Why is well water not considered as safe as tap water? 【Basic Knowledge】
What is the difference in safety between deep wells and shallow wells? The geological layers hold the key!
■What is the difference between well water and tap water? Tap water is treated with chemicals for sterilization, enhancing its safety, while well water is simply drawn from underground without undergoing disinfection processes. ■Is not all well water safe? Generally, well water used for drinking as "mineral water" is drawn from deep wells, which are considered to be about 30 meters or more below the surface. In contrast, water from shallow wells (within about 8 meters from the surface), commonly found in households, is not considered as safe compared to deep well water. ■Why is deep well water considered safe? Deep well water passes through multiple layers of soil before reaching the depths, providing thorough filtration. It is often sandwiched between clay layers, which can offer antibacterial effects, and it accumulates rich minerals during its journey through the soil layers. On the other hand, shallow wells are more susceptible to surface contamination due to their shallow depth, often rendering the water undrinkable.
