Don't worry about the silver. The chemical environment of a septic tank is a
VERY strong reducing one. There is lots of sulfide ion present and any silver
ion is rapidly converted to silver sulfide.which is very insoluble in water.
In fact the Ksp is 6 x 10-51 making it one of the most insoluble metal
sulfides. Silver will not get into the environment.

Just found out that TN has very little hazardous waste disposal set up. We have
one day in our county when you can bring hazardous waste to the fairgrounds.
The other counties also each have one day in spring and fall. So I guess I'll
have to store the stuff until a county near me has a day.

I just moved my darkroom to rural TN this summer and now it's ready to go. But
I'm trying to figure out how to dispose of used developer and fixer. I have a
septic system, and the little bit of research I've done today indicates that I
shouldn't just put it into the septic system (according to Kodak). I just
called the Solid Waste people here in Putnam County, and they are going to look
into it for me, but they didn't really know what I was talking about and I have
the feeling they are going to say, "We can't deal with this." So what would be
another option?
