Water Series (3): Arsenic Contamination in Drinking Water

Following our post about fluoride contamination last week, our water series is now focused on the equally serious problem of arsenic contamination. Some arsenic is present in all groundwater sources (see table 1). Of course this is only a problem if the arsenic has the chance to leak into groundwater as it filters through the rock. Arsenic leaching is more likely to occur in groundwater that is ho ...[Read More]

Friday Photo (56): Photos from Industry – Copper Deposits in Fault Zones

The deposits on the surface of this sandstone are a distinctive shade of green – indicative of copper. Copper is mobilised and concentrated along fault zones. If you have any photos from time spent working in industry, that do not breach company copyright regulations, then please get in touch and we will publish them on our blog!

Chilean volcanoes: shaken, but not always stirred?

November 7th marked the 175th anniversary of one of the largest earthquakes to have struck northern Patagonia. The earthquake, which is estimated to have had a magnitude of 8, had an epicentre close to Valdivia, and was accompanied by significant ground shaking and subsidence as far south as Chiloe island, and a major tsunami that reached Hawaii.  The eyewitness reports of the time have been well ...[Read More]

Hurricane Sandy: A round up of the coverage from Haiti to New York

We thought we would summarise the coverage of Hurricane Sandy and direct you to some of the wide-ranging political, scientific and development based discussion that has arisen in the last few weeks; simply follow the links in this article. Hurricanes are just one of the many natural disasters that affect countries in the Caribbean, such as Haiti. They are rarely an issue further north, but Sandy i ...[Read More]

Water Series (2): Fluoride Contamination in Drinking Water

This week, as part of our ‘water series’ we will focus on fluoride contamination in drinking water. In some parts of the UK we add fluoride to our drinking water, because small amounts can help to protect your teeth. However, too much fluoride (>1.5mg/L) can lead to a serious medical condition called fluorosis, affecting the development of teeth and bones. This strong dosage dependency can lead ...[Read More]

Friday Photo (55): Photos from Industry – Man Operating Machinery at a Mine in China

Man Operating Machinery at a Mine in Anhui Province, China There are many large mining operations covering Anhui Province, China. They tend to have limited safety regulations. The mines can ruin the landscape, cause pollution and can be dangerous places for people to work. However, this primary industry is fuelling China’s rapid growth and development. Our Friday Photo series will be focused ...[Read More]

Water Series (1): The Quantity and Quality of Groundwater

The water available in or near your home can vary dramatically over short distances. In Manchester, there is a robust supply of fresh water from the Lake District, whereas in London (only 200 miles away) the water has passed through limestone, leaving it with a cloudy taste and causing limescale build-up. Signs up on the London underground at the moment are encouraging people to save water by taki ...[Read More]

Friday Photo (54) – Debris Flow Channel, Gansu Province, China

Southern Gansu Province, China: Poorly Maintained Debris Flow Channel This channel is designed to transport debris flow material away from the road, thus preventing a major road blockage. The poor design and maintenance of the channel, however, is resulting in material coming down the channel and then being pushed back on to the road. (c) Geology for Global Development, 2012

Introducing the GfGD National Committee (1)

Geology for Global Development has now been operating for around 18 months. In such a short time, the Founder and Director, Joel Gill, has overseen vast amounts of growth. GfGD has expanded beyond its initial horizons and so we have established a national committee. These positions were advertised through the blog over the past few months and have been enthusiastically taken up by a team of dedica ...[Read More]
