Is There Bacteria

in Your Tap Water?

Each year, more than seven million cases of waterborne infections occur in the United States due to bacteria in tap water. These infections often lead to hospitalizations and, in severe cases, even death, according to the CDC.

The harmful bacteria present in water can cause flu-like symptoms such as diarrhea, nausea, vomiting, cramps, or fever. These illnesses can be particularly severe in vulnerable groups such as children, the elderly, or visitors who are not accustomed to the bacteria.

If you or a family member experience symptoms related to your drinking water, it’s essential to consult a healthcare professional and have your water tested.

What are bacteria?

Bacteria are single-celled living organisms naturally found in the environment that may contaminate drinking water sources. Bacteria levels in well water can vary due to external factors like spring runoff or heavy rainstorms.

Some common bacteria found in well water include:

Total Coliform Bacteria	The presence of total coliform bacteria in a well indicates a potential risk of more severe contamination.
E. coli Bacteria	The detection of E. coli bacteria signals contamination with human or animal waste, posing a more significant health concern.
Iron Bacteria	Iron bacteria are microorganisms that thrive in environments with high levels of iron, leading to the formation of slimy deposits and unpleasant tastes and odors in water sources.
Sulfur Bacteria	Sulfur bacteria, also known as sulfur-reducing bacteria, produce hydrogen sulfide gas, resulting in the characteristic “rotten egg” odor in water and potential corrosion of plumbing fixtures.
Legionella Bacteria	Legionella bacteria are responsible for causing Legionnaires’ disease, a severe form of pneumonia often contracted by inhaling mist or vapor contaminated with the bacteria, commonly found in water systems such as cooling towers and hot tubs.
Pseudomonas Bacteria	Pseudomonas bacteria are opportunistic pathogens that can cause infections in humans, particularly in individuals with weakened immune systems, often found in water sources and can lead to skin, ear, and eye infections.

What are the signs of bacterial contamination?

Signs of bacterial contamination may include unusual staining around fixtures and drains, a foul smell (like rotten eggs or mold), or cloudy or discolored water.

If you notice any of these signs, stop using the water immediately and have it tested.

How do I treat bacteria in tap water?

Some private well owners use chemical treatments to “shock” their wells when bacteria is detected. However, this is only a temporary solution.

A highly effective alternative is a UV light sterilizer, which can treat water throughout your entire home without the use of chemicals.
