Polluted groundwater discharge at a chlorinated solvent contaminated site in Hagfors, Sweden, is affecting a nearby stream flowing through a sparsely populated area. Because of difficulties related to source zone remediation, decision makers recently changed the short-term site management objective to mitigating discharge of polluted groundwater to...
A site in mid-western Sweden contaminated with chlorinated solvents originating from a previous dry cleaning facility, was investigated using conventional groundwater analysis combined with compound-specific isotope data of carbon, microbial DNA analysis, and geoelectrical tomography techniques. We show the value of this multidisciplinary approach,...
The preliminary state of my PhD project SPLASH.
A description of the conducted fieldwork at Blåisen, Norway and a description of the future fieldwork and laboratory work.
Soil contamination is a widespread problem and action needs to be taken in order to prevent damage to the groundwater and the life around the contaminated sites. In Sweden, it is estimated that more than 80,000 sites are potentially contaminated, and therefore, there is a demand for investigations and further treatment of the soil. In this paper, w...
Over 100,000,000 people worldwide are exposed to high arsenic groundwater utilised for drinking or cooking. The consequent global avoidable disease burden is estimated to be of the order of 100,000 avoidable deaths or more per annum from just direct exposures – i.e. excluding indirect exposure (from rice and other foods) and excluding morbidity. No...
Although many studies have been performed to investigate the spectral induced polarization (SIP) response of nonaqueous phase liquid (NAPL)-contaminated soil samples, there are still many uncertainties in the interpretation of the data. A key issue is that altered pore space geometries due to the presence of a NAPL phase will change the measured IP...
Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are found in aquatic systems, flora, and fauna worldwide. These potentially harmful compounds are also frequently detected in Sweden and have already resulted in severe problems for public drinking water supply, i.e., some wells had to be closed due to high PFAS concentrations both in raw water...
Characterization of varying bedrock properties is a common need in various contexts, ranging from large infrastructure pre-investigations to environmental protection. A direct current resistivity and time domain induced polarization (IP) survey aiming to characterize properties of a Cretaceous limestone was carried out in the Kristianstad basin, Sw...
Globally, an enormous number of polluted areas are in need of remediation to prevent adverse effects on health and environment. In situ remediation and especially the monitoring thereof needs further development to avoid costly and hazardous shipments associated with excavation. The monitoring of in situ remediation actions needs easier and cheaper...
Poly- and perfluoroalkyl substances (PFASs) are a group of anthropogenic environmental pollutants which have been used and produced for more than 60 years. PFASs are used for multiple industrial purposes, e.g. as water repellent on clothing, leather, and paper and as firefighting foam. The most well studied PFASs subgroup are perfluoroalkyl acids (...
Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are a group of anthropogenic environmental pollutants that are of almost ubiquitous occurrence and are found worldwide in the aquatic environment, wildlife and humans. They are among the ever growing group of emerging organic contaminants and have recently attracted huge attention (e.g. Simon 20...
In the Southern part of Hanoi, high ammonium (NH4+) concentrations in reducing groundwater have been an issue over the last 25 years. Elevated NH4+ concentrations in groundwater, in general, are an indicator of influences from anthropogenic sources, but the buried peat layers in the Red River delta formation are also hypothesized to contribute to t...
WHAT ARE PFASS? Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are a group of anthropogenic environmental pollutants that are found worldwide in the aquatic environment, wildlife and humans. PFASs have been produced since the 1950s and have multiple industrial uses, e.g. as water repellents in clothing, paper coatings or firefighting foam (P...
Twenty-five public supply wells throughout the hydrogeologically diverse region of Scania, southern Sweden are subjected to environmental tracer analysis (3H–3He, 4He, CFCs, SF6 and for one well only also 85Kr and 39Ar) to study well and aquifer vulnerability and evaluate possibilities of groundwater age distribution assessment. We find CFC and SF6...
Perfluoroalkyl substances (PFAS) are a group of anthropogenic environmental pollutants that are widely distributed in the global environment. They have multiple industrial uses, including water repellents in clothing, paper coatings and firefighting foam. According to a study released by the Environmental Directorate of the OECD, they are persisten...
Twenty-three south-Swedish public supply wells were studied to assess pesticide pollution of regional groundwater resources. Relations between pesticide occurrence, hydrogeology, and land use were analyzed using Kohonen's Self-Organizing Maps approach. Pesticides are demonstrated to be substantially present in regional groundwater, with detections...
Drilling with subsequent laboratory tests on soil and groundwater samples is the conventional method used to delineate contamination plumes in soils. Chlorinated hydrocarbons, which belong to a group of fluids referred to as DNAPLs (Dense Non-Aqueous Phase Liquids), implicates especially severe conditions since they are very toxic and only a small...
Using 3H and 3He data for calibration, a 2-D catchment-scale transport model was set up to explain the occurrence of bentazone, dichlorprop, glyphosate, isoproturon, MCPA and metamitron in a small groundwater catchment in southern Sweden. The model was parameterised with site-specific degradation and sorption data to enable transport simulations. L...
In this paper we present new relative sea-level data from southern Greenland, a key area for understanding the Greenland Ice Sheet (GIS) response to climate change. Within fourteen lakes and marine lagoons from the inner part of Bredefjord (Nordre Sermilik) in southern Greenland, isolations revealed by stratigraphic and palaeoecological analyses ar...
We have assessed the ability of a range of pesticide, site and climate parameters to discriminate between detected and non-detected pesticides as observed by long-term monitoring data of pesticide use and groundwater occurrence in a small catchment in southern Sweden. Of seventeen investigated parameters, six demonstrated such an ability: dosage ap...

Arsenic enrichment of groundwater in the Red River (Song Hong) delta in Vietnam was discovered in 1998. Several studies performed in this area found concentrations of As exceeding the WHO-guideline of 10 μg/L. This study focuses on an area south of Hanoi city, Nam Du, where a new well field came into operation in 2004. The new well field is situate...
Quaternary glacial stratigraphy and relative sea-level changes reveal at least two glacial expansions over the Chelyuskin Peninsula, bordering the Kara Sea at about 77°N in the Russian Arctic, as indicated from tills interbedded with marine sediments, exposed in stratigraphic superposition, and from raised-beach sequences mapped to altitudes of at...
Following the Holocene thermal maximum, the Greenland ice sheet began to expand, and many local glaciers formed. The maximum extent of most outlet glaciers from the Inland Ice was reached around 100 to 200 years ago. However, some exceptions have been recorded. In southern Greenland, the Neoglacial Narssarssuaq stade marks an older re-advance that...
We present results from an investigation of relative sea-level changes in the Qaqortoq area in south Greenland from c.11 000 cal. yr BP to the present. Isolation and transgression sequences from six lakes and two tidal basins have been identified using stratigraphical analyses, magnetic susceptibility, XRF and macrofossil analyses. Macrofossils and...
We present new results for relative sea-level change for southern Greenland for the interval from 9000 cal. yr BP to the present. Together with earlier work from the same region this yields a nearly complete record from the time of deglaciation to the present. Isolation and/or transgression sequences in one lake and five tidal basins have been iden...
New results are presented from the investigation of relative sea-level changes in the Nanortalik and Qaqortoq-Narsarsuaq areas in SW Greenland from c. 11 000 cal. years BP to the present Isolation and transgression sequences from seven lakes and seven tidal basins are identified using some of the traditional methods such as stratigraphic descriptio...
