earthquakes and tsunamis.10 Years Later, Flint’s Water Crisis Still Isn’t OverIn 2014, city officials in Flint, Michigan, switched their water source to the Flint River, a move that was projected to save the city $5 million. Instead, the water corroded the city’s lead pipes, which led to multiple negative health impacts for local residents, including lead poisoning, and a Legionnaires’ disease outbreak that resulted in a dozen deaths.Now, almost 30,000 homes and businesses have had their water lines replaced, but 1,900 others have still not been reviewed. The city says they’ve reached out to owners of these properties with no response and have not been able to move forward, but activists claim that the city hasn’t contacted them.Guest host Arielle Duhaime-Ross is joined by Vox senior correspondent Umair Irfan to talk about this and other top science news from this week, including new Long COVID trials that are underway, regulations from the EPA that require new coal and gas plants to limit 90% of their CO2 emissions, and a positive software update for Voyager 1.How Underwater Telecom Cables Could Help Detect TsunamisDeep under the sea, a wide network of cables crisscrosses the ocean floor, keeping the internet and other telecommunications online. While these cables have a big job to do, researchers want to make them even more important by giving them the ability to detect seismic activity and alert those on land of a tsunami risk earlier than is currently possible.Portugal is about to be the testing ground for these new, integrated cables, with a 3,700-kilometer cable to be installed between the Iberian country and the Madeira and Azores archipelagoes. This is a fitting place to pilot this, as Lisbon was the site of a devastating 1755 earthquake and tsunami that killed tens of thousands.Joining guest host Arielle Duhaime-Ross to discuss the potential of smart cables is Dr. Bruce Howe, research professor of engineering at the University of Hawaii and chair of the United Nation’s SMART Cables Joint Task Force.Transcripts for each segment will be available after the show airs on sciencefriday.com.   Subscribe to this podcast.
