Groundwater News Roundup (Jul/Aug 2017)

Too busy to keep up to date with groundwater news? Here's a quick roundup.

THIS WEEK’S DAM LEVELS

The City of Cape Town and the national Department of Water and Sanitation measures dam levels to check how much water is available for the region and whether water restrictions are necessary for residents and businesses.

HOW SEVERE IS THE DROUGHT?

For the past couple of weeks, we’ve all been watching the rain fall and its annual total rise, hoping for some reprieve from running around bathrooms with buckets, and frantic purchases of ridiculously overpriced rainwater tanks. It hasn’t happened. Rainfall has been meagre.

INITIATIVE AIMS TO USE NANOTECHNOLOGY TO PURIFY WATER

A five-year project focusing on the use of nanotechnology for addressing environmental challenges in Africa such as water contamination has received funding.

The project, which also aims to develop news systems capable of reducing the current cost of water purification methods, will be implemented through a collaboration involving Rhodes University, South Africa; University of Ottawa, Canada and United States International University -Africa (USIU-Africa) in Kenya.

SOUTH AFRICA'S FRESH WATER CHALLENGE

Water scarcity is a global challenge, with southern Africa being the hardest hit. South Africa is especially water stressed – ranked the 30th driest country in the world.

With annual rainfall levels about half the world average, South Africa also experiences unevenly distributed rainfall in our landscapes and we have a highly variable climate where droughts and floods are common.

NEW APP SHOWS AQUIFER LEVEL CHANGE AND SUBSIDENCE IN RELATION TO GROUNDWATER WITHDRAWALS IN HOUSTON-GALVESTON AREA

A new interactive web application illustrates how groundwater, sediment compaction and land-elevation change are related in the Houston-Galveston region in Texas. The new app was developed by the U.S. Geological Survey and is available online.

SPATIAL ANALYSIS OF FLUORIDE CONCENTRATIONS IN DRINKING WATER AND POPULATION AT RISK IN NAMIBIA

Namibia, the driest country in sub-Saharan Africa, is largely reliant on groundwater for its potable water demand and groundwater is a major source of naturally-occurring fluoride. This study assessed the spatial distribution of fluoride in potable water and appraised the population at risk for high fluoride intake.
