Sensitivity of ancient Lake Ohrid to local anthropogenic impacts and global warming

Alfred Johny Wüest

Human impacts on the few ancient lakes of the world must be assessed, as any change can lead to an irreversible loss of endemic communities. In such an assessment, the sensitivity of Lake Ohrid (Macedonia/Albania; surface area A = 358 km(2), volume V = 55 ...

Adsorption as a cause for iron isotope fractionation in reduced groundwater

Urs von Gunten

Iron isotopes were used to investigate iron transformation processes during an in situ field experiment for removal of dissolved Fe from reduced groundwater. This experiment provided a unique setting for exploring Fe isotope fractionation in a natural syst ...

Steepness expansion for free surface flows in coastal aquifers

David Andrew Barry

Free surface flow of groundwater in aquifers has been studied since the early 1960s. Previous investigations have been based on the Boussinesq equation, derived from the non- linear kinematic boundary condition. In fact, the Boussinesq equation is the zero ...

Investigation of the inhibitory effect of silica on the degradation of 1,1,1-trichloroethane by granular iron

Tamar Kohn

Although iron-based permeable reactive barriers are gaining importance for treating groundwater contaminants, little is currently known about the effect of cosolutes on barrier longevity. Because of their corrosion inhibiting properties, dissolved silica s ...

Typology of recent groundwaters from different aquifer environments based on geogenic tracer elements

A key problem in environmental science and in engineering geology is the often incomplete understanding of the origin of dissolved components in groundwater. The dissolved contents of trace elements in groundwater are of special importance for groundwater ...

Behavior of arsenic and other redox-sensitive elements in Crowley Lake, CA: A reservoir in the Los Angeles Aqueduct System

Janet Gordon Hering

Elevated arsenic concentrations in Crowley Lake derive from upstream geothermal inputs. We examined the water column of Crowley Lake under stratified and unstratified conditions, seeking evidence for algal uptake and transformation of arsenic and its depos ...

Effects of elevated CO2 and mineral nitrogen deposition on growth, allocation and decomposition of Sphagnum fallax, Polytrichum strictum and Eriophorum vaginatum in a Sphagnum bog.

Andy Siegenthaler

Atmospheric CO2-C sequestration is directly related to the formation of peat which in turn is dependent on the production and decomposition of plant material. We studied the various aspects of qualitative and quantitative growth, litter production and deco ...

Méthode de détection et de caractérisation de pollutions du sous-sol par les sites contaminés à l'aide des traces inorganiques

Contaminated sites form one of the major causes of environmental pollutions, in particular those of the soil and of the underground. One of the main problems presented by these sites is their location. Since water is the main contamination support in soil ...

Trichloroethene (TCE) contamination in an unconfined sand aquifer underlying a residential area of Perth, Western Australia

David Andrew Barry

Substantial TCE and ammonium contamination was detected in groundwater beneath a residential area in Perth, Western Australia. Investigation has successfully determined broad aspects of the extent of the TCE plume and its impact. The advective front of the ...
