Why Does My Water Smell Like Rotten Eggs And How Did It Get There? If you notice this smell in your drinking water, it probably contains hydrogen sulfide (H2S) gas. Hydrogen sulfide gas produces a strong and unpleasant Бrotten eggБ or БsulfurБ odor and taste. In some cases, the odor may be present only when the water is first 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. Sources of this gas include: Decay of organic matter or chemical reactions with sulfur-containing minerals in soil and rock. Sulfate-reducing bacteria which convert naturally occurring sulfate and other sulfur compounds to hydrogen sulfide gas. Providing a warm environment for sulfate-reducing bacteria to live. The magnesium anode supplies electrons that sustain the reaction of sulfate to hydrogen sulfide gas. Is Sulfur Harmful? Sulfur, sulfates and hydrogen sulfates are not generally considered harmful because the taste and odor is so unpleasant at such low levels that the taste and smell would prohibit most people from drinking it well before it reached harmful levels. It is mainly considered a nuisance primarily because of the smell and taste however it can also be corrosive to metals such as iron, steel, copper and brass. It tarnishes silver and can discolors copper and brass utensils. Hydrogen sulfide can cause yellow or black stains on kitchen and bathroom fixtures. Coffee or tea may be discolored and the appearance and taste of cooked foods can be tainted at times. Ways To Get Sulfur And The Smell Of Rotten Eggs Out Of Drinking Water: Chlorination or Chlorine Injection Chlorine will quickly react with hydrogen sulfide to form a tasteless, odorless, yellow particle.


A small amount of chlorine, even household laundry bleach, can be added to any water system to remove hydrogen sulfide. The yellow sulfur particles that remain form a yellow film on clothing and fixtures. A sand or aggregate filter can remove the yellow particles. Aeration Oxygen in the air will react with hydrogen sulfide to form an odorless, dissolved form of sulfur called sulfate. Some yellow sulfur particles may also form after the water is aerated. In an aeration system, compressed air can be injected into the water system but must then be removed from the water. Carbon Filters Very small amounts of hydrogen sulfide can be removed from water with activated carbon filters. The hydrogen sulfide is adsorbed onto the surface of the carbon particles. Periodically, the activated carbon filter must be replaced depending on the amount of hydrogen sulfide in the water. Moderate to high levels of hydrogen sulfide in water will require very frequent filter replacement. in your drinking water,
to discuss your options. Do you notice a particularly nasty smell when you start to run your tap water? Could the water be described as smelling like rotten eggs or sulfur? If this has happened to you, donвt worry, weвre here to help. Surprisingly, this is a very common problem in many households and isnвt as devastating as you might think. Contrary to what you might be thinking now, this may not cost a lot of money in plumbing repairs as you might actually be able to fix the problem yourself.


Letвs take a deeper look as to why your water smells like rotten eggs. The reason your water probably smells like rotten eggs is because it contains some traces of. Even extremely small amounts of hydrogen sulfide can cause your water to have quite the odorous smell! In most cases this smell occurs due to a build-up of hydrogen sulfide in your hot water heater. If you havenвt used your hot water heater in quite some time, this could be the cause of your odor. Is it Harmful? Despite the wretched tingling in your nose you might experience, hydrogen sulfide is actually a non-health risk. If anything all it does is provide an extreme nuisance when found in your water supply. That being said, letвs figure out a way to get rid of your disgusting smell. Before we start to solve anything, first we need to figure out what exactly is causing the rotten egg smell. To do this try running both the hot and cold water in all the faucets in your house. If the smell is coming from just your hot water, then the problem most likely exists from the hot water heater in your house Take note to see if the smell is coming from all of your faucets or just some in particular areas or rooms of your house. If the smell is coming from isolated areas then the problem most likely exists in these drains or pipes and not your entire water supply. Turn on all the faucets in your house and allow them to run for about 10 minutes After this amount of time, turn them off. This should clear out your pipes and hopefully the smell will cease If you figure out the smell only comes from your hot water, then it might be wise to flush your hot water heater.


Without turning off your water supply, find a hose to connect to your drain valve of your hot water heater. Place the other end of the hose outside in a good place where excess water can run After 10 minutes of draining, take a sample of the water. Fill up a cup and determine whether or not there are particles or little pieces of sediment in the cup. You can also try disinfecting your water heater which is a very simple process. Simply turn the temperature of your water heater to 160 degrees and leave it run for a couple of hours. This should kill all bacteria in your water heater Another fix to your rotten-egg smelling water could be as simple as installing in your house. However, this may only be a temporary fix and you will have to replace your water filters every so often. В Itвs also important to note that filters could also be the cause of any rotten egg smell. Replace any if you notice particular sinks are carrying the odor. If you locate the cause of your rotten egg smell to be in your groundwater or distribution system, this problem is going to be a little bit more challenging to solve. I would recommend calling your local distribution center first and inquire to them about what the problem is and seeing if itвs possible for them to help. If the problem is from your groundwater, it might be best to contact a professional plumber immediately so that they can come and help diagnose the situation at hand.
