Water is essential to our lives, and it’s no surprise that we need to drink it regularly to stay healthy. However, not all water is safe to drink, and it can be tricky to know which sources are trustworthy. So, how do you know if water is safe to drink?
First of all, it’s important to note that even clean-looking water can be dangerous. Bacteria, viruses, and other harmful substances can be invisible to the naked eye. To ensure your water is safe, you must test it in a lab. Your local health department can provide information on how you can get your water tested, and the results will tell you if the water is safe to drink or not.
Another way to tell if water is safe to drink is by observing its source. If it comes from a well or public water system that meets health standards, it’s generally safe to drink. However, water from lakes, rivers, and streams can be risky because it may have been contaminated by animal waste or chemicals. Always make sure to research the source and check with local health authorities before drinking any water from these sources.
Different Sources of Drinking Water
Water is an essential element in human life and drinking clean water is necessary for survival. However, not all water sources are safe for drinking. Here are the different sources of drinking water:
- Tap water – This is the most common source of drinking water and comes from the municipal water system. Water goes through a treatment process that removes bacteria, viruses, and other contaminants before it is distributed to homes and businesses. However, tap water can still contain trace amounts of contaminants, including lead, chlorine byproducts, and pharmaceuticals.
- Well water – Water from underground sources can be accessed through a well. This source of water is not treated by the municipal water system, and it is the responsibility of the homeowner to ensure that the well water is safe for drinking. Well water may contain natural contaminants, such as arsenic, radon, and E. coli bacteria, and homeowners should have their water tested regularly.
- Bottled water – Bottled water comes from various sources, including spring water, purified water, and mineral water. Bottled water manufacturers are required to meet the same safety standards as municipal water systems, but bottled water can be expensive and environmentally unfriendly due to the use of plastic bottles.
- Rainwater – Harvesting rainwater for drinking is an alternative source of water for those who live in areas with limited access to clean drinking water. Rainwater is naturally clean, but it can become contaminated if it comes into contact with roofing materials or if it is stored in dirty containers.
It is essential to know the source of your drinking water and to have it tested regularly to ensure its safety. The table below shows some common contaminants found in drinking water and their potential health effects:

While boiling can be effective at making water safe to drink, it may not remove other impurities or contaminants present in the water.
Reverse Osmosis
Reverse osmosis is a water treatment method that involves passing water through a semi-permeable membrane to remove impurities and contaminants. During reverse osmosis, water is forced through the membrane, which traps pollutants and allows clean water to pass through. This method is effective at removing many types of impurities, including minerals, chemicals, and heavy metals. However, reverse osmosis may not be effective at removing volatile organic compounds (VOCs) or bacteria and viruses that may be present in the water.
| Impurities that can be removed using Reverse Osmosis | Impurities that may not be removed using Reverse Osmosis |
|---|---|
| Minerals (e.g. lead, calcium, arsenic) | Bacteria and viruses |
| Chemicals (e.g. chlorine, fluoride) | Volatile Organic Compounds (VOCs) |
| Heavy metals (e.g. mercury, copper) |
Before choosing a water treatment method, it’s important to consider the specific impurities and contaminants that may be present in your water, as well as your individual needs and preferences.
