Most of it is environmental madness. A small portion is common sense. Unfortunately that particular portion does not even enter into it. It's the gobbledegook they're filling up schoolchildren's heads with. Turns them into militants. Do what you think is right. If you think you are actually generating some big-time poison, then dispense with it appropriately. A gallon of fixer down the drain every year is less in the scheme of things is less than peeing in your swim trunks in the ocean.
there can be upto 1/4 oz of silver in a gallon of spent fixer.
its mainly the silver in the fixer that isn't good to go down the drain.
if you have metal pipes it may corrode them if done for a long enough time ...
and the silver likes to kill off beneficial bacteria in home septic and municipal sewer systems.
25+ years ago kodak used to say to just drain it because it posed no problems but they now
say not to dump it down the drain and to remove the silver from it ...
don't worry about a hornet's nest HFT III likes to assume different user names
and go on and on about politics ...
in a previous thread he said spent fixer was harmless, but later he added
he used it as a herbicide on his property.
i hope he gets his well water tested
if you have any magnet questions &c feel free to PM me
i sell them as well as other stuff to recover the silver in your fixer.
Home darkrooms have been around for many, many years, all over the world. Considering that, one might find plenty of cases of harm to sewage disposal and septic systems and the environment from home darkrooms, if it actually does happen. Does anyone know of any actual cases where harm to a sewer system or septic system has been attributed to photographic solutions being poured down a drain from a small, home darkroom? Or harm to the environment or groundwater?

within a few years they were scewed...
and i also know someone else who was fined about $100,000.00 for not complying with local regulations.
the local laws are different no matter where you go. it is best to find out where you live what is right for your situation.
( me? i live in a place where the rules are very strict and i obey them. )
the funnything is there are always people who claim all sorts of nonsense, especially on online fora.
a bunch of years ago there was someone here on apug, who claimed she was a chemist &c, and then claimed
that selenium toner was harmless ( even though the packaging suggests different ) because there
are trace amounts of selenium in multi vitamins.
just watch dr house to realize there is selenium in brazil nuts too, but if you eat too many brazil nuts
you will get sick with something that looks like cancer or radiation poisoning ... and the best cure for it
is a tea made of the larvae from some sort of bug ....
that might work for selenium poising ...
i don't think there is a larva you can flush down your drain to counteract the affects silver ( other than not dumping it ).
jnanian is an advertiser here, and a supporter. I have nothing to say against him. The topic is disposing of used fixer. Do what you think is right. I have no further comment.As I have seen, an advertiser can cancel your account.
jnanian, I will take your word for it but I would prefer to see some sort of case histories that are documented. I have never seen any in any of the photographic literature. Personally I have been pouring my chemistry down the drain for years and my county requires septic systems to be inspected every three years and I have had no problems (you'll have take my word on that). Of course, YMMV.
i wish i could give you the names but for privacy reasons i won't.
you are lucky your system can handle your situation ...
You mean, not everyone does that? Seriously, though, I just dump mine in my neighbors garden :wizard:
