One should not automtically assume that laws are broken here. 

(Rant begins here)

First of all, it is the States that set the limits of what can and
cannot be dumped. All States must meet Federal standards,but States are
free to determine how they do that. (It's one of the benefits of the
American Revolution) Some states are more heavily regulated than others.
California and Colorado come to mind immediately.

Different organizations, locations and circumstances may allow for
disposal of products that may be diluted to such a degree as to be
negligable in the waste stream. Our institution generates 65,000 gallons
of waste water daily, which allows us to make the dilution limits of
anything that our histo lab could produce in a day. 

No laws are broken if I should pour xylene, formalin, alcohols or other
common compounds that we might generate on even our busiest days into
the waste stream. 

HOWEVER, while we may be allowed to do so by state and local
regulations, we have decided it is not prudent to do so and so we
collect, ship, neutralize or recycle most all that the histo lab
generates. We do this at the lab level, with lab funding. It is the
responsible thing to do, and we are morally and ethically bound to do
so, but we are not outside the law if we do not.

If your local municipal waste systems people give you the green light on
dumping formalin down the drain..... you are not breaking the law,
federal or otherwise, in doing so. 

It is true that if you wish to affect things globally, one has to be
responsible locally.

Here is what my rant comes down to.... Make certain that you are meeting
local standards for your chemical disposal or you may well be breaking
the law. And a big thank you (from myself, my children, grandchildren
and great-grand children and that lady who sells me the slurpee at the
local convenience store) for anything anyone is doing above and beyond
that. 

:)Rant is over... Have a nice day :)

I was a little distressed to read the message from Amy in Camp Hill,
Pennsylvania declaring she dumps everything ("and I mean everything")
from her histology lab down the drain. There are a bunch of Federal Laws
governing handling and disposal of chemicals used in the histology
laboratory and she appears to be breaking several. The wastewater law
limits how much formalin you can discard down the sink (and you cannot
dilute as you go). The same law forbids disposal of organic solvents
like xylene, or solutions containing organic solvents. Local laws in
Pennsylvania may be more strict.

I recommend to Amy that she purchases a book like, "Hazardous materials
in the histopathology laboratory" by Janet & Richard Dapson and read the
whole thing cover to cover!
