Julie,

Definitely look at SW-846, "Test Methods for Evaluating Solid Waste,
Physical/Chemical Methods", found here:
http://www.epa.gov/waste/hazard/testmethods/index.htm

I would also look to the POTW that you discharge to and coordinate your
methods with them.  Unless you ship your wastewater off site, you are
definitely regulated and probably have to comply with a discharge permit
and some various federal categorical pre- and post- treatment standards.

Subject: [DCHAS-L] Wastewater testing

We are looking into testing for metal concentrations in our waste water
in house.  We are a metal fabrication facility in Indiana, and need to
test for Cadmium, Chromium, Copper, Lead, Nickel, Silver, and Zinc.

I have been tasked with investigating methods and equipment that will be
required.  Can anyone in this group share their experience/knowledge in
testing for metal concentrations in wastewater?  What methods do you
use?  What works best?  Are there additional resources that you can
point me towards?

Thanks,
