Is the water safe to drink?
Water is a vital element without which humans cannot live. The question of whether water is safe to drink is complex and depends on many factors such as the source of the water, its treatment and possible contaminants. In this article, we look at the factors that affect the potability of water and how you can ensure that the water you drink is safe.
Water sources
The potability of water primarily depends on its source. The most common sources of water are:
- Tap water
- Well water
- Surface water (lakes, rivers, streams)
- Bottled water
Tap water
In Finland, tap water is usually of very high quality and safe to drink. Water utilities treat and purify water before it reaches households. The processing process includes, among other things:
- Filtering
- Chemical treatment (e.g. chlorine or ozone)
- UV disinfection
However, the quality of tap water is also affected by local conditions and possible plumbing problems. It is recommended to check the bulletins and water quality reports of the water authority in your area.
Well water
Well water can be drinkable, but its quality varies greatly. The quality of well water is affected by, among other things:
- Position and depth of the well
- Soil quality
- Potential pollution (e.g. fertilizers, waste water)
It is recommended to test well water regularly in a laboratory to ensure its suitability for drinking.
Surface water
Surface water, such as water from lakes, rivers and streams, is usually not immediately potable without treatment. Surface water may contain:
- Bacteria and viruses
- Parasites
- Chemical pollution
The potability of surface water can be ensured by boiling the water or using water purification tablets or filters.
Bottled water
Bottled water is generally safe to drink, but its quality can vary depending on the manufacturer. It is important to check the bottle label and make sure the water is from a reliable source. The use of bottled water is also environmentally questionable, as plastic bottles cause waste.
Summary
The potability of water depends on many factors, such as the source and treatment of the water. In Finland, tap water is generally safe to drink, but well and surface water often require additional treatment. Bottled water is also an option, but its use should be considered due to the environmental impact. It is always good to check the water quality and use water purification methods if necessary.
