Drought affects our water quality!
Hey everyone – as you know it’s National Water Week!
This is especially important in South Africa, which is naturally a very dry country. Access to fresh water is a constant issue in our communities and when water is scarce, we need to pay very close attention to water quality!
A long wait for water
Since 2014 South Africa has been struggling with a water shortage. This is thought to be primarily due to two main causes: global climate change, and the current El Niño event, which typically brings hotter, drier weather to southern Africa. Now, going into the 2016 calendar year, our country faces one of our worst droughts in over 23 years, according to some reports.
An area is said to be in a state of drought when it experiences less than 75% of its usual rainfall. This in itself is no disaster; it becomes a disaster when it impacts local people and the environment to a point where they can no longer manage without assistance. So far, five provinces in South Africa have been declared disaster areas. These are Mpumalanga, Limpopo, KwaZulu-Natal, North West and the Free State. Parts of the Eastern Cape, Western Cape and Northern Cape are heavily affected as well.
What does this mean for us?
The drought poses a serious threat to our communities. The lack of drinking water can lead to dehydration and even heat stroke when it gets very hot. These are very serious, especially in areas without good medical facilities.
With less water available, the quality of the water also gets worse. Because there is less water, the concentration of dissolved chemicals in the water increases. This makes fresh water even more scarce!
Another impact is that, with less water, people generally save the water that they have for drinking only. They don’t wash their hands as often as usual, and this can lead to water-washed diseases such as skin and eye infections, as well as diarrhoeal diseases. These are caused by harmful micro-organisms that are passed on by touching things and other people, due to a lack of clean water for washing.
