(extra points to those who can see one of the challenges bio-remediation of
de-icing fluids...hint, when are the fluids used? extra bonus points to
those who can guess what is often done with the recovered de-icing fluids,
no points to those who can guess what used to be done with de-icing fluids -
"gee mum, why is that creek still flowing in January?")

I get your point but, deicing fluid is used on aircraft, in winter when it
is quite cold, while they sit on the ramp, most often at the departure gate
just before getting in line taxiing to takeoff point on the runway. The
deicing fluid is left on the ground/ramp and people drive fuel trucks,
baggage tugs/carts and walk in it. It is NOT recovered. No attempt is made
to do that. When the ramp area drains due to snow melt and rain (the ramp is
not "washed", ever-only sometimes "swept"), it drains into the sewer system,
and in the case here in Salt Lake, drains into the gray water system then
into the Great Salt Lake. When snow falls on the ramp area where the
residue/remnant deicing fluid sits, the snow is plowed, put into trucks and
hauled to a central dumping point at the airport, on soil.....which then
contaminates the ground water system after being filtered by mother nature.
I walked in it for almost 20 years.
