fixer with over 5 ppm of silver is considered hazardous waste by the
EPA; some state laws are stricter; it's easy to assume that casual use
can't possibly be significant, but fixer is not the only potential
source of silver in wastewater; for example hobby jewelers may emit it
too
I recall a few decades ago when the EPA was turning it's eye to the
photofinishing industry, there were a number of California
municipalities whose tap water had enough naturally occuring silver
dissolved in it to make it illegal according to the EPA.
Such is the intelligence of government enforcement.
I agree that worrying about the amount of silver getting into the
environment from used fixer is silly. But I think the statement above is
probably more of a comment on the quality of municipal tap water than
the silliness of the EPA.
