Windhoek’s boreholes dissected

03 February 2020 | Disasters

The threats of climate change and the current drought have prompted the dependency on production boreholes as a sustainable supply for domestic water in Windhoek.
Therefore, maintaining the production boreholes water quality is a vital intervention for a city like Windhoek. If you’re interested in knowing what the findings were of a study carried out on the capital’s production boreholes and water quality evaluation, don’t miss a talk by David Silas on this topic at the Scientific Society on Thursday (6 February).
The aim of David’s research is to provide an overview for evaluation of water quality for production boreholes in Windhoek, through applying geographic information system and geostatistical algorithms. The production boreholes water quality parameters (chloride, iron, temperature, pH and electrical conductivity) were sampled and analysed from existing production boreholes owned by the City of Windhoek.
The results showed that pro-active measures must be taken into consideration before the water from production boreholes is used for domestic purpose. The study also discovered that water from some production boreholes in certain areas of Windhoek is not safe for consumption due to high temperature causing bacteriological contamination.

He is a member of Youth Earth Scientist (YES) Network and the Society of Petroleum Engineers (SPE).
