Water borehole sinking in Africa – could this have a latter devastating effect?

The scarcity of pipe borne water has led to the sinking of boreholes in many developing countries, especially in Africa. This is due to the government negligence in providing clean water. To be more specific, water boreholes are very common in Nigeria. This is the only source of water the majority of the populace rely on. The borehole water do not undergo any sought of purification by chlorination or filtration, rather, they are pump directly for domestic use.

However, most private individuals installing the boreholes system also install a purification system. But this is not common, except for those packaging water for commercial purposes. Apart from private individuals who are involved in the sinking of boreholes, the government is also resorting to this as replacement for pipe borne water.

Before water boreholes became popular in Nigeria there use to be pipe born water for supply. At that time, there were a lot of water reservoir but was not efficient enough to meet the domestic demand for water. Instead of the government to increase efficiency and boast supply of clean water, they gave way to the sinking of boreholes. Also the government also carried out several projects on the sinking of boreholes without installing purification system.

Although the water from a very deep borehole may look clean and even when subjected to microbes examination, but this is not always the case. This is while for safety reasons most homes have some sought of mini purification system that they use in purifying the water they drink and use for cooking. But majority don’t have this system of purification.
Also, boreholes are exposed to underground pathogens and pollutants especially that is responsible for stomach upset that comes with diarrhea and massive lose of fluids. In the undergrounds the water might also be exposed to the natural radioactivity and natural occurring hazardous metals. Many of these heavy metals are toxic and carcinogenic. Therefore it is highly recommended that water from the boreholes is sampled for laboratory analysis and bio-chemical analysis before consumption.

In addition to the hazards caused by water from boreholes, the resulting drilling and digging of the ground soil for water may weaken the soil surface which can make the soil become porous. As a result of this vulnerability and lesser cohesion, erosion might be triggered. This is already happening in some part of the Nigeria.
