Why Does My Sarasota Tap Water Smell Like Rotten Eggs?
If your tap water in Sarasota has a rotten egg smell, you’re likely dealing with hydrogen sulfide gas — a byproduct of sulfur-reducing bacteria that occurs naturally in some groundwater supplies throughout Southwest Florida. While generally not dangerous at low concentrations, the rotten egg odor can be an unpleasant odor that’s disruptive, damaging to plumbing systems, and a warning sign of poor water quality in your water supply.
Is Sulfur in Sarasota Water Harmful?
Hydrogen sulfide (H₂S) can impact both your home’s infrastructure and indoor air quality. Though it’s regulated under the EPA’s secondary drinking water standards, focusing on water smell, taste, and appearance, elevated levels of hydrogen sulfide can corrode pipes, stain laundry, degrade water-using appliances, and shorten their lifespan. At higher H2S levels, the gas is flammable and harmful if inhaled over time, especially in homes with poor ventilation or untreated water systems.
What Causes the Rotten Egg Smell in Sarasota Water?
In Sarasota County, sulfur odors in water are most commonly caused by:
Seasonal Water Conditions
During wet seasons or heavy withdrawals, Sarasota’s city water system may carry higher sulfur content, especially in areas like North Port, Cape Coral, and Marco Island.
Naturally Occurring Sulfur Compounds
Sarasota’s source water chemistry, primarily drawn from the Floridan Aquifer, often contains sulfates. When sulfate-reducing bacteria convert these sulfates to hydrogen sulfide, the result is smelly, unpleasant-tasting water.
Water Heater Reactions
If your hot water smells bad, the water tank’s magnesium anode rod may be reacting with sulfates, producing hydrogen sulfide gas molecules.
Local Wells and Septic Systems
Private wells near sewage pollution sources, like septic tanks or organic waste, often produce higher concentrations of hydrogen sulfide and other odor-causing compounds.
Sulfur in Well Water Systems
If your Sarasota home relies on a private well, you’re more likely to encounter elevated sulfur content and persistent rotten egg odor in your tap water. Unlike city water, which undergoes regulated treatment, well water is subject to natural environmental conditions, making it more vulnerable to sulfur-reducing bacteria, decaying organic matter, and mineral-rich groundwater.
Common Sources of Sulfur in Well Water:
- Anaerobic bacteria activity deep in the aquifer
- Sulfates to hydrogen sulfide conversion in stagnant or oxygen-depleted zones
- Contamination from septic systems, landfills, or nearby agricultural runoff
- Hot water lines reacting with sulfur compounds during use
These factors can lead to the buildup of hydrogen sulfide gas, resulting in smelly water, an unpleasant taste, corroded plumbing, and even the discoloration of fixtures. In some cases, hydrogen sulfide levels of 6–8 ppm or higher may be detected, which require immediate treatment.

How Sulfur Affects Your Home and Water Usage
Even at low levels, sulfur in your entire water system can lead to:
- Tarnished metal fixtures and damaged hot and cold water lines
- Black or brown stains in toilets, sinks, and tubs
- Smelly water in showers, laundry, and kitchen use
- Corroded plumbing and reduced appliance performance
- Unpleasant taste and bad taste in cooking or drinking
Identifying the Source of Sulfur Smell in Tap Water
To determine the source of issues in tap water, try the following steps:
- Isolate the Source
Compare a glass of water from the affected tap with one from a different location. If both smell, the problem lies in the water supply. - Test Hot vs. Cold Water
- Odor only with hot water = Issue with water heaters
- Odor with both = Hydrogen sulfide in source water
- Odor only with cold water = Sulfur bacteria in lines
- Conduct a Comprehensive Water Analysis
Consult Culligan Water to perform a comprehensive water analysis. Testing identifies water contaminants, including sulfur, iron, manganese, pH, and total dissolved solids (TDS).
Eliminating the Sulfur Odor: Solutions for Sarasota Homes
If the Problem Is in the Drain
Pour ½ cup household chlorine bleach or 1 cup vinegar with baking soda into the drain. Rinse with hot water to kill bacteria causing the odor of water.
If It’s the Water Heater
- Replace magnesium anode rod with aluminum
- Increase water temperature to 140°F for 48 hours
- Flush heater with chlorine bleach
- Add approved corrosion inhibitors
- Consider regular filter maintenance and a maintenance plan to prevent future issues
If the Problem Is in the Water Supply
Culligan of Sarasota offers advanced water treatment systems and comprehensive solutions for Sulfur Smelly Water Treatments:
- Whole-Home Water Filtration System
Culligan’s Sulfur-Cleer® oxidizes and removes hydrogen sulfide, restoring fresh water and enhanced water quality. It also reduces iron and manganese.
- Reverse Osmosis Systems
Culligan’s Aqua-Cleer® system uses a multi-stage filtration process, including catalytic carbon, to reduce sulfur, chlorine, and other water contaminants. It delivers pristine, great-tasting water and optimal water purity.
What Are Local Water Officials Doing About The Problem?
Sarasota County monitors hydrogen sulfide gas levels, chlorate, and other byproducts like HAA5 to meet safety standards. However, aging infrastructure and source water changes can still lead to hazy water or odors.
Are Sulfur Odors a Health Concern?
Though sulfur’s rotten egg smell helps detect it early, high H2S levels may affect vulnerable individuals. Additionally, smelly water may indicate other water contaminants like barium or nitrate, especially in untreated water systems.
