Why does my water smell like Rotton Eggs?
A.HYDROGEN SULFIDE AND SULFUR BACTERIA IN WELL WATER Reprinted from an article by the Minnesota Rural Water Association. 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 harmful? In most cases, the
