I have come across an article once that Arm and Hammer baking soda is
from Trona Mine. This baking soda is processed from soda ash from
Trona ore (used for making glass also, fiberglass, etc.). I don'at
know which Trona mine A&H sources their soda ash.
Not all Trona mines are good though. Some could have petroleum
industry pollutions through leaks.

Trona is the raw ore from which soda ash is produced. Church and Dwight
refines soda ash into baking soda. They buy their soda ash from mines in
Green River, WY. I believe they buy from all the mines at one time or
another, depending on price.
Bob's Red mill probably buys their baking soda from Church and Dwight,
but I don't know for sure, they could be buying it from China......but
since the mines here produce 90% of the soda ash used in the U.S. it
isn't very likely.

"About 95 percent of Chinese soda ash production is done through an
energy-intensive synthetic process. China produced more than 13 million
short tons in 2008."
I live in Green River, WY, and my husband retired 3 years ago after 33
years working in an underground trona mine.
He has never heard of a petroleum industry pollution "leak", ever. The
"trona patch" is all one contiguous (if I use that word correctly) thing
really, the various companies lease mining rights to an area, but
basically all the mines are working one huge deposit. It isn't like
following veins of coal or something.
