get ahold of the folks at fungi perfecti. Paul stamits might be working on something to abate heavy metal my method is to not worry about it. Sorry folks will be shocked but its this way; it takes lots of lead to really nail you and your just not gonna get that much unless you are eating paint chips. so dont eat the paint chips, use lead pipes, grind the lead ingots into powder in an enclosed space with no dust mask. Etc. I would be will ing to bet that most of your veggies wont have a detectable level of lead. Sorry i know its not a popular stance in todays world but it sure beats being paranoid about every thing. I think that if I where you I would also go look at the actual literature and research so i could make a really informed decision.
Need more info?

We're looking at several different places, but as an example, one outbuilding has all interior and exterior paint coming off in large, very thick chips. The roof looks like it failed some time ago, so rainwater has been running over the interior walls and draining out somewhere.
It did take a look a Fungi Perfecti yesterday and exchanged some emails with them. Looks like there is a ton of research that validates using fungi for lead remediation but no documented/practical system available yet.
I've had my soil out the front lead-tested and it was very contaminated near the houses' dripline.
I was planning to plant edibles out the front and did lots of research after getting the results.
Lead apparently has no effect on plants and is relatively inert. The main danger is ingesting lead from the soil, so I only grow fruiting plants and mulch the area really heavily.
That said, I'd be wanting to get those big paint-flakes to a 'toxic stuff' type dump.
I did lots of research on phytoremediation. From what I can see, it's a very, very slow process, whatever method is used.
My main concen would be animals, kids and pregnant women. If there's going to be any of them around, I'd avoid a clearly lead-contaminated place.
