Cape Town, the second most populous city in South Africa, is experiencing the worst drought in recorded history. 3 years of prolonged drought have put Cape Town in a dire situation, where the taps are expected to run dry in May 2018. With Cape Town now entering the dry season with their dams less than 30% full, water quality monitoring becomes more important than ever.

Why is Water Quality Monitoring important? 

In South Africa, all water use is regulated by the National Water Act of 1998. This act stipulates what water can be used for, where it can be used and in what quantities. It also advises on water waste products and how they are to be legally and efficiently disposed of. This obviously affects any business that uses water and with the current Climate conditions, water management becomes extremely important.
Any business needs to monitor the quality of the water coming in (especially with dams at an all-time low, water quality could drastically drop) and ensure that the water they are expelling is free of water pollution with could taint and reduce the already limited supply.

How does Gondwana implement Water Quality Monitoring? 

Gondwana uses two distinct monitoring methods:

Surface monitoring – Many sources of water in South Africa are known as ‘surface sources” (rivers, lakes, damns). These sources are particularly prone to pollution as agricultural drainage (from irrigation wash-off, fertilisers and pesticides), industries’ chemical substances, mining acids and salts and effluent return flow (including bacteriological contamination, nutrients and salts) all run into the surface water. Water quality is monitored to ensure it is safe for human consumption and/or for other use.

Groundwater monitoring – Unfortunately, groundwater can also be polluted and contaminated. Groundwater is typically polluted by rainfall soaking through the earth or to the groundwater source, carrying with it chemical and natural pollutants. Groundwater sampling is done to ensure that this resource is not contaminated by industrial and other operations.
