Layering in shales controls microfracturing at the onset of primary migration in source rocks
(Peer reviewed; Journal article, 2020)The process of primary migration, which controls the transfer of hydrocarbons from source to reservoir rocks, necessitates the existence of fluid pathways in low permeability sedimentary formations. Primary migration starts ... -
Leachate emissions of short- and long-chain perand polyfluoralkyl substances (PFASs) from various Norwegian landfills
(Peer reviewed; Journal article, 2019)Restrictions on the use of long-chain per- and polyfluoralkyl substances (PFASs) has led to substitutions with short-chain PFASs. This study investigated the presence of four short-chain PFASs and twenty-four long-chain ... -
Leaching and transport of PFAS from aqueous film-forming foam (AFFF) in the unsaturated soil at a firefighting training facility under cold climatic conditions
(Peer reviewed; Journal article, 2019)The contaminant situation at a Norwegian firefighting training facility (FTF) was investigated 15 years after the use of perfluorooctanesulfonic acid (PFOS) based aqueous film forming foams (AFFF) products had ceased. ... -
Leaching potential of per- and polyfluoroalkyl substances from source zones with historic contamination of aqueous film forming foam - a surfactant mixture problem

Limited mobility of dioxins near San Jacinto super fund site (waste pit) in the Houston Ship Channel, Texas due to strong sediment sorption
(Peer reviewed; Journal article, 2018)Sediments from a waste pit in Houston Ship Channel (HSC) were characterized using a number of molecular markers of natural organic matter fractions (e.g., pyrogenic carbon residues, PAHs, lignins), in addition to dioxins, ... -
A literature review of risk matrices applied for risk assessment in geotechnical engineering
(NGI-rapport;20170774-D5.1, Research report, 2018-10-25)Risk matrices are frequently used for risk assessment in all kinds of areas. This study makes a simple literature review on their applications in different fields of geotechnical engineering with focus on their size and ... -
