Although water is essential for our health and well-being, it can also contain dangerous microorganisms which can put us at risk. Bacteria, viruses, protozoa, fungi, pesticides, herbicides and heavy metals can all be found in water, posing potential threats to our health.

Learning about the most common microorganisms that contaminate water, along with the most effective treatments for them, can help you maintain the safety of your facilities and safeguard your business reputation. Read on to discover some of the most common harmful microorganisms found in water.

Bacteria

There are various types of bacteria that can be present in water, including E. coli, Salmonella and Legionella. E. coli (Escherichia coli) is often found in water that’s been contaminated with human or animal waste and can cause severe gastrointestinal illness if it’s ingested.

Salmonella can cause food poisoning-like symptoms, such as diarrhoea, vomiting and abdominal cramps. It is commonly transmitted through water that’s been contaminated with faeces from infected humans or animals. Legionella can cause Legionnaires’ disease, which is a severe form of pneumonia. This bacteria thrives in warm water environments such as hot tubs and cooling towers.

Viruses

Norovirus is a virus which can cause gastroenteritis and is highly contagious. It can spread through contaminated water and surfaces. Hepatitis A is a virus that can cause liver inflammation and can be transmitted through contaminated water and food.

Protozoa

Commonly found in freshwater sources, Giardia is a protozoan parasite that causes giardiasis, an intestinal illness linked to diarrhoea and abdominal pain. Cryptosporidium is another protozoan parasite which can cause gastrointestinal illness. It is resistant to many water disinfection methods.

Other risks in water contamination

Contaminated water poses a wide range of risks beyond the obvious pollutants, including:

Fungal infections: Waterborne fungi, such as Aspergillus and Candida, are often found in contaminated water sources, posing significant health risks. Individuals with compromised immune systems are more susceptible to infections caused by these fungi.

Cyanobacteria toxins: Cyanobacteria, commonly known as blue-green algae, thrive in polluted water, producing toxins which can lead to skin irritation and organ damage.

Chemical contamination from agricultural runoff: The runoff from agricultural activities can cause pesticides and herbicides to make their way into water sources. These chemicals pose a range of health hazards, including hormone disruption, reproductive disorders and increased cancer risk.

Heavy metal contamination: Heavy metals like Lead, Mercury, Arsenic and Cadmium can trickle into water from various industrial sources or corroded pipes. Exposure to these metals over a long period of time can result in severe health complications.

Pharmaceutical compounds: Traces of medications and pharmaceutical compounds can find their way into water through wastewater and runoff. Whilst often unnoticed, these substances can have serious effects on human health and the planet.

Removing contaminants from water

One of the ways that you can remove harmful contaminants from water is by using the reverse osmosis process. This process uses a semi-permeable membrane to remove impurities, including bacteria, viruses and heavy metals, from water.

Pressure is applied, forcing water molecules through the membrane, and leaving behind contaminants that are then flushed away. Reverse osmosis is renowned for producing clean, safe drinking water, making it an increasingly popular choice for both residential and industrial water treatment systems.
