Lead Paint Contamination
There have been concerns about the recycling of painted concrete due to possible lead content. The Army Corps of Engineers' Construction Engineering Research Laboratory (CERL) and others have conducted studies to see if lead-based paint in crushed concrete actually poses a hazard. Results concluded that concrete with lead-based paint would be able to be used as clean fill without impervious cover but with some type of soil cover.

Famous quotes containing the words lead and/or paint:
“I wander on, and wave my hands,
And sing, and shake my heavy locks.
The grey wolf knows me; by one ear
I lead along the woodland deer;
The hares run by me growing bold.”
—William Butler Yeats (1865–1939)
“One can write out of love or hate. Hate tells one a great deal about a person. Love makes one become the person. Love, contrary to legend, is not half as blind, at least for writing purposes, as hate. Love can see the evil and not cease to be love. Hate cannot see the good and remain hate. The writer, writing out of hatred, will, thus, paint a far more partial picture than if he had written out of love.”
—Jessamyn West (1902–1984)
