Causes of bacteria in drinking water

Sewage Contamination

Sewage contamination is one of the most common causes of bacteria in drinking water. When sewage or septic tanks overflow, it can contaminate the surrounding water sources with bacteria, viruses, and parasites, making it dangerous for human consumption.

Animal Waste

Animal waste, whether from livestock or wild animals, can also significantly contribute to bacteria in drinking water. As water runs through contaminated soil or bodies polluted with animal waste, the bacteria can find their way into drinking water sources.


Cross-contamination can occur when the pipes and storage tanks used to transport drinking water come into contact with contaminated water. This can occur during repairs or maintenance and, if not adequately disinfected, can cause bacterial contamination.

Poor Sanitation

Poor sanitation practices, such as not washing hands, not washing utensils, and improper food preparation, can also result in bacteria in drinking water. In addition, when people use contaminated water, they can introduce harmful bacteria into the water system and spread it to others.

Inadequate Treatment

Sometimes, water treatment systems can fail to remove bacteria and other contaminants from the water adequately. This can occur due to insufficient treatment processes, malfunctioning equipment, or inadequate filtration systems.

Agricultural Runoff

Agricultural runoff accounts for a significant amount of bacterial contamination in drinking water. When agricultural waste and pesticides enter water sources, they can carry bacteria and other harmful contaminants, polluting the water.

Natural Contamination

Natural sources of bacteria, such as algae and bacteria in soil and vegetation, can also end up in drinking water sources. While not as common as other causes, natural contamination can still pose a risk to human health if not treated properly.

Get rid of bacteria in your drinking water

Access to safe and clean drinking water is essential for maintaining good health. However, untreated or improperly treated water can be a source of harmful bacteria and other pathogens, leading to various waterborne illnesses.

To ensure the safety of your drinking water, it is necessary to take appropriate measures to remove bacteria and other contaminants. This article will discuss various methods to remove bacteria from drinking water and improve its quality.

Boiling water

Boiling water is a simple and effective way to remove bacteria. To do this, bring water to a rolling boil for at least one minute. This kills most bacteria and other pathogens, such as viruses and parasites.

Water filters and purifiers

Water filters and cleaners are designed to remove bacteria and other impurities from drinking water. Various options are available on the market, ranging from simple carbon filters to reverse osmosis systems.


Chlorination is a common method used by municipalities to disinfect drinking water supplies. Chlorine kills bacteria, viruses, and other pathogens, making drinking water safe. Chlorination is highly effective and is used by water treatment plants worldwide.

Ultraviolet (UV) light

UV light is another method used to disinfect water. This method works by exposing water to UV light, which kills bacteria, viruses, and other pathogens. UV light systems are used in residential and commercial applications to improve drinking water safety.


Distillation is a process that involves heating water to create steam, which is then collected and condensed back into the water. This method kills bacteria and other pathogens by boiling the water and separating it from its impurities, making it safe to drink.
