Usually, it is safe to drink but sometimes it is found contaminated. The reason for its contamination can be, if there is a company near the well that poured chemicals in the ground or a farmer puts pesticides on their crops, the well water is likely to change and become a source of different diseases (Trottier, 2004).

From this 84% people, 80% population is concentrated in the Sub Saharan Africa, Eastern Asia and South Asia. The statistics further provide that out of 80% population, 50% people in Eastern Asia and 30% people in Sub-Saharan Africa cannot avail water from hygienic sources.
