- Help! My Water Smells Bad
MY WATER SMELLS BAD. WHAT CAN I DO?
You turn on the shower and within seconds, your bathroom smells like a carton of rotten eggs. Or perhaps your glass of water smells like it came straight out of a swimming pool. Water should be clear and odorless, and when it鈥檚 not, it can be concerning. What can you do?
WHAT CAUSES MY WATER TO SMELL BAD?
Chlorine and hydrogen sulfide (aka sulfur) are two chemicals that can cause your water to give off an odor. The causes of bad-smelling water can vary based on where your water comes from. Here鈥檚 how to identify where bad-smelling water is coming from 鈥� and how to fix it.
Municipal Water
Well Water
If your home is supplied by a municipal water facility (city water), the most likely cause of your water smell is coming from something inside your home. City water is treated with disinfectants. Municipalities usually add small, safe amounts of chlorine or chloramine to water to kill germs before they reach your pipes. You鈥檒l know your home is served by a municipal water service if you pay a monthly or quarterly water bill.
Common causes of odors with bad-smelling municipal water:
PUBLIC WATER CHLORINATION
Low levels of chlorine usually go unnoticed, but higher levels may cause an odor. Some people are more sensitive to chlorine than others. According to the Centers for Disease Control and Prevention, 4 milligrams of chlorine per liter of water is safe1. Chances are if it smells like swimming pool water, the chlorine levels are too high.
WATER HEATERS
If the odor is only present in your home鈥檚 hot water, the source may be a magnesium rod in your water heater tank2. These rods are meant to prevent corrosion, but it鈥檚 possible for a chemical reaction to turn water鈥檚 natural sulfates to hydrogen sulfide. If this happens, consider replacing it with an aluminum rod.
A rotten-egg smell is a common issue in well water. You鈥檒l know your home is served by a private well if there鈥檚 a visible well cap on your property or a pressurized tank somewhere in your home. In addition to causes like water heaters or sulfur bacteria in pipes, well water can also produce an odor if your well is drilled in shale or sandstone, or near coal or oil fields2.
