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:
“The greatest, or rather the most prominent, part of this city was constructed with the design to offer the deadest resistance to leaden and iron missiles that might be cast against it. But it is a remarkable meteorological and psychological fact, that it is rarely known to rain lead with much violence, except on places so constructed.”
—Henry David Thoreau (1817–1862)
“Your business is not to catch men with show,
With homage to the perishable clay,
But lift them over it, ignore it all,
Make them forget there’s such a thing as flesh.
Your business is to paint the souls of men—”
—Robert Browning (1812–1889)
