AT&T, Verizon and other telecommunications companies have left behind a sprawling network of cables covered in toxic lead that stretches across the US, under the water, in the soil, and on poles overhead. As the lead degrades, it is ending up in places where Americans live, work and play. The lead can be found on the banks of the Mississippi River in Louisiana, the Detroit River in Michigan, the Willamette River in Oregon, and the Passaic River in New Jersey, according to tests of samples from nearly 130 underwater-cable sites, conducted by several independent laboratories.
