Transport and Recovery of Bacteriophage PRD1 in a Sand and Gravel Aquifer: Effect of Sewage-Derived Organic Matter
Ann P. Pieper,Joseph N. Ryan,Ronald W. Harvey,Gary L. Amy,Tissa H. Illangasekare,David W. Metge +5 more
TL;DR: In this article, the effects of sewage-derived organic matter on virus attachment were tested in an aquifer on Cape Cod, MA, where 32P-labeled bacteriophage PRD1, linear alkylbenzene sulfonates (LAS), and tracers were injected into sewage-contaminated and uncontaminated zones of an iron oxide-coated quartz sand and gravel aquifer.
Journal ArticleDOI
Role of physical heterogeneity in the interpretation of small‐scale laboratory and field observations of bacteria, microbial‐sized microsphere, and bromide transport through aquifer sediments
TL;DR: The effect of physical variability upon the relative transport behavior of microbial-sized microspheres, indigenous bacteria, and bromide was examined in field and flow-through column studies for a layered, but relatively well sorted, sandy glaciofluvial aquifer as mentioned in this paper.
Journal ArticleDOI
Effects of the antimicrobial sulfamethoxazole on groundwater bacterial enrichment.
Jennifer C. Underwood,Ronald W. Harvey,David W. Metge,Deborah A. Repert,Laura K. Baumgartner,Richard L. Smith,Timberly M. Roane,Larry B. Barber +7 more
TL;DR: Results of these growth and nitrate reduction experiments collectively suggest that subtherapeutic concentrations of SMX altered the composition of the enriched nitrate-reducing microcosms and inhibited nitrates reduction capabilities.
Journal ArticleDOI
What Makes a Natural Clay Antibacterial
Lynda B. Williams,David W. Metge,Dennis D. Eberl,Ronald W. Harvey,Amanda G. Turner,Panjai Prapaipong,Amisha T. Poret-Peterson +6 more
TL;DR: Compared the depositional environments, mineralogies, and chemistries of clays that exhibit antibacterial effects on a broad spectrum of human pathogens including antibiotic resistant strains, it is deduced that extracellular processes do not cause cell death.
Journal ArticleDOI
Field and laboratory investigations of inactivation of viruses (PRD1 and MS2) attached to iron oxide-coated quartz sand.
Joseph N. Ryan,Ronald W. Harvey,David W. Metge,Menachem Elimelech,Theresa Navigato,Ann P. Pieper +5 more
TL;DR: Comparisons of estimated solution and surface inactivation rates indicates solution inactivation is approximately 3 times as fast as surface in activation, which may be substantially underestimated owing to slow release of inactivated viruses.
