Unseen Water Contaminants: Understanding Biological Pollution's Impact

what is biological pollution of water

Biological pollution of water is caused by pathogens such as bacteria, viruses, protozoa and helminths that are harmful to humans and other forms of life. Infectious diseases caused by biological pollutants, such as typhoid and cholera, are the most common and widespread public health risks associated with drinking water. Viruses, bacteria, and parasites can enter a water supply unknowingly and consumption of this polluted water has serious adverse effects on health.

Pathogens Salmonella, Shigella, Vibrio cholerae and parasites enter water supplies

Pathogens such as Salmonella, Shigella, Vibrio cholerae, and parasites can enter water supplies through contaminated river water and soil that is polluted with human and animal wastes. Infectious diseases caused by biological pollutants are the most common and widespread public health risks associated with drinking water. Viruses, bacteria, and parasites can enter a water supply unknowingly and cause various illnesses.

In the United States, the Environmental Protection Agency (EPA) quantifies and monitors these pathogens in water systems that serve at least 200 consumers. The EPA classifies these contaminants as being microorganisms (even though a biologist might dispute this terminology).

Biological pollutants that constitute a significant part of drinking water contamination can be divided into three categories:

  • Pathogenic microorganisms – Salmonella, Shigella, Vibrio cholerae, viruses, parasites, etc.
  • Chemical pollutants
  • Physical pollutants

Water bodies including lakes, rivers, and ponds are polluted by the wastewater which is released into them due to indefinitely increasing civilization and industrialization. Consumption of this polluted water has serious adverse effects on health.

Infectious diseases like typhoid and cholera are caused by biological pollutants

Biological pollutants are microorganisms (bacteria, viruses, protozoa and helminths) that are harmful to humans and other forms of life. Infectious diseases caused by biological pollutants, such as typhoid and cholera, are the most common and widespread public health risks associated with drinking water. Microorganisms may get into water with dust from the air as rain falls, and when water passes through soil which is polluted with human and animal wastes. The contamination of water supplies with raw sewage (human and domestic wastes generated from residential areas) is the most common route for biological pollutants to enter water. When contaminated river water moves downstream, it is possible that any pollutant will be diluted as more water flows in and so increases the total volume of water in the river.

If water is not cleaned properly, residents of a community can contract various illnesses. Viruses, bacteria, and parasites can enter a water supply unknowingly. All three of these species are pathogenic, or disease-causing. In the United States, the Environmental Protection Agency (EPA) quantifies and monitors these pathogens in water systems that serve at least 200 consumers. The EPA classifies these contaminants as being microorganisms (even though a biologist might dispute this terminology).

Pathogenic microorganisms – Salmonella, Shigella, Vibrio cholerae, viruses, parasites, etc. – are biological pollutants. Looking at the severity of the degree of contamination, health and environmental hazards, it is necessary to decontaminate the water to an acceptable level.

Water bodies including lakes, rivers and ponds are polluted by the wastewater which is released into them due to indefinitely increasing civilization and industrialization. Consumption of this polluted water has serious adverse effects on health. Hence, sewage treatment is a need of the time.
