Eggs? HYDROGEN SULFIDE AND SULFUR BACTERIA IN WELL Hydrogen
sulfide gas (H2S) can occur in wells anywhere in Minnesota, and
gives the water a characteristic "rotten egg" taste or odor.
This brochure provides basic information about hydrogen sulfide
gas and sulfur bacteria and discusses actions that you can take
to minimize their effects. What are the sources of hydrogen
sulfide in well water and the water distribution system?
Hydrogen sulfide gas can result from a number of different
sources. It can occur naturally in groundwater. It can be
produced by certain "sulfur bacteria" in the groundwater, in the
well, or in the water distribution system. It can be produced
also by sulfur bacteria or chemical reactions inside water
heaters. In rare instances, it can result from pollution. The
source of the gas is important when considering treatment
options. Are sulfur bacteria or hydrogen sulfide In most cases,
the rotten egg smell does not relate to the san
