Signs of Bacteria & Viruses in Your Water

Have you ever become ill after drinking tap water? Waterborne bacteria and viruses may be the culprit. According to the Centers for Disease Control and Prevention, there could be as many as 12 million cases of waterborne acute gastrointestinal illness annually in the United States. These illnesses are frequently caused by bacteria, viruses, and protozoa that make their way into the water supply.

How Bacteria & Viruses Enter Your Water Supply

City Water

City water tends to be treated for bacteria. If you’re connected to public water, you may have received a boil water advisory, which local health officials will send out when there’s evidence that the water supply may be contaminated. If you frequently receive boil water advisories, installing a water filter designed to neutralize bacteria and viruses will ensure your water remains safe.

Well Water & Rural Water

Wells and rural water systems are more susceptible to bacterial outbreaks. Since bacteria like coliform thrive in feces, they’re a common problem in rural water systems and agricultural water supplies. A water test can reveal whether viruses or bacteria are present in your water. If the results are positive, a CUV system can be used to disinfect pathogens in your water using ultraviolet light.

Which Bacteria & Viruses Can Spread Through Tap Water?

E. Coli

E. coli, part of the larger group of bacteria known as coliform, causes severe stomach cramps, vomiting, and diarrhea. It can even lead to death if untreated.

Giardia

Giardia is a parasite present in feces that can spread through water, food, and surfaces, causing diarrhea and stomach pain.

Noroviruses

One of the leading causes of waterborne disease outbreaks, norovirus causes vomiting, diarrhea, and stomach cramps.

Removing Viruses & Bacteria from Your Water

Most water filters that you attach to your sink nozzle, or that may be in your refrigerator, are not effective against germs. To ensure your water is safe to drink, you need a filtration system specifically designed to neutralize bacteria and viruses. Our experts can test your water and recommend the right water treatment system for you.

Frequently Asked Questions

Yes. Well water should be tested for bacteria at least once a year. Unlike municipal water, private well owners are responsible for monitoring their own water quality.

Beyond annual testing, you should also test anytime you notice a change in taste or odor, after heavy rainfall or flooding near your well, following any well service or pump replacement, or if someone in your household has a weakened immune system. Regular well water bacteria testing is the best way to catch problems early, before they affect your health.
Biological contamination usually has no visible signs. Water can look, smell, and taste completely normal and still contain harmful microorganisms.

The most common warning sign is illness, especially recurring gastrointestinal symptoms like stomach cramps, nausea, vomiting, or diarrhea after drinking tap water. If multiple people in your household experience similar symptoms, or if there’s been a boil water advisory in your area, testing is strongly recommended.
Yes. Treating biological contamination is not always a one-time fix. A UV disinfection system works continuously, neutralizing bacteria and viruses as water flows through it, but it does not eliminate the source of contamination.

If your well casing is compromised, if there’s agricultural runoff nearby, or if a septic system is failing, new contaminants can continue to enter your water supply. Annual testing is still important to confirm your system is working properly and that your water remains safe.
No. Common household filters like pitcher filters, faucet attachments, and refrigerator filters are not designed to remove biological contaminants. While they may improve taste or reduce certain chemicals, they do not reliably eliminate bacteria, viruses, or protozoa and can create a false sense of security.

To properly address biological contamination, you need a water treatment system specifically designed for pathogen control. UV disinfection systems are one of the most effective options, using ultraviolet light to neutralize microorganisms without adding chemicals or changing the taste of your water.
There is no reliable way to confirm that your water is biologically safe without testing. Visual appearance, taste, and odor are not dependable indicators. Contaminated water can look and taste completely normal.

A professional water test is the only way to know for certain. Testing typically starts with coliform bacteria, which serve as a broad indicator of potential contamination. From there, additional testing can screen for E. coli, protozoa, and other pathogens based on your water source and local risk factors.

If contamination is detected, the test results will help determine which treatment system is the right fit for your specific situation, rather than you guessing at a solution before you know what you’re dealing with.
