Hi, not really no smile
as far as I can tell,
the standard/tests are mostly about preserving flavor/taste,
and making sure the seals don't fail, the can doesn't rust , mechanical stuff


You can also see this part of same page/document
Quote:

.....
C. The water must meet the applicable government standards for drinking water in effect at the place where it is packed. In addition the water must not contain more than -
1. 500 mg/l of salt (NaCl).
......
1. Chemical and biological analysis. Evidence must be provided that the water meets the government requirements for drinking water in effect at the place the water is packed. Two containers of water must be analyzed for -

a. sterility,
b. salt content, and
c. presence of organic matter, sediment, and odor.


None of those are tests for leaching of chemicals.
The advertising for all these different emergency drinking water
says "U.S. Coast Guard Approved" but they don't mention leaching.

I imagine if there is zero leaching, that fact would be advertised.
The salt could be used to maintain the taste.
