Even worse is H2S Hydrogen Sulfide.

In order -- yes, it's worse.

It is as small as water, can't mechanically filter it.
It can out gas from water and attack the lungs and blood system.
Quick painful death. e.g. poison gas well.

The only filtration method is over silver metal. Or massive
oxygenation. Banks of water towers that spray fine mist.

Silver is hardly the only way, or even the preferred way to remove it.
Using a silver-bearing filter requires very expensive recycling of the
silver sulfide created, and it's a pain as well as expensive.

H2S can be removed by chlorination (which some folks don't like),
converting the sulfur to insoluble sulfides that CAN be filtered
mechanically. It can also be removed by so-called "manganese green
sand" filters. Or, as you suggested above, by aeration.

That method doesn't USE oxygenation, although that occurs as a byproduct
of the spraying. H2S has a high vapor pressure. Break the water up into
small enough droplets or thin enough sheets, and H2S will gas-off by
itself. Residence time in the tank with the top surface exposed to
circulating air after the first aeration improves the degree of
'desulfurization'. The downside of the method is that it requires two
pumps: One for lift-and-spraying, the other to move water from the
desulfuring tank to the pressure tank.

No "banks of water towers" are required. We have strong "sulfur water"
here. For residential service, a single 500-gallon 'square' (high as
wide) tank (heavily ventilated and screened) with four 'sheeting
nozzles' spraying the fresh well water over the top, and plenty of air
circulation serves fine to remove all of it.

The Hydrogen is so small it invades iron and steel and plastic
pipe. In Fe materials - rust and exfoliation occurs. Death of
a water system by a thousand cuts. The sulfur ionizes to SO2
rotten egg gas.

Nope... "rotten egg gas" is H2S. SO2 is "sour" (acid in smell and taste)
If SO2 is released or created, it combines with water to form sulfurOUS
acid, that is pretty corrosive. It's not a natural product of sulfur
water aeration, and seldom is present in well water.

I will agree that 'sulfur water' rots pipes out faster than 'good' water,
but only if it GETS INTO your COPPER or brass pipes. We remove the H2S
before it gets into anything but the iron lift pipe and first pump (iron,
also). HS2 doesn't tend to affect iron much after that very thin 'black
layer' you mention forms.

Mine's only about 17 years old right now...still going strong, though; no
leaks, no corrosion. And when I had the lift pump off for replacement
(due to lightning) about a year ago, NO visible diminishment of the wall
thickness of the pipe.
