Exposure from lead-coated copper, experience with remediation



I have been contacted by someone who has a situation where a condo patio has lead-coated copper
flashing/sheeting on it, and a child in the household has elevated lead levels. The identified
source is direct contact exposure to the lead-coated copper. If anyone has any experience with
removing/remediating this type of situation, I could use your feedback. Here are the pressing
questions:

        1. What is the best, most effective way to prevent the child from direct contact with the
lead sheeting ?

        2. Does anyone know of any actual studies looking at lead content of the rainwater running
off of lead-coated copper? An article at http://www.professionalroofing.net/past/aug00/qa.asp claims
that the lead content of the rainwater is negligible compared to other sources of lead, but it lists
no actual sources that I can look at.

Although they could put a latticework or other physical barrier over most of the lead, there are
areas on the patio that will not be able to be blocked, such as at the threshold under the door
sill.

Could the lead-coated copper be covered with a non-lead flashing? Has anyone done this?

Does anyone know if removing the lead-coated copper will result in lead exposure for the household,
such as when leaded paint is removed? Has anyone removed this stuff or have information on ways to
protect the family during removal?

Any feedback or experience is appreciated.
