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 odor of hydrogen sulfide gas can be detected in water at a very low level. Smell the water coming out of the hot and cold water faucets. Determine which faucets have the odor. The rotten egg smell will often be more noticeable from the hot water because more of the gas is vaporized.
Hydrogen sulfide gas produces an offensive rotten egg or sulfur water odor and taste in the water. In some cases, the odor may be noticeable only when the water is initially turned on or when hot water is run. Heat forces the gas into the air which may cause the odor to be especially offensive in a shower. Occasionally, a hot water heater is a source of hydrogen sulfide odor. The magnesium corrosion control rod present in many hot water heaters can chemically reduce naturally occurring sulfates to hydrogen sulfide.
