Influence of organic carbon loading, sediment associated metal oxide content and sediment grain size distributions upon Cryptosporidium parvum removal during riverbank filtration operations, Sonoma County, CA
TLDR
Although the grain-surface metal oxides were found to have a high colloid-removal capacity, this study suggested that any major changes within the watershed that would result in long-term alterations in either the quantity and (or) the character of the river's DOC could alter the effectiveness of pathogen removal during RBF operations.About:

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 Adhesive Parameters for Chemically Heterogeneous Porous Media
TL;DR: The model results show that the PDFs of colloid adhesive parameters at the REA scale were sensitive to the size of the colloid and the heterogeneity, the charge and number of grid cells, and the ionic strength.
Journal ArticleDOI
Modeling colloid and microorganism transport and release with transients in solution ionic strength
TL;DR: A calibrated model provided a satisfactory description of the observed release behavior for a range of colloid types and sizes and a general theoretical foundation to develop predictions for the influence of solution chemistry on the transport, retention, and release of colloids.
Journal ArticleDOI
Inorganic Geochemistry and Redox Dynamics in Bank Filtration Settings
TL;DR: This review presents the four main geochemical processes relevant for inorganic geochemistry, with a focus on iron (Fe) and manganese (Mn), during bank filtration: reduction near the bank, oxidation near the production well, carbonate dissolution, and sorption to aquifer materials.
Journal ArticleDOI
Removal of polystyrene microplastic spheres by alum-based coagulation-flocculation-sedimentation (CFS) treatment of surface waters
TL;DR: In this paper, the removal of carboxylated polystyrene (PS) microspheres in a wide size range (3, 6, 25, 45, and 90μm) in two types of real surface waters (Grand River and Lake Erie water) that are sources for full-scale drinking water treatment plants was investigated.

Evaluation of specific ultraviolet absorbance as an indicator of the chemical composition and reactivity of dissolved organic carbon.
James L Weishaar,George R. Aiken,Brian A. Bergamaschi,Miranda S. Fram,Roger Fujii,Kenneth Mopper +5 more
TL;DR: Data indicate that SUVA, determined at 254 nm, is strongly correlated with percent aromaticity as determined by 13C NMR for 13 organic matter isolates obtained from a variety of aquatic environments and is shown to be a useful parameter for estimating the dissolved aromatic carbon content in aquatic systems.
Book
Manual of environmental microbiology.
TL;DR: This book discusses water Microbiology in Public Health, soil, Rhizosphere and Phyllosphere, and the role of aerobiology in these environments.
Journal ArticleDOI
Modeling colloid attachment, straining, and exclusion in saturated porous media.
TL;DR: Numerical experiments indicated that increasing the colloid excluded volume of the pore space resulted in earlier breakthrough and higher peak effluent concentrations as a result of higher pore water velocities and lower residence times, respectively.
Journal ArticleDOI
Physical factors affecting the transport and fate of colloids in saturated porous media
TL;DR: In this article, the influence of colloid size and soil grain size distribution characteristics on the transport and fate of the colloid particles in saturated porous media was explored, and the final spatial distribution of retained colloids by the porous media were found to be highly dependent on the colloids size and the soilgrain size distribution.
Journal ArticleDOI
Biological activity and environmental impact of anionic surfactants
TL;DR: The role of anionic surfactants in the environment is ambiguous: they can cause serous environmental pollution with toxic effect on living organisms; otherwise, they can promote the decomposition and/or removal of other inorganic and organic pollutants from the environment.
