The only fixture I've noticed red tint is in the toilet bowl if I let it go
without cleaning long enough. A ring a the surface level in the toilet
about a 1/2" wide. None on the sediment filter bowl, or, the carbon filter
in place for 3 months at a time.

Yet, the obvious level of hydrogen sulfide gas at the well is very high due
to its odor level. The level of gas not only varies with lack of water
usage, but also, with locally heavy rains.

That chemical reaction is no where in my message.

H2S is a byproduct of anaerobic digestion of organic material, and goes
into water as
hydrogen sulfide. "hydrogen sulfide is weakly acidic, dissociating in
aqueous
solution into hydrogen cations H+ and the hydrosulfide anion HS-: H2S ?
HS- + H+ Ka
= 1.3×10-7 mol/L; pKa = 6.89"

"In the management of water-supply wells, iron bacteria are bacteria that
derive the
energy they need to live and multiply by oxidizing dissolved ferrous iron
(or the
less frequently available manganese and aluminium). .....The proliferation
of iron
bacteria, in some way, increases the chance of sulfur bacteria
infestation.

Common effects of excess iron in water are a reddish-brown color, stained
laundry and
poor tasting coffee. An equally common but less well understood problem is
infestation of water supplies with iron bacteria. Iron bacteria are a
natural part of
the environment in most parts of the world. These microorganisms combine
dissolved
iron or manganese with oxygen and use it to form rust-colored deposits. In
the
process, the bacteria produce a brown slime that builds up on well
screens, pipes,
and plumbing fixtures.

Tastes and Odors - Iron bacteria often produce unpleasant tastes and odors
commonly
reported as: "swampy," "oily or petroleum," "cucumber," "sewage," "rotten
vegetation," or "musty." The taste or odor may be more noticeable after
the water has
not been used for some time. Iron bacteria do not produce hydrogen
sulfide, the
"rotten egg" smell, but do create an environment where sulfur bacteria can
grow and
produce hydrogen sulfide."

"The purple sulfur bacteria are a group of Proteobacteria capable of
photosynthesis,
collectively referred to as purple bacteria. They are anaerobic or
microaerophilic,
and are often found in hot springs or stagnant water. Unlike plants ,
algae, and
cyanobacteria, they do not use water as their reducing agent, and so do
not produce
oxygen. Instead they use hydrogen sulfide, which is oxidized to produce
granules of
elemental sulfur. This in turn may be oxidized to form sulfuric acid."
These
bacteria are often sold to people to reduce the sludge in ponds and sewage
systems.

CO2 goes into water to make H2CO3, carbonic acid.

Under pressure both are in solution like in a well. When pumped out of
the well and
pressure is released, the gases come out of solution.

The simple test for both is pump out a 5 gallon bucket of water, take a pH
test.
aerate and after 24 hours test pH again. If the pH rises then the gases
have come
out of solution. If it is H2S, that can be smelled in very small amounts.

See, just cant spontaneously combine chemical reactions. Ingrid

H2S + 2CO2 - H2SO4 + C2 doesn't make any sense. Makes all other
