Our national analysis of samples collected from 16 cities found that out of 15,595 household soil samples, 12.3% – one in every eight – exceeded the old federal screening level of 400 parts per million. When the standard is adjusted down to the proposed level of 200 parts per million, 23.7% of households – nearly 1 in 4 – contain a lead hazard

Thank god I don’t touch grass!

More seriously though, does the lead concentration matter if no food is planted in the soil?
