Spartanburg Water Taste & Odor FAQs

Spartanburg Water Taste & Odor FAQs

Why does my water taste or smell “funny?”

Right now, we’re seeing higher levels of a naturally occurring compound called MIB (Methylisoborneol) in our reservoirs. MIB comes from certain types of algae that grow in lakes and rivers—especially during stretches of hot weather and low rainfall. It can create an earthy or musty smell or taste, even though the water is still safe to drink.

What’s causing it?

As the algae naturally grows in the water, it releases MIB. This doesn’t harm the water, but it can make it smell a little like soil, lake water, or a damp basement, and the taste can seem different than usual.

Is the water safe to drink?

Yes. Your water is safe.
We test our water constantly—more than 250 checks every single day—to make sure it meets all state and federal safety standards. MIB can change the taste and smell, but it does not affect the safety, purity, or quality of the water.

If you’d like to learn more, our Water Quality Report is always available on our website.

Is this just happening here?

No. This is a common seasonal issue for many water providers in South Carolina and across the country. Warm temperatures and changing weather patterns can make naturally occurring compounds like MIB more noticeable.

How long will this last?

It’s temporary. Most customers notice the taste or smell for a couple of weeks, although weather, lake conditions, and rainfall can speed it up or slow it down. We’ll continue working to reduce it as quickly as possible.

What is Spartanburg Water doing about it?

We’re actively managing the issue both in the reservoirs and at our treatment facilities. Our teams are:

• Monitoring lake conditions daily
• Adjusting our treatment process in real time
• Using advanced treatment technology, including our Advanced Oxidation System at the R.B. Simms Water Treatment Facility
• Applying treatment in the reservoirs when needed to address the source of the odor

Our certified operators are on it every step of the way.

Is there anything I can do at home?

Yes—chill it!
Keeping drinking water cold in the fridge often makes the taste and smell less noticeable. Some customers also prefer adding a slice of lemon, using a filter pitcher, or letting the water sit before drinking.
