Water Smells Like Rotten Eggs in Homestead

Well or water heater? Sort it out

Redland and rural wells

Private wells around Homestead draw untreated Biscayne Aquifer groundwater, and some carry hydrogen sulfide. The smell may come and go with rainfall and pumping. Because sulfur often travels with iron and hardness, treatment is chosen from a full well test. Common approaches include:

• Aeration, which releases the gas from the water before it reaches the house.
• Oxidizing filtration, which converts sulfide so it can be filtered out.

Compare them in aeration vs. filtration for sulfur smells, and see well water treatment in Homestead.

City water and the water heater

HPS Water is chlorinated and stored in elevated towers before it reaches homes. Homestead's 2024 report notes the city increased quarterly odor testing at both plants that year and did not exceed the odor standard; the report attributes odor to naturally occurring organics. So on city water, a true rotten-egg smell usually starts inside the home. Tank water heaters have a sacrificial anode rod, and in some conditions it reacts with bacteria in the warm tank to produce hydrogen sulfide. A licensed plumber or the heater's manufacturer can advise on flushing the tank or switching the anode. A whole-home filter will not fix it, because the smell forms after the filter.

Seasonal and second homes

Homes that sit unused for weeks, including seasonal residences around Homestead, are prone to a smelly first run of hot water. Flushing the heater and running each tap after returning often helps. If it persists, have it checked.
