The Environmental Protection Agency (EPA) has identified hundreds of possible contaminants in U.S. drinking water, and residents in Oswego, Yorkville, Naperville, Aurora, and Plainfield are not immune to their effects. One of the most noticeable—and unpleasant—issues is sulfur in water.
What Causes Sulfur in Water?
If your water smells like rotten eggs, you’re likely dealing with hydrogen sulfide gas or sulfur bacteria in your plumbing system or water supply. This distinct smell is a common symptom of sulfur-contaminated well water, where naturally occurring minerals and organic matter interact below ground.
City water systems usually avoid this issue because they are treated with chlorine, which neutralizes sulfur bacteria. However, if you’re on a private well system, you’re more likely to encounter this unpleasant odor and its effects.
Is Sulfur in Water Harmful?
While sulfur bacteria aren’t typically a direct health threat, they can cause other problems. For example, they promote the growth of iron, which can clog plumbing systems and well components. Hydrogen sulfide gas at levels above 100 parts per million (ppm) can be dangerous, even deadly. Most homes with sulfur in water have concentrations between 1–5 ppm—levels that may not be lethal but can still cause:
Headaches
Eye irritation
Fatigue
Digestive issues
Sleep disturbances
Even when not harmful, sulfur-contaminated water is unpleasant to wash, bathe, or clean with due to its strong smell and poor taste.
Other Causes of Bad-Tasting or Smelly Water
Your water may taste or smell bad due to:
Chlorine: Often added during municipal treatment; too much can create a chemical smell and flat taste.
Total Dissolved Solids (TDS): Minerals like calcium and magnesium can make water hard and taste metallic.
Algae and Fungi: These organisms sometimes enter household plumbing and cause earthy or fishy odors.
Heavy Metals: Metals like iron, copper, and zinc can alter water taste and compromise safety.
Bacteria: Bacterial growth in your pipes can create moldy, musty-tasting water.
In northern Illinois, we also deal with hard water. Oswego and neighboring towns commonly report hardness levels exceeding 200 ppm, which can leave white scale buildup and shorten the lifespan of plumbing fixtures and appliances.
How to Treat Sulfur in Water in Oswego and Nearby Areas
If your water smells like rotten eggs or shows signs of contamination, Aquaduct Plumbing Services provides solutions for sulfur in water and other water quality issues.
Whole-House Water Filtration
We install high-performance whole-house water filtration systems that remove sulfur, hydrogen sulfide gas, and other impurities from your water. These systems use granulated activated carbon filters to eliminate:
Hydrogen sulfide (sulfur)
Chlorine
Heavy metals
Algae and bacteria
Total dissolved solids
The result is fresh, clean, better-tasting water for your entire household—without relying on bottled water or point-of-use filters.
Water Conditioning Systems
In addition to filtration, we also offer water conditioners that treat chemically harsh water without softening it. These systems are popular in the Oswego area because they:
Use less water
Require minimal maintenance
Are often more affordable than traditional water softeners
