Journal ArticleDOI
Ms-2 and poliovirus transport in porous media : hydrophobic effects and chemical perturbations
TL;DR: Results show that viruses experience reversible attachment/detachment, that large chemical perturbations are needed to induce rapid virus detachment, and that viruses should be quite mobile in sandy porous media.
Journal ArticleDOI
Efficacy of copper and silver ions and reduced levels of free chlorine in inactivation of Legionella pneumophila.
TL;DR: All disinfection systems, regardless of temperature or free chlorine concentration, showed increase inactivation rates when 400 and 40 micrograms of copper and silver per liter was added; however, this trend was significant only at 0.4 mg of free chlorine per liter.
Journal ArticleDOI
Virus and Bacteria Transport in a Sandy Aquifer, Cape Cod, MA
Roger C. Bales,Shimin Li,Kimberly M. Maguire,Moyasar T. Yahya,Charles P. Gerba,Ronald W. Harvey +5 more
TL;DR: In this paper, the authors studied the transport of the bacteriophage PRD-1, bacteria, and latex microspheres in a sandy aquifer under natural-gradient conditions.
Journal ArticleDOI
Virus transport and removal in wastewater during aquifer recharge
TL;DR: In this article, two 13 m2 basins were constructed in coarse sand alluvium, one for secondary-and one for tertiary-treated effluent, and a chemical tracer, potassium bromide (KBr), was added to effluent applied to these basins.
Journal ArticleDOI
A field example of bacteriophage as tracers of fracture flow
TL;DR: Two bacteriophages, MS-2 and PRD-1, were added to water to an initial concentration of 10 5 -10 6 pfu mL -1 in a trench-to-trench lateral groundwater flow and tracer migration experiment in the upper 55 m of a weathered and fractured clay-rich till Phage were detected in water from seepage collectors set in the wall of a downgradient (gradient=024) trench, located 4 m from the source trench, between 1 and 2 days after the start of the injection.
