What I’m saying is the contamination in Cambridge is mostly not from
those sources, but from 19th century and earlier smelting operations. I
have seen a lead contamination map of the boston/cambridge/somerville
area, and it’s pretty bad.
Growing anything for human consumption in that area without having both
the soil and the produce tested for lead is irresponsible. Possibly
illegal if you sell it.
Maybe if you had the topsoil removed, trucked in new soil, that might be
safe. But I would still get it tested.
