Geological realism in hydrogeological and geophysical inverse modeling : A review

Linde, Niklas ; Renard, Philippe ; Mukerji, Tapan ; Caers, Jef

In: Advances in Water Resources, 2015, vol. 86, p. 86-101

Scientific curiosity,exploration of georesources and environmental concerns are pushing the geoscientific research community toward subsurface investigations of ever-increasing complexity.This review explores various approaches to formulate and solve inverse problems in ways that effectively integrate geological concepts with geophysical and hydrogeological data. Modern geostatistical simulation...

Quantification of Degradation of Chlorinated Hydrocarbons in Saturated Low Permeability Sediments Using Compound-Specific Isotope Analysis

Wanner, Philipp ; Parker, Beth L ; Chapman, Steven W ; Aravena, Ramon ; Hunkeler, Daniel

In: Environmental Science & Technology, 2016, vol. 50, no. 11, p. 5622-5630

This field and modeling study aims to reveal if degradation of chlorinated hydrocarbons in low permeability sediments can be quantified using compound-specific isotope analysis (CSIA). For that purpose, the well-characterized Borden research site was selected, where an aquifer−aquitard system was artificially contaminated by a three component chlorinated solvent mixture (tetrachloroethene (PCE)...

Approaching Latin American Cities from the Bottom-Up: Self-Help Networks, Place Identity and Participatory Research

Riaño Alcala, Yvonne

In: Perspectives of Geographical Research on Latin America for the 21st Century. ISR-Forschungsberichte, 2000, vol. 23, p. 71-93

The quality of life in Latin American cities is increasingly deteriorating. Problems of environmental degradation, poverty, violence and criminality are heightening across the continent. One of the important reasons for this phenomenon is the inability of many urban residents to identify themselves with their environment. This is a result of equity problems, such as the deficient integration of...

Monitoring Biodegradation of Methyl tert-Butyl Ether (MTBE) Using Compound-Specific Carbon Isotope Analysis

Hunkeler, Daniel ; Butler, B.J ; Aravena, R ; Barker, J.F

In: Environmental Science & Technology, 2001, vol. 35, no. 4, p. 676-681

Methyl tert-butyl ether (MTBE), the most common gasoline oxygenate, is frequently detected in surface water and groundwater. The aim of this study was to evaluate the potential of compound-specific isotope analysis to assess in situ biodegradation of MTBE in groundwater. For that purpose, the effect of relevant physical and biological processes on carbon isotope ratios of MTBE was...
