Homeowners appreciate well water because it is reliable, clean, and contains healthy minerals. However, at some point, you may notice that the water is developing a strange odor. This smell may indicate several issues that require professional attention. Below are three causes of foul scents coming from your well water.

3 Potential Causes of Well Water Odor

1. Increased Buildup in the Pipes

Well water contains minerals like calcium, magnesium, and sodium. These materials can build up inside the pipes, potentially causing a foul odor. If you notice a bad odor in just one faucet, this may be the culprit. A plumber can clean out the pipe and ensure that minerals are the cause of the issue while checking that rust and corrosion aren’t at play. 

2. Higher Sulfur Bacteria Content 

If the scent smells like rotten eggs, it’s likely related to a buildup of sulfur bacteria. The naturally occurring bacteria grow into slime inside the pipes, water softeners, water heaters, and wells. Typically, the presence of sulfur bacteria doesn’t affect whether the water is safe to drink, even though it carries an unpleasant smell.

If the odor is not present when using the cold side of the faucet, the water heater may need attention. If the smell goes away after running the tap for several minutes, it may be caused by groundwater or the plumbing system.

Have a well water inspection team assess all of the above and offer solutions. They may replace the magnesium anode in the water heater after flushing and disinfecting it. They might also disinfect and scrub the well to remove any slime there.

3. Organic Matter in the Drain

Many kitchens give off odors from the sink drain. This smell may grow stronger if you’re using hot water, as the heat and pressure brushing across the drain will give off a stench. Be sure to scrub the drain regularly and pour vinegar or boiling water into it to break up any built-up food matter. Never pour grease, fat, or oil into the drain as it is likely to contribute to an unpleasant smell. The materials can also potentially clog the pipes as they solidify.
