I Haven't flown an airplane for around 20+ years but I remember most of the
preflight procedure from memory. One thing we did was after taking the fuel
sample, we would chuck it out on the ground.
You make reference to EPA's take on that.
I'm certain there are recommendations against- if not outright prohibitions
on tossing fuel on the ground nowadays.
What are current approaches to fuel sample disposal and such.

Fuel at $8.00+ per gallon is too precious to "chuck on the ground".
There is a device known as a Gatt Jar that one holds up to the sump to
drain a fuel sample. The top of the Gatt Jar has a lid with a fine mesh
strainer, which is attached to a large (0.5 l) plastic bottle to hold
the fuel. The fuel is then poured back into the tank through the filler
cap.
Some states have environmental laws against "chucking it on the
ground"due to the lead content and potential contamination.
