1. Isotope Ratio and Trace Element Measurements Using Inductively Coupled Plasma – Mass Spectrometry : Method Development and Applications in Environmental Forensics
Abstract : Environmental Forensics is a scientific methodology developed for identifying sources, the timing of release, and transport pathways for potentially hazardous environmental contaminants. It combines a variety of analytical methods with principles derived from disciplines such as chemistry, geology, geochemistry, hydrogeology, and statistics, with the purpose to provide objective scientific and legal conclusions on the source and/or time of a contaminant release.

2. Stable and radiogenic isotopes as tracers for geochemical processes in mineralogically-complex mine waste environments : Insights from 13C, 2H, 18O, 34S and 87Sr/86Sr
Abstract : Mining and its related activities generate large volumes of mine wastes such as tailings that can have negative environmental implications. One of such mine wastes of potential environmental concern is the historical Yxsjöberg Cu-W-F skarn tailings in Sweden, which encompasses a complex mineralogy including sulphides, carbonates, silicates, oxides / wolframite and halides.

3. From precipitation to stream : isotopic insights into hydrological flow paths and transit times in boreal catchments
Abstract : Understanding the journey water makes from precipitation entering a catchment, traveling through soils, and the time it takes before it exits as stream water are questions of great relevance for both scientists and environmental managers. Natural stable isotopes such as δ¹⁸O and δ²H have been extensively used over the last decades to trace water through diverse catchments across the world. READ MORE

4. The importance of tree cover for water resources in semiarid West Africa
Abstract : The current paradigm in forest hydrology implies that an increase in tree cover always leads to reduced water yields as a result of increased interception and transpiration (ET) losses. This trade-off theory, in which more trees mean less water, has led to concerns that the establishment of trees in drylands may jeopardize scarce water resources. READ MORE

5. Hydrogeological modeling to improve remediation strategies for a drinking water aquifer contaminated by an aqueous phase liquid
Abstract : In many communities, groundwater is an important source of drinking water. Groundwater aquifers are, however, vulnerable to the widespread and increasing problem of contamination from anthropogenic sources. Once in the groundwater, contaminants are likely to remain there for a long time as the attenuation rate is slow. READ MORE
