Why does my well water smell like sewage, and how do I fix it?

Three things cause water to smell bad:

Three things cause water to smell bad: bacteria, mold, and chemicals.

Bacteria produce a strong ammonia smell when it breaks down organic matter in the well. This can result from wastewater seeping into the well through cracks or damaged pipes.

Call your local sewage treatment facility to resolve this issue and ask them to inspect your system. Also, make sure you're not pumping your septic tank too frequently; this will only add more excess waste into the groundwater that flows into your well.

Mold thrives on moisture, so if there's any standing water near where you tap into your healthy, that could be causing an unpleasant scent as well. It's essential to keep gutters clean, so they don't clog up with debris that would prevent drainage from reaching downspouts (which then lead directly to wells).

You should also check for leaks inside or around your house because even small amounts of trapped moisture can be enough for mold growth over time—and one area where mold tends to develop is under sinks.

What causes dirty sock syndrome?

Dirty sock syndrome is a widespread problem with well water. It's caused by the presence of methane gas, sulfur, ammonia, hydrogen sulfide, and iron in your well.

Hydrogen sulfide comes from waste material that enters your well when it rains or snow melts. Iron bacteria turn this waste into iron sludge that can build up at the bottom of your suitable casing and clog it up.

What causes a rotten egg odor?

Hydrogen sulfide gas is a toxic byproduct of bacteria that breaks down organic material in anaerobic conditions (i.e., without oxygen). It smells like rotten eggs and can be found in well water, municipal water supplies, surface water, and groundwater.

How can I fix dirty sock syndrome in my well?

Dirty sock syndrome can be painful, but there are ways to treat it. Here are some options for you to consider:

  • A water softener and filter will help remove unwanted minerals from your healthy water, which is a common cause of dirty sock syndrome.
  • A water conditioner adds chemicals that soften your water, make it smell better, and increase pH levels (which helps fight against sulfur smells).
  • A reverse osmosis system removes salts in addition to other contaminants found in well water (like bacteria). You'll need one if you have hard or mineralized water that smells bad after running through the pipes for a while—like when you turn on your faucet at home.
  • A distiller heats up dirty liquid until evaporation occurs; this process repeats itself until only clean air remains without any contaminants whatsoever. This method also works well with other types of pollution like mold spores floating around in the air such as during rainy seasons."

How can I fix a rotten egg odor in my well?

If your well is properly constructed, the source of a rotten egg odor in your water may be an issue with the pump or piping. You'll first want to ensure that everything is turned off and then check for leaks by looking for wet spots around your well.

Next, check pressure levels by running water from a garden hose into a bucket until it's complete and then back flushing through empty pipes until it runs clear again—if there are any leaks present, this will help find them.

If there are no leaks visible outside of your house (or if these steps didn't help), there could still be some issues with components inside your home—like an old cap or worn gaskets on faucets—that could cause similar problems.

Let's get started--what do you need to identify the source of the problem?

First and foremost, you'll need to test your water. To do this, you'll need to take a sample of your water and send it off for testing.

The lab will be able to tell you what kind of bacteria are present in the water, if there are any coliforms present, and if they can be treated with chlorine or another disinfectant.

Where should you take the sample? Most labs recommend taking it from a clean part of the well where there is no buildup at all--ideally on top of the casing (the pipe that goes down into the ground) or right before entering into this area so that any contamination can be easily identified.

How do we take our samples? For most tests, we'll use a clean jar or jug full of tap water straight from our faucet (making sure not to include any sediment).

Then we fill out some information about ourselves and how often we've been having issues with our well water, why we decided to get tested, etcetera.

Once everything has been filled out correctly and sealed properly by hand--and making sure no one else has touched anything--it can be shipped off for analysis at labs across America.

If your healthy water is making you sick, you should seek medical advice and start treating your water ASAP.

If your healthy water makes you sick, it's essential to seek medical advice. You may need antibiotics or other medications to treat the illness.

If your well water smells like sewage, it's essential to seek medical advice and start treating your water ASAP. It may be that the smell is, in fact, caused by sewage leaking into the ground near your home—something we'll discuss more below.

Watch why does my well water smell like sewage, and how do I fix it?

What makes my well water smell like sewage, and how do I fix it? (FAQs)

What causes the smell of sewage in well water?

There are a few potential causes of a sewage smell in well water. One possibility is that the well water is contaminated with sewage.

This could happen if the well is located near a septic tank or sewage treatment plant or if there is a crack in the suitable casing that allows sewage to enter the water. 

Another possibility is that the well water is not contaminated with sewage but contains high levels of naturally occurring sulfur. This can give the water a sewage-like smell.

Finally, the well could be located near a source of methane gas, which can also provide the water with a sewage-like smell.

What are the benefits of using a water treatment system?

There are many benefits to using a water treatment system. The most obvious benefit is improving your water quality, making it safer and more pleasant to drink.

Treatment systems can also remove harmful contaminants from your water, making it safer for cooking and cleaning. In addition, a good water treatment system can prolong the life of your plumbing fixtures and appliances by preventing the build-up of scale and corrosion.

Finally, a water treatment system can save money by reducing your water and sewer bills.

Do I need to replace my good pump if my water smells like sewage?

If your water smells like sewage, it is probably because there is a problem with your good pump. Replacing your good pump is the best way to solve this problem.

Is there anything else I can do to get rid of the smell of sewage or prevent it from coming back?

Some things can be done to eliminate the smell of sewage or prevent it from returning.

First, ensure that your septic tank is adequately maintained and pumped on a regular basis. If you have a city sewer, contact your local utility company to have them clean the main sewer line.

You can also pour a cup of bleach down your drains once a week to help keep them clean and free of odor-causing bacteria.

Do I need to clean my water tank/reservoir?

If you have a water tank or reservoir, it's essential to keep it clean to ensure that the water inside is safe to drink. There are a few different ways to clean your water tank; the best method will depend on the size and type of tank you have.

If you have a small tank, you can clean it with a brush and some disinfectant. For larger tanks, you may need to hire a professional to clean them for you. In either case, cleaning your water tank at least once a year is essential to prevent the build-up of bacteria and other contaminants.

Is it safe to drink the water if it smells like sewage?

No, drinking the water is unsafe if it smells like sewage. Sewage can contain harmful bacteria and viruses that can cause serious illness.

If you come into contact with sewage, you should wash your hands thoroughly with soap and water. If you have ingested sewage, you should seek medical attention immediately.

Why is my water pressure dropping?

A few factors could explain why your water pressure might be dropping. Possible causes include leaks in your pipes. This can happen if a pipe burst or a joint starts loosening.

Another option is that there is an issue with your water pump. If the pump isn't working correctly, it can cause the water pressure to drop.

Additionally, if there is sediment build-up in your pipes, that can also lead to lower water pressure.

Can I tell whether I have a well or a septic tank?

There are a few ways to determine whether you have a well or a septic tank. If you have a private water source, chances are you have a well. Check your water bill to see if you are being charged for water usage.

If you are not, then you most likely have a septic tank. Another way to tell is to look at your property. If you have a septic tank, you will usually have a small shed or outhouse on your property.

This is where the septic tank is located. If you are not sure, you can always contact your local municipality to find out for sure.


Now that you know what your water might be contaminated with, it's time to do something about it. If your healthy water is making you sick, you should seek medical advice and start treating your water ASAP.
