“We don’t know what to look for” What utter dogshit. I work in environmental testing and it’s really not hard to blanket test soil samples for pretty much anything we currently recognize as “bad.”

They don’t want to spend the money on testing only to lose more money when they can’t sell their product.

I feel like you could ask your local high schools chemistry teacher what metals you should test for after a lithium fire

It's not as accurate as mass spec but generally speaking you can test for geavy metals using certain acid and color changing indicators (in known concentrations) over a range of sample dilutions. Even better if you have a reference sample of a known concentration of the target, like manganese. Sometimes the chemical is not itself an acid but nevertheless reacts with the target.

For example, high concentrations of manganese will react with peeiodate to make a red/broan color. You can buy a set of 100 pouches of periodate for manganese testing on Amazon for $50.
