Click âDisease of the Week,â find rotavirus, and take the quiz to test your knowledge! Rotavirus is a contagious virus that can cause gastroenteritis (inflammation of the stomach and intestines). Symptoms include severe watery diarrhea, often with vomiting, fever, and abdominal pain.
The incidence of rotten egg odor or black water in hot water lines is due to the reaction of. sulfates and micro-organisms in the water that create Hydrogen Sulfide (H2S). This is a water. chemistry condition, rather than a water heater problem.
If you notice this smell in your water, it probably contains hydrogen sulfide (H2S) gas. Sources of this gas include:Decay of organic matter or chemical reactions with sulfur-containing minerals in soil and rock. If the smell is only from the hot water tap, the source is most likely your water heater. 2  If the smell is from both hot and cold taps, but only from water treated by a water softener, you may have sulfur-reducing bacteria in your water softener.
