I do not know the source of the H2S - I am thinking that there is a tonne of sulphate reducing bacteria in the aquifer. They enjoy the anaerobic conditions and thrive, producing H2S in the meantime. However, the TOC is probably an indication of an old organic bed of some kind. I do not know the...
1) We were not concerned about CO2. That was a recommendation by another party. I doubt there is much CO2 and it was recommended to introduce it to lower the pH
2) The aeration was for oxidation. My orignal idea was simply to use fine microbubbles to aerate and then filter out the sulfur...
RAW WATER
Fluoride 4.43 mg/L
pH 9.05
Sulfide as S 8.5 mg/L (in lab with field fixing agent)
(We have a Hach field testing kit on order)
Turbidity 1.3 NTU
TREATED WATER (so the Raw water, with Chlorine added only)
Calcium 1.7 mg/L
Iron < 0.03 mg/L
Magnesium 0.1 mg/L
Manganese...
The latter did cross my mind!
I will post the water analysis shortly
I realize I am trying to look for a simple solution for something that is probably quite complex. Thanks

We have been asked to assist the community we live in (24 homes) with a source water problem. The water has a pH of 9.1 - 9.2 and sulfide value of around 8.0 ppm. At present the current operator is dosing about 43 ppm of chlorine, the water is gassing off noticable...
