Across the country, telecom companies have left behind more than 2,000 cables containing lead, a WSJ investigation has found, part of a decaying network installed under the old Bell System. ⁠
⁠
Reporters found cables protruding from banks, resting under bridges, snaking under water and drooping from the air at dozens of sites. Testing showed that many are leaching toxic metal into the ground and water.⁠
⁠
Southern Louisiana’s 125-mile-long Bayou Teche flows through a region particularly dense with cables. Southern Bell filed permits with the U.S. Army Corps of Engineers starting in the 1930s to place more than a dozen cables across the bayou.⁠
⁠
Journal reporters, with the assistance of environmental researchers, tested the water in nine places along the bayou and the sediment in three of them. Of those 12 tests, eight showed elevated levels of lead. A sediment sample near the cable in New Iberia exceeded the safety recommendation set by the Environmental Protection Agency for areas where children play.⁠
⁠
Southern Bell is now part of AT&T, which didn’t respond to requests for comment on the cables in New Iberia and surrounding areas. AT&T said in a written statement it doesn’t believe lead-sheathed cables pose a public-health issue. “The health, safety and well-being of our people, our customers, and our communities is of paramount importance,” it said. “For decades, we have managed legacy lead-clad cables in compliance with applicable laws and regulations.”⁠
