Another source is supposed to be sulphate (gypsum, anhydrite) in the
rocks. that's not uncommon in eastern Ontario. You're near Ottawa, eh?

I'd think that using turbulent water into buckets will probably
disperse most of the sulphur gas.

Thanks Steve, that's interesting about the iron. I dug out an old water
test and they didn't test for H2S unfortunately, but there was a small
(+2) amount of sheated bacteria or iron bacteria, leptothrix spp. This
is why I shock the well periodically, as it leaves a red residue inside
the toilet tank. I'm attributing the odour to H2S since it is
intermittent.

I don't think the iron bacteria are anything which would threaten the
fish. Is the (gypsum, anhydrite) sulphate characteristics similar to H2S
(in regards to threat to fish and the ability to be released through
aeration)?

We don't have the sulphur smell but do get the orange residue. I use
this water straight out of the tap, unconditioned - no problems. These
is lots of iron in the water here. Crypts love it :-)
