Scavengers Unearth Buried History — and Maybe Radiation — at Dead Horse Bay“It’s the closest you can come to time travel.” Cured, New York, By Caroline Spivack  Aug 25, 2020, “It’s pretty devastating,” said Vanessa Dudley of the radiation recently discovered at Dead Horse Bay, a cove in southeastern Brooklyn that was once, many years ago, home to a landfill. For decades, the bay and its surrounding area have been burping up intriguing early-20th-century detritus onto the beach. Dudley, an administrator at Weill Cornell Medicine, is one of many treasure hunters and artists who regularly visited the beach to pick through mud-flecked glass bottles, ceramic shards, and rusted bits of metal. “You can see the lives of people through these objects. It’s like their memory lives on through them.”

But earlier this month, the three footpaths that snake from Flatbush Avenue through thick brush to the beach were marked with canary-yellow signs warning: “Danger Area Closed. Potential Hazardous Material.” Authorities had closed the southern half of the bay (near Floyd Bennett Field) following the discovery of radioactive material on the beach and near one of the paths. The radiation was first noticed during an environmental survey in 2019, when the National Park Service (which manages the bay as part of the Gateway National Recreation Area) discovered 31 locations along the shore and nearby trails with excessive levels of gamma radiation. At two of those sites, the culprits turned out to be old deck markers — small, glowing disks that were once used on Navy ships — that were leaking radium-226. These were recently removed, and the possibility of a more extensive cleanup is now being considered……..

In 1926, after many of the factories had moved elsewhere, Barren Island was connected via landfill to the mainland. In the 1950s, Robert Moses further expanded the area’s land mass by building landfills. Moses flooded the area with the city’s garbage — much of which was likely the rubble of other neighborhoods Moses himself destroyed as he reshaped New York — and then covered it with a layer of topsoil. Erosion has since released much of that debris, which collects at the bay’s eastern shore, providing New Yorkers with an eclectic compendium of 20th-century trash. But in light of new knowledge about the radiation there, exploring that garbage — and discovering the clues it holds about the city’s history — comes at a risk. ……… https://ny.curbed.com/2020/8/25/21398976/dead-horse-bay-beach-brooklyn-radiation-scavengers
