"German researchers found extremely dangerous levels of up to 17% arsenic in the soil"
That seems too high to be true. The page doesn't give the source, but I wonder if something like bioavailability got misinterpreted as composition.

I found this study (https://hal-insu.archives-ouvertes.fr/insu-01267232/document) but I am afraid I don't know how to read the results.
I assume that 17% is the absolute maximum proportion of arsenic ever found in a single small sample.
These commas appear to be thousands separators, so that's a maximum of 73 grams per kilogram or 7% per mass of a soil sample. I'm not a doctor, but I would advise against eating significant amounts of these soil samples.
