Subject: Re: Used fixer?
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.
