Purified water undergoes a filtration or purification process to remove impurities including bacteria, algae, fungi, and parasites, metals like copper and lead, and chemical pollutants. It is usually produced using groundwater or tap water. While tap water is safe to drink in many areas, it may still contain trace contaminants. Heavy metals such as lead and copper can leach into drinking water and can cause harm to your health. By using water purification systems like Urban Streams Water Refilling Station, these heavy metals, chemicals, and other contaminants can be removed depending on the type of purification system the water station you choose is using. Purifying water can also improve its quality and taste.
