Journal ArticleDOI
Transport and straining of E. coli O157:H7 in saturated porous media
TL;DR: In this paper, the authors studied the transport and deposition behavior of pathogenic Escherichia coli O157:H7 under unfavorable electrostatic conditions in saturated quartz sands of various sizes (710, 360, 240, and 150 μm) and at several flow rates.
Journal ArticleDOI
Transport and Fate of Microbial Pathogens in Agricultural Settings
Scott A. Bradford,Verónica L. Morales,Wei Zhang,Ronald W. Harvey,Aaron I. Packman,Arvind Mohanram,Claire Welty +6 more
TL;DR: In this article, a number of transport pathways, processes, factors, and mathematical models often are needed to describe pathogen fate in agricultural settings, and the level of complexity is dramatically enhanced by soil heterogeneity, as well as by temporal variability in temperature, water inputs, and pathogen sources.
Journal ArticleDOI
Colloid transport in unsaturated porous media: The role of water content and ionic strength on particle straining
TL;DR: Experimental and modeling results suggest that straining--the retention of colloids in low velocity regions of porous media such as grain junctions--was the primary mechanism of colloid retention under both saturated and unsaturated conditions.
Journal ArticleDOI
Sensitivity of the transport and retention of stabilized silver nanoparticles to physicochemical factors
TL;DR: The results imply that AgNPs were largely irreversibly interacting in a primary minimum associated with microscopic heterogeneity.
Journal ArticleDOI
Straining, Attachment, and Detachment of Cryptosporidium Oocysts in Saturated Porous Media
Scott A. Bradford,Mehdi Bettahar +1 more
TL;DR: Experimental and modeling studies were undertaken to examine the roles of attachment, detachment, and straining on oocyst transport and retention, and a more physically realistic description of the data was obtained by modeling attachment, detachments, andstraining.
