UK suburban soil can also be bad as people used to throw fireplace ashes in their gardens, which can concentrate contaminants. I ate from my home allotment for years until a neighbour told me he had recently tested his soil and found it heavy with lead and other rubbish.


did he find a way to de-pollute ?


Soaking the soil with EDTA solution might do it.

(EDTA is also used medically for heavy metal poisoning).


No he just grew flowers from then on and I moved to pots and grow bags


You can bioremediate lead using sunflowers.
