Many people rely on tap water as their primary source of hydration and household use. However, despite strict regulations on drinking water, there are still potential contaminants that can make their way into the water supply. One such issue is the presence of various organisms and substances that can grow in tap water, posing a risk to human health. In this article, we will explore some of the common things that can be growing in your tap water and what you can do to protect yourself and your family.
- Bacteria
Bacteria are perhaps the most common microorganisms that can grow in tap water. While most bacteria in drinking water are harmless, some can cause illness if ingested. For example, E. coli and Legionella are two types of bacteria that can cause gastrointestinal problems and pneumonia, respectively. In addition, bacteria can cause foul odors and tastes in water.
- Viruses
Although viruses are less common in tap water than bacteria, they can still be present. Norovirus and hepatitis A are two examples of viruses that can be found in contaminated water. While viruses are generally not a significant health risk for those with healthy immune systems, they can pose a serious threat to infants, young children, and individuals with compromised immune systems.
- Algae
Algae are a type of plant-like organism that can grow in tap water. While algae are typically not harmful to human health, they can cause unpleasant tastes and odors in water. In addition, some types of algae can produce toxins that are harmful to humans and animals.
- Fungi
Fungi are another type of organism that can grow in tap water. While most types of fungi are harmless, some can cause infections in humans. For example, Aspergillus is a type of fungi that can cause respiratory infections in individuals with weakened immune systems.
- Protozoa
Protozoa are single-celled organisms that can also grow in tap water. Cryptosporidium and Giardia are two examples of protozoa that can cause gastrointestinal illness in humans. These organisms are typically spread through contaminated water sources, such as lakes and rivers.
- Metals
In addition to living organisms, tap water can also contain various metals that can be harmful to human health. For example, lead and copper can leach into water from plumbing fixtures and pipes, causing health problems if ingested over time. Other metals that can be found in tap water include arsenic, cadmium, and mercury, all of which can be harmful to human health if consumed in high amounts.
- Chlorine
While chlorine is typically added to tap water to kill harmful microorganisms, it can also be harmful to human health if consumed in high amounts. Overexposure to chlorine can cause skin irritation, respiratory problems, and gastrointestinal issues.
