When it comes to drinking water, one of the most common question is – is my water safe to drink?
In fact, this is one of the biggest concerns for travellers, NGOs and disaster relief agencies that are operating overseas. Therefore, it is so important to know what is inside your water especially when you are travelling overseas. The Dangers of Harmful Contaminants in Water
Drinking water can expose you to a variety of harmful biological, chemical and physical contaminants which can make you very sick. In fact, a report by the World Health Organization (WHO) shows that the consumption of contaminated drinking water is estimated to cause 50,200 diarrhoeal deaths each year.
Before we decide whether the water is safe to drink, let’s go through some water fundamentals. Here are the six most common contaminants present in water.
Bacteria

Bacterial contamination is the single most common threat to drinking water, and its impacts are disabling, quick and potentially deadly.
Many waterborne bacteria are categorized as pathogens (disease causing microorganism) and they could lead to diseases, like salmonellosis, typhoid fever, and cholera. One of the most commonly found bacteria in untreated water sources such as rivers and lakes include E.coli (Escherichia coli), a faecal coliform present in human and animal waste. Drinking such contaminated water can cause vomiting, diarrhoea as well as ear, respiratory, eye, or skin problems. Protozoa

Giardia and Cryptosporidium are common harmful water protozoa which cause waterborne diseases. It is usually found in water with a high level of fecal pollution. Although many other protozoa are harmless to humans, they can contribute unpleasant odor to the water.
Most protozoa form protective cysts to survive in unfavorable environmental condition. They are resistant to chlorination, a common disinfection method. Hence, it is really hard to get rid of protozoa in water. The ROAMfilter™ Plus is very effective in removing bacteria and protozoa from the water, making it an ideal solution for tackling these contaminants. Virus

Virus is the tiniest biological pathogen you can find in water. Despite its size, it accounts for numerous cases of severe diarrhoea and deaths in children across the globe. An infected person may show symptoms such as jaundice, dark urine, loss of appetite, nausea, vomiting, and fever.
In severe cases, it may lead to liver failure and even death. Viruses are smaller than bacteria and protozoa in size, making detection harder with standard water testing and difficult to be removed. Inorganic chemical

Inorganic chemical refers to those compounds with a chemical structure without carbon, such as heavy metals and nitrate. Heavy metals can be naturally occurring or can be released by human activities.
In trace amounts, certain heavy metals such as copper, selenium, and zinc are essential to maintain the metabolism of the human body. However, elements such as arsenic, lead, and mercury are harmful to the body even in small concentration. At a high concentration, heavy metals are poisonous to the body and chronic exposure can damage the human body indefinitely. Certain heavy metals can accumulate in the body and the effects can cause in-borne deformities in children. Click here for more information on heavy metals.

Organic chemical

Organic chemical includes compounds with a chemical structure which consist of carbon. They include proteins, plastic, petroleum compounds, pesticides, herbicides, and chlorinated-carbon compounds. They are found in water sources and are typically caused by human activities, such as improper disposal of solvents and petrochemicals.
The main concerns of organic chemicals are those that are non-volatile as they are unable to be removed by simply boiling or aeration. Certain organic chemicals are toxic and could cause adverse health effects when consumed. The exposure risk is determined based on the individual constituents of the organic chemicals, with each having the potential to trigger different human health effects, symptoms, or illnesses. Suspended Solids
Suspended solids refer to the small solid particles which remain suspended in water. The suspended solids may not be dangerous in itself, but pathogens can potentially adhere and be carried on the surface of the particles. High level of suspended solids in water is often associated with the presence of biological contaminants.
Suspended solids could also affect and reduce the efficiency of several water treatment method, such as ultraviolet disinfection, boiling, or chemicals. How do I determine my water quality?
At the end of the day, knowing the constituents in your drinking water is the first step in ensuring that your water is safe to drink.
You can test the quality of your water using a laboratory or a portable water test kit. If you are travelling in remote areas such as disaster zones or rural areas, consider using our Water Test Kits to ensure that your water is safe to drink. Buy a portable test kit now for your next adventure!
Did you know, 525,000 children under 5 die from diarrhoeal diseases every year? Millions more fall ill due to water-borne diseases caused by the lack of access to clean drinking water.

If you’re reading this blog post, you’ve been part of our journey to end prolonged thirst. And that is Awesome. Did you know that since our inception in 2014, we’ve been able to provide 72,000 people across 28 countries with better access to safe drinking water? To our Champions, Partners and Sponsors, a BIG THANK YOU to you – we’d never be able to achieve this without you. 
But right now, there is still 2 Billion people in the world living without clean water. That’s 2 in 7 globally. Scary, isn’t it. So – why are we still doing this? Why Water? For people living in rural regions and disaster zones, safe drinking water can change everything. Cleaner and safer drinking water means better healthier families, more productive parents and kids learning at school. And if that’s not enough of a reason, you get a smile like hers that will 100% brighten up your day.
