Water Microbiology
Water has curious and unusual properties, al1d plays an important role in living systems. The natural source of water is precipitation. As the water precipitates it picks up airborne microorganisms. When it comes in contact with the soil, other microorganisms get into it from the soil, sewage, organic wastes, dead plants and animals.
Therefore, water for human use must be made free from microorganisms by filtration and/or chemical treatment to avoid harm.
