In rural areas, well water is one of the most common water sources. It’s common knowledfe that well water can have a lot of minerals in it. However, it can sometimes be marked by a bad smell similar to hard boiled eggs and sulfur, which can be concerning. Well water that smells like sulfur can be fixed. You can learn what causes the smell and what kinds of problems it may cause.
The Science Behind Sulfur Smell in Well Water
Sulfur Compounds
The formation of a bad smell in well water is mainly attributed to the production of hydrogen sulfide gas (H₂S). Hydrogen sulfide combined with water may cause production of other sulfur compounds that can cause this smell.
Sources of Hydrogen Sulfide
1. Natural Geology: The main thing that makes hydrogen sulfide pollute well water is that it forms naturally in the rock. Materials such as shale, limestone, and coal beds are known to contain this substance naturally. When water flows through this formation it takes hydrogen sulfide gas along with it into the well.
2. Decomposition of Organic Material: Occasionally, the breakdown of organic material in the ground or surrounding earth layers of the well can lead to the formation of hydrogen sulfide. This is common in the areas with a high content of organic material or where the water table is very dynamic.
3. Corrosion of Well Components: Pipeline and well casing products, which are made of iron or steel, are usually exposed to corrosion which can also lead to the formation of hydrogen sulfide gas; the latter dissolves in water when it is acting as a solvent.
Health Implications of Sulfur Scented Water
Although hydrogen sulfide in water is not dangerous at certain concentrations, at elevated concentrations it is toxic to the body.
Here are some considerations:
Health Effects
Low Levels: At low concentrations, the effects of hydrogen sulfide are mostly considered an inconvenience as it has an unpleasant odor and taste. It is not particularly dangerous to human health and is safe for consumption in drinking.
High Levels: Higher concentration of the H2S may cause eye, respiratory, and gastrointestinal irritation of the human body system. If you think that your well contains high concentrations, you should have it tested.
Safety Precautions
It is important to have regular water tests from the well in order to identify whether it has high H2S levels or not. If high levels are present, it is prudent to seek advice from water purification specialists or the local health departments.
Identifying and Diagnosing the Problem
Water Testing
The first thing that should be done regarding well water that smells like sulfur is to take a water sample for analysis.
This test should include:
Hydrogen Sulfide Level: Check the hydrogen sulfide concentration to know if it poses a danger to people in the area.
pH Levels: Since sulfur is highly acidic, this increases the smell and causes corrosion.
Iron and Manganese: These metals may be in the form of rust and also may cause a water quality problem.
Visual and Olfactory Clues
Cloudy: Water may be cloudy because of grit or discoloration, which is usually caused by iron or manganese.
Intermittent Smell: Hydrogen sulfide is usually present in water that has a strong sulfur smell that can be noticed even after leaving the water to stand for a while.
Solutions for Well Water that Smells Like Sulfur
Water Treatment Options
1. Activated Carbon Filters: These filters eradicate hydrogen sulfide from water and usually have the potential to eliminate the negative smell and taste of the water.
2. Oxidation Filters: This filter converts the hydrogen sulfide into elemental sulfur which is slightly soluble and can be easily removed through filtration. This common option includes chlorine, ozone, or manganese greensand option.
3. Point-of-Use Treatment: You can use point-of-use treatment in the sink or any other area where the water is most exposed.
When to Seek Professional Help
You should get help from a water treatment professional if the water has a lot of hydrogen sulfide or if you need more information about how to mitigate this problem with your well water. Well water specialists can help you reach your goal and improve your source of water.
