Journal ArticleDOI
Fracture Aperture Measurements and Migration of Solutes, Viruses, and Immiscible Creosote in a Column of Clay‐Rich Till
Klaus Hinsby,Larry D. McKay,Peter R. Jørgensen,Melissa Lenczewski,Charles P. Gerba,Charles P. Gerba +5 more
TL;DR: In this paper, a series of ground-water flow and tracer experiments were performed on an undisturbed column of fractured clay-rich till, 0.5 m diameter by 0. 5 m long, in a pressure-controlled cell.
Journal ArticleDOI
Evaluation of chloride and pesticide transport in a fractured clayey till using large undisturbed columns and numerical modeling
TL;DR: The results of the tracer experiments are consistent with a conceptual model of advective transport along the fractures combined with diffusion into the fine-grained matrix between the fractures.
Journal ArticleDOI
Preferential flow and pesticide transport in a clay-rich till: Field, laboratory, and modeling analysis
Peter R. Jørgensen,Peter R. Jørgensen,Martin Hoffmann,Jens P. Kistrup,Claus Bryde,Rossana Bossi,Karen G. Villholth +6 more
TL;DR: In this paper, the authors investigated vertical flow and pesticide transport along fractures in water saturated unoxidized clayey till and showed that root growth along the fracture surfaces was the principal agent of fracture aperture enhancement.
Journal ArticleDOI
Transport and reduction of nitrate in clayey till underneath forest and arable land.
Peter R. Jørgensen,Johanne Urup,Tina Helstrup,Marina Bergen Jensen,Finn Eiland,Finn Pilgaard Vinther +5 more
TL;DR: Simulations using a calibrated discrete fracture matrix diffusion (DFMD) model could reasonably reproduce the denitrification and resulting flux of nitrate observed during variable flow rate from the columns.
Journal ArticleDOI
Migration of nutrients, pesticides and heavy metals in fractured
Peter R. Jørgensen,J. Fredericia +1 more
TL;DR: In this paper, a study of fractured clayey till shows that the hydraulic activity of groundwater flow and the migration of pollutants from an orchard and from arable land are by far the most intensive in the upper 10 m of the till.
