Does the revenge smoke bombs for rodents damage well water?

Question:I have well water on my property and have gophers.
I want to use the revenge smoke bomb but I am hesitant because I have well water.

Has anyone used these that have well water, and has it put any toxins into the drinking water.

Thanks

Not a good idea, inhumane in my view. Here is the MSDS for the product, seems like it will not contaminate groundwater.
