Hydrogen Sulfide in Water

Hydrogen Sulfide in Water

        About six months ago, my friends asked me to help determine what water treatment system to chose for a private house. The source of water supply is a 40 meters deep-well. Initially, I assumed that the water will have a composition inherent to groundwater. So, the well is considered to be artesian if it has protection against pollution by surface waters, i.e. it has no contact with the atmosphere and is not polluted with different organics. As a rule, the protection of artesian water provides a layer of clay. A layer of dense clay begins at a depth of an average of 25 to 75 meters. Water can be considered artesian if it located deeper than this layer of clay. In such water there is practically no organic matter and oxygen. If the mineral composition is right (salt content of water should be less than 1000 mg / l), this water is considered drinking.

        On the territory of the Saratov region artesian water begins at a depth of 100 m, so I assumed that the well with a depth of 40 meters is likely to be groundwater. That is, it will be contaminated with organic matter and oxygen will be in the water, because it has contact with surface waters which are rich in organic matter and oxygen.

        I strongly recommended to make a full water analysis for the compliance with the requirements of SanPiN 2.1.4.1074-01 “Drinking water”, but … as you know it is easier said than done.

      So, the water from the well was brought for analysis. I test water for the adjustment of water-chemical mode of boiler rooms. Therefore, I can make an analysis with sufficient accuracy on the following parameters salinity, hardness, alkalinity, pH, iron, oxygen, CO2, ORP.
