Water is not just a beverage. It’s the essential lifeblood that keeps us alive and well. With this in mind, the quality of the water we consume should be a top priority. In the United Kingdom, water quality varies across regions due to geographical and environmental factors, and the treatment processes employed by different water suppliers. Let’s take a deep dive into the best quality drinking water in the UK.
The Source Matters: Unravelling the Impact of Water Sources on Quality
Water suppliers in the UK mainly source water from two types of sources: surface water (rivers and reservoirs) and groundwater (natural springs and wells) 1. The quality of drinking water is primarily influenced by these sources.
Surface water is generally more exposed to pollutants but is extensively treated to meet quality standards. On the other hand, groundwater tends to be of higher quality as the soil acts as a natural filter, removing impurities. However, it often requires treatment to remove certain naturally occurring substances.
