Typically the cause is water staying in the water heater too long. This causes the water to turn stagnant. Single handle type water faucets are typically being used in these situations and are not being fully turned to the cold position. This can occur when a water heater is too large for the amount of hot water typically used. It can also occur when the dip tube (cold water inlet) in the water heater deteriorates. Flushing out the water heater will provide an immediate temporary solution.

You would know it if you had this problem! In some parts of the country, drinking water can contain the chemical hydrogen sulfide, which smells just like rotten eggs. This can occur when water comes into contact with organic matter or with some minerals, such as pyrite. The situation mostly occurs as ground water filters through organic material or rocks.

When water is enriched with nutrients, eventually anaerobic bacteria, which do not need oxygen to practice their functions, will become highly active. These bacteria produce certain gasses during their activities. One of these gases is hydrogen sulphide. This compounds smells like rotten eggs. When water smells like rotten eggs we can conclude that there is hydrogen present, due to a shortage of oxygen in the specific water.

It sounds as if you have a problem with Hydrogen Sulfide in your water. Water absorbs this gas as it passes through the ground. When you turn on your faucet, you actually vent the gas from your tap water. Hydrogen sulfide can be treated with oxidation and carbon filtration. The water then passes through a filter that removes the sulfur. The result is water free of the "rotten egg" smell you describe.

A foul odor is most likely due to biologic growth in the chemistry tanks. When the water and chemistry is emptied, clean the tanks well with a 1% solution of household bleach and water. Rinse thoroughly then refill the tanks.

The rotten egg smell is caused by hydrogen sulfide (H 2S) gas. Although the smell is unpleasant it is not harmful. Water heater tanks can provide an ideal environment for the production of hydrogen sulfide gas because it is a result of the corrosion of metals, such as the steel in a water heater. Although most water heaters are glass lined to prevent corrosion, it is impossible to prevent cracks from occurring.

During the ferment, many beer yeast's, particularly lager strains, give off sulfur compounds. This is not a problem and your beer is not spoiled. As the ferment proceeds, the amount of sulfur smell will decrease, and sulfur smell will not be present in the finished beer.

A frequent cause of musty, earthy odors, especially toward the end of the summer, is naturally occurring organic compounds derived from the decay of plant material in lakes and reservoirs. The odors can be objectionable, but generally are not harmful to health. However, odors can be caused by other constituents as well, so you may want to call your local Health Department and mention the odor to them.

The smell of rotten eggs is common when the battery is filled for the first time. When you fill the battery with acid, the initial reaction between the plates and the acid produces sulfur dioxide. It smells like rotten eggs, but it is harmless and will dissipate within a short time.

Rotten egg odor is cause by the presence of hydrogen sulfide (sulfur) in the water. The hydrogen sulfide can be treated with a chlorinator system or a Manganese Greensand Filter.

Strong, “rotten-egg” odors in water are usually the result of the decomposition of underground organic deposits. As water is drawn to the surface, hydrogen sulfide gas can be released to the atmosphere. In strong concentrations, this gas is flammable and poisonous. It rapidly tarnishes silver, and is toxic to aquarium fish in sufficient quantities. As little as 5 parts per million (0.5 ppm) hydrogen sulfide can be tasted in your drinking water.

You may have hydrogen sulfide in the water and your system may not be designed to address this issue. You may have a bacteria growth in the system or filter cartridge. If you have a filter cartridge, change it and clean the sump with bleach, rinse, add a quarter teaspoon of bleach and put the new filter in.

Mesosilver will turn clear as water if it is frozen solid or contaminated in use. To prevent contamination:

Your water utility regulates the amount of chlorine added to disinfect your drinking water. Sometimes, after hard rainstorms or during high spring runoff, more chlorine may be added to ensure that your water is safe to drink. If you dislike the taste or smell of chlorine, you should consider installing a water filter. OMNI's Whole House filter Model U25 will reduce chlorine in the water entering your home. Any of the OMNI Undersink filters will reduce chlorine in your water at the tap.

Chlorine is added to the water for disinfection. It killls disease-causing microorganisms called pathogens. The Safe Drinking Water Act requires that a chlorine residual be maintained throughout the entire distribution system. To accomplish this, sufficient amounts of chlorine must be added at the treatment plants and at booster chlorination sites located in certain areas of the distribution system.
