Wendy,
You're correct about the TCLP, I would at a minimum expect to find silver
and chromium from the photo lab and almost any metal from the metals lab,
especially those used in plating. Depending on the type of film they were
processing you may also find residual organics form the color dyes. Beyond
that there may be salts of acids such as acetic and, ammonium dichromate,
sulfite(s), hydroxides etc.

Hey all,
I just ran into an interesting situation. Some years ago, there was a
plumbing leak in a pipe tunnel. The "grey" water in the lines that leaked
out originated in a photography teaching lab and a metal arts teaching
lab. After the leak was fixed, the water was simply allowed to dry in the
tunnel and now there is a lot of dust left on the floor. There will be a
lot of work performed in the tunnels in the next month or two, and this
will certainly stir up the dust.
I know what processes are done there now, and I have a good idea of
"recent" history (the past 10 years or so), but I'm not overly familiar
with historical photography lab practices and the photography manager is
newer here than I am. Based on what I do know, I grabbed a sample of the
material and will have it tested to see what might be in there and at what
levels so we can start planning a clean-up of the area. My question to
the list is this: What would you sample for? It would be awesome to have
that mysterious machine from CSI that can analyze molecules in seconds in
the field, all the way down to the brand of perfume and its retailers,
but...... I'm thinking a TCLP for metals is in order, but is there
anything else that I should request of the lab doing the analysis?
Thanks,
Wendy
