Foul-smelling or unusual odors from your water should make you question its quality and safety. Some odors indicate the presence of contaminants which may pose a health risk. Other odors, such as those caused by hydrogen sulfide, are more of a nuisance, only affecting the taste of the water.


The presence of sulfur and iron in water, manifesting as a rotten egg odor and rust stains, can have several effects on human health and daily living. Below is a description of how sulfur and iron in water can affect human health:

Sulfur Rotten Egg Odor:

  1. Respiratory Irritation:

    • Hydrogen sulfide gas, which is responsible for the rotten egg odor, can irritate the respiratory system, especially in higher concentrations. It can cause symptoms like shortness of breath, coughing, and sore throat.
  2. Nausea and Discomfort:

    • The unpleasant smell can cause nausea and discomfort, making it difficult for individuals to drink or use the water for cooking and bathing.
  3. Potential Toxicity:

    • In very high concentrations, hydrogen sulfide gas can be toxic, though it is rare for household water supplies to contain such levels.

Rust Iron:

  1. Dietary Iron Overload:

    • While iron is an essential nutrient, excessive iron in drinking water can contribute to dietary iron overload, especially in individuals with hemochromatosis, a condition that leads to excessive iron absorption.
  2. Staining and Damage:

    • Iron in water can stain laundry, dishes, and plumbing fixtures, leading to additional cleaning efforts and potential damage to appliances and surfaces.
  3. Unpleasant Taste:

    • Iron can impart an unpleasant metallic taste to water, making it unpalatable for drinking and cooking.
  4. Bacterial Growth:

    • Iron in water can encourage the growth of iron bacteria, which can form slimy deposits in plumbing and create additional odors.

General Effects:

  1. Skin and Hair Issues:

    • Both sulfur and iron in water can contribute to skin and hair problems. The water may dry out the skin and hair, leading to irritation, itching, and other issues.
  2. Digestive Issues:

    • Drinking water with high sulfur content can potentially lead to mild digestive issues, including diarrhea or stomach discomfort.


While the presence of sulfur and iron in water does not always pose significant health risks, it can cause a range of issues from aesthetic and olfactory concerns to potential health problems. It's essential to address these water quality issues to ensure the water is safe, clean, and pleasant to use for drinking, cooking, and bathing. Utilizing a water filtration system, like the Nelsen Air Injection Oxidizing Filter System, can effectively eliminate these problems, providing you and your family with clean, odor-free, and iron-free water.

 Effects of Sulfur Water

Sulfur in your water supply is easily recognized by its offensive odor. Hydrogen sulfide gas causes the "rotten egg" or sulfur water smell. Hydrogen sulfide in water causes no known health effects. However, high concentrations do change the taste of the water.

Hydrogen sulfide dissolved in water corrodes metals such as iron, steel, copper, and brass. The corrosion of iron and steel from sulfur forms ferrous sulfide or "black water." Hydrogen sulfide in water can blacken silverware and discolor copper and brass utensils.

Sulfur water makes cleaning clothes very difficult. Using chlorine bleach in sulfur water reduces the cleaning power of detergent. Hydrogen sulfide in water also corrodes exposed metal parts in washing machines.

Iron and manganese, often present with hydrogen sulfide, turn the water black and greasy-feeling. If untreated, the water stains laundry, washing machines, sinks and kitchenware. When used in the laundry, chlorine bleach reacts with iron and manganese forming dark rusty or brownish stains on clothes.

 Occurrence & Characteristics

Generally, hydrogen sulfide occurs in concentrations of less than 10 mg/l (milligrams per liter), but occasionally amounts of 50 to 75 mg/l are found. Hydrogen sulfide is more commonly found in ground water supplies than in surface water. Hydrogen sulfide gas quickly escapes from surface water.


Sulfur Aeration Removal Method

Aeration (adding air to the water), by itself, may not always reduce the hydrogen sulfide to non-detectable levels. However, the process sometimes reduces the hydrogen sulfide to acceptable amounts.

An aerator is installed between the well and a non-pressurized water storage tank (Figure 3). A diffuser, cascade, or spray aeration system above the tank aerates the incoming water. The release of the water pressure and exposure to the air removes some of the sulfur compounds. Oxidation removes some of the hydrogen sulfide gas. The process does produce a strong hydrogen sulfide odor near the aerator

Iron Removal Filter Method

An iron removal filter can remove low to moderate amounts (up to around 10 mg/l) of hydrogen sulfide in addition to removing iron and manganese. The filter oxidizes the hydrogen sulfide, converting it into insoluble sulfur which the filtering process then removes.

The filter needs to be regularly recharged with potassium permanganate. The complex recharging process makes the filter system very specialized. The installation and operation instructions of the manufacturer should be followed precisely. Because the precipitated sulfur can clog the filter, the filter needs regular replacement.
