How to Remove Viruses From Drinking Water?

by Web tech - Updated February 24, 2025
Water is essential for life, and clean drinking water is fundamental to human health. Unfortunately, contaminated water can contain a wide range of pathogens, including viruses. These microscopic organisms can lead to various diseases and health complications, making it imperative to understand how to remove viruses from drinking water.
This blog will explore effective methods to eliminate viruses from water, explain the types of viruses that may be present, and delve into common questions like "Are viruses alive?" and "What is the viruses’ impact factor on health?"

Types of Viruses Found in Drinking Water

Waterborne viruses are often spread through human or animal waste and can contaminate water supplies when they come into contact with untreated sewage, agricultural runoff, or poorly managed waste disposal systems. While many of these viruses are uncommon, they can still pose a significant threat, especially in developing countries or areas with inadequate water sanitation systems. Some of the most common viruses found in drinking water include:

Enteric Viruses

Enteric viruses are a group of viruses that affect the intestines and are primarily transmitted through contaminated water or food. The most notable enteric viruses found in drinking water are:
  • Norovirus : This highly contagious virus is one of the leading causes of gastroenteritis worldwide. Symptoms include vomiting, diarrhea, and stomach cramps.
  • Rotavirus : Primarily affecting children, rotavirus can lead to severe dehydration and diarrhea.
  • Hepatitis A : This virus targets the liver and can cause symptoms like jaundice, fatigue, and stomach pain.

Adenoviruses

Adenoviruses are another common type of virus that can cause respiratory and gastrointestinal issues. While adenoviruses are less commonly associated with waterborne outbreaks, they can still be present in contaminated water.

Are Viruses Alive?

A common question that arises when discussing viruses is whether they are considered "alive." Technically, viruses are not classified as living organisms in the traditional sense. Unlike bacteria or fungi, viruses do not have the cellular machinery to reproduce on their own. Instead, they rely on the cells of a host organism to replicate. While they can remain dormant outside a host, viruses become "active" only when they infect a host cell, hijacking its machinery to reproduce.
Despite this, viruses are still a significant concern in public health due to their ability to cause disease and spread rapidly among populations.

Viruses’ Impact on Human Health

The presence of viruses in drinking water poses a substantial risk to human health. The impact of waterborne viruses depends on several factors, such as the type of virus, the concentration of contamination, and the health of the individuals exposed. Here are some key considerations regarding viruses’ impact on human health.

Infectious Diseases

Viruses in drinking water can lead to gastrointestinal, respiratory, and even neurological diseases. For example, enteric viruses like norovirus and rotavirus cause nausea, vomiting, and diarrhea, which can result in severe dehydration, especially in vulnerable populations such as young children and the elderly.

Outbreaks and Epidemics

Waterborne viral infections can cause localized outbreaks or even large-scale epidemics, particularly in areas with inadequate sanitation or during natural disasters. For example, contaminated water supplies during flooding or other crises can lead to widespread outbreaks of diseases like hepatitis A.

Long-Term Health Risks

While most viruses in drinking water cause short-term illness, some, such as hepatitis A, can cause long-term liver damage if not properly treated. Chronic viral infections can result in serious health issues, including liver failure, long-term fatigue, and even death.

Methods to Remove Viruses from Drinking Water

Fortunately, there are several ways to remove viruses from drinking water. Depending on the severity of the contamination and the available resources, different methods may be appropriate.

Boiling Water

Boiling is an effective, simple, and affordable method to eliminate viruses, bacteria, and parasites from water by denaturing their proteins. However, it requires a heat source, is impractical for large quantities. Additionally, boiling doesn’t remove chemical contaminants like heavy metals or pesticides.

Reverse Osmosis (RO) Filters

Reverse osmosis water filters utilize a semi-permeable membrane to remove particles as small as viruses, making them highly effective at purifying water. They can effectively reduce a wide range of contaminants, including bacteria, viruses, heavy metals, chlorine, and other harmful substances. This filtration process ensures that the water is safe to drink by reducing both microbial and chemical impurities, providing high-quality, clean water.

Ultraviolet (UV) Purification Systems

UV light purification systems use ultraviolet light to destroy the DNA or RNA of viruses, rendering them unable to reproduce. UV water purifiers are effective against a broad range of viruses but require the water to be relatively clear to work optimally.

Activated Carbon Filters

While activated carbon filters are excellent for removing chlorine, volatile organic compounds (VOCs), and other impurities, they are generally not effective at removing viruses. To remove viruses, an activated carbon filter would need to be combined with a UV or reverse osmosis system.

Distillation

Distillation is a highly effective method for removing viruses and other contaminants from water. It works by boiling water and then condensing the steam back into liquid form, effectively separating water from most impurities, including viruses. While it is highly effective and doesn’t require chemicals, distillation is energy-intensive, time-consuming, and not practical for large-scale water purification.

Conclusion

Viruses in drinking water are a serious health risk that can lead to infectious diseases, outbreaks, and long-term health complications. Understanding the types of viruses that may contaminate water and knowing how to reduce them is essential for maintaining good health. Whether through boiling, filtration systems , or distillation, there are various methods available to ensure safe, clean drinking water.
If you’re concerned about the quality of your water, it’s essential to invest in proper water treatment and purification systems, especially if you live in an area with poor sanitation or unreliable water supplies. Protecting yourself and your family from waterborne viruses is an investment in health and well-being.
