As the lead erodes and disintegrates it contaminates the water and the soil. Unsafe levels of it are found in 44 of 130 underwater sample sites tested by independent labs for the WSJ.

It was found in the Willamette River in Oregon, in the Mississippi river banks in Louisiana, in the Detroit River in Michigan and the Passaic river in New Jersey.
