If your water source is well or borehole, you need to read this!
Water is not only a resource; it is important to human life as air is. Despite this great importance, just 0.62% of the earth’s water is fresh and available for use. This minute percentage makes up the rivers, streams, lakes, ponds and groundwater.
Groundwater which is the major source of water of most homes through borehole or well are prone to contamination through seepage of contaminated surface runoff, since most of them are sunk at a shallow depth and poorly constructed. Groundwater contamination is rampant during rainy seasons as the surface runoff or flood as the case may be is majorly made up of wastewater.
Wastewater, water that has already been used for domestic, municipal, commercial or industrial applications can become a point source of pollution to your boreholes and wells if not properly managed and this could be detrimental to your health. You are likely to have diseases such as cholera, dysentery, typhoid, intestinal disorder, stomach ulcer and other degenerative heart diseases caused by bacteria, protozoa or viruses if you consume water contaminated with untreated wastewater. These ailments can be fatal and have been known to impair human production.
Furthermore, increased poor waste management practices in some areas of Ogun, Lagos and Rivers state have led to increased deposition of heavy metals to their soil. These heavy metals are stable and persistent environmental contaminants since they can neither be degraded nor destroyed. Therefore, they tend to accumulate in soils and sediments and later seep into your boreholes and wells during season of heavy rainfall. The common heavy metal contaminants include; Arsenic, Cadmium, Chromium, Lead, Mercury,Nickel, Zinc among others. When you consume water contaminated with these heavy metals, they lower your energy levels and damage the functioning of the brain, lungs, kidney, liver, blood composition and other important organs in the body while repeated long-term exposure could cause cancer or death.
Public water supply systems are not exempted from these hazardous contaminants that flow with flood. Most of the water pipelines run through drainages and water can be contaminated during periods of low pressure through slight opening on pipes.
In order to improve quality of water consumed and consequently to protect people and animals from the perils of water contamination, it is crucial to initiate measures to check the pollution from domestic and industrial effluents and to establish on-site regular water quality monitoring.
If these measures are not in place, it is advisable you consult an expert in water and sanitation to analyse your water.
