Common Contaminants in Water Coolers

Heterotrophs

Heterotrophs are microorganisms that feed in organic carbon, including yeast, mold, and bacteria. You might be wondering how bacteria end up in the water when the water itself isn’t a food source, right?

Well, bacteria are incredibly resourceful when it comes to using materials as food. For example, once inside your water cooler, certain types of bacteria like Pseudomonas Aeruginosa feed on components found on seals and rubbers within your dispenser.

Heterotrophs can also enter the water cooler when you change the water bottle. Remember, every time you change the water bottle, you expose the surface to the air, which is full of bacteria.

Contaminants can also get into your dispenser if someone touches the internal components.

Chemical Residue

Cleaning your water cooler regularly may rid your water of unsafe microorganisms. However, the cleaning supplies are likely to create problematic issues.

Most cleaning processes include chlorine and bleach. And although the products are highly effective at getting rid of bacteria from your drinking water, they are not safe for human consumption.

This means that you need to ensure that these products are thoroughly flushed through the system and that no residue is left.

Should you dispense water from your cooler and realize that it’s off-tasting or appears cloudy, rinse the dispenser further for your safety.

Algae

The only ingredients that algae need to grow are a damp environment and some sunlight. Actually, under the right circumstances, fluorescent light is enough to make it grow.

Although non-toxic, they impact the smell and flavor of the water.

Illnesses Caused by Contaminated Water Cooler Water

Contaminated water cooler water can pose a health risk to you and your coworkers. So although you might enjoy the convenience these water coolers provide, is it worth the risk?

Germs lurking in the contaminated water might even make you ill.

Species of bacteria that grow in the water can cause several illnesses. For instance, you could contract Legionnaires’ disease, which starts like flu and later progresses to pneumonia.

In the beginning, the symptoms may include aching joints, fatigue, a slight fever, and loss of appetite. This later progresses to a high fever, dry cough, shortness of breath, chills, and chest pains.

Another illness caused by bacteria is Pontiac fever, which produces flu-like symptoms. This fever usually lasts for several days.

Other than these illnesses, you can also contract common colds and viruses from the water cooler, especially if sharing it with many people per day.

The Solution

To avoid bacteria and illnesses surrounding a water cooler, you should ensure proper cleaning and use in your workplace.

Some of the basic rules for the sanitation of the water cooler include:

  • The water cooler should be cleaned every 3 to 6 months.
  • Spray the dispensing taps at least once per week with the appropriate sanitizing agent.
  • Avoid filling water bottles from the tap or any other source.
  • Clean the outside areas of the dispenser and the drip tray regularly.
  • Have your water cooler filters replaced every 6 months.
  • Check the machine regularly to ensure that it’s functioning properly.
  • Only trained should help with the sanitation and maintenance of the water cooler.
