High fluoride drinking water in Gokwe, northwest Zimbabwe
More than 200 million people worldwide are exposed to excessive fluoride in drinking water. According to the World Health Organization, the optimal concentration range of fluoride in drinking water is 0.5 to 1.5 mg/L. Above this range, populations may contract dental fluorosis or, in severe cases, crippling skeletal fluorosis. In the Gokwe area in NW Zimbabwe, where drinking water contains up ...

Karst groundwater: a challenge for new resources
Karst aquifers have complex and original characteristics which make them very different from other aquifers: high heterogeneity created and organised by groundwater flow, large voids, high flow velocities up to several hundreds of m/h, high flow rate springs up to some tens of m3/s. Different conceptual models, known from the literature, attempt to take into account all these particularities. The ...

Soils Characteristics of The Bassendean and Spearwood Sands of the Gnangara Mound (Western Australia) and their Controls On Recharge, Water Level Patterns and Solutes of The Superficial Aquifer
The flow pathways of water in the soils of the Gnangara Mound are highly irregular and depend upon the moisture content, the repellency and preferential wettability potential of the soils. The occurrence of preferential flow is more evident in dry soils. As the soil wets during the rainy season, the water repellence and differential wettability decreases, the fingering and the preferential flow ...

What are the differences between ASHP and GSHP
Air source heat pumps and ground source heat pumps work along very similar lines. There are, however, some minor differences between them which can have fairly significant implications. With that in mind, here is a quick guide to the key differences between air source heat pumps and ground source heat pumps. Understanding the technology The key difference between air source heat pumps and ...

Assessing the transport and fate of MTBE
Untitled Document Abstract The ether oxygenates MTBE and TAME have been used in petroleum fuel formulations in the UK since the mid-1980s and have led to contamination of major aquifers with these chemicals, including the Chalk aquifer of southern England. An assessment is made of the controls on the fate of MTBE and BTEX compounds at a contaminated site on the Chalk aquifer, ...
