To use leaded glass as a landfill daily cover makes a bit of convoluted sense, as when the landfill is full it is capped with a water-resistant cover. Additionally, since the lead is within the glass, it will take quite some time to leach any significant quantities out, even if it is submerged in water.

So the lead will not likely to leach out very quickly in a dry landfill. "likely" is the operative word here. There are probably other lead sources in a landfill so maybe the lead in glass would only make up a small part of the total lead contained within the landfill.

I wonder if the glass guys who DO process leaded glass have a method of actually removing the lead or do they just re-melt the contaminated glass and it and use it to....make Toyotas or whatever?
