Hydrogen Sulfide levels effected by amount of water used and the ground water table

CUSTOMER WRITES:

I have increased the chlorine and it seems to be doing the trick.  Thanks for all your help.  One last question, what did you mean by; Are you using extra water for irrigation lately?  The irrigation water is drawn prior to the treatment system.  How could that be a contributing factor?  

 

** The more water used from the Well, the higher the concentration of hydrogen sulfide you will be "pulling up" from the ground.

Some people have "no" odor, except when they use 50 - 100 gallons or more. And any Well that has hydrogen sulfide already, will have a higher concentration coming from the Well as the water demand increases ( i.e. watering the lawn, filling the swimming pool ) and as the actual water table in the ground drops ( during "dry spells" ).

Once the summer rains begin, and the water table rises back to normal levels, and less water is used, then the level of hydrogen sulfide in the water drops back to "normal" levels.
