Viral Fate and Transport Modeling under Salinity Impact
This research studied the impact of salinity on sorption and transport of MS-2 in saturated sand through one-dimensional column experiments. MS-2 was used as a surrogate to understand...

Dengue Fever: Potential Threat to the Southern States

Year 2000: Are You Ready?
The year 2000 computer virus poses many potential problems for engineers. Programming designed decades ago may not recognize the date 01/01/00 as January 1, 2000. Hardware, software and...

Simulation of Unsaturated Zone Virus Transport Adjacent to Municipal Wells
The EPA proposed groundwater disinfection rule for municipal wells would allow exemptions if, among other options, the necessary virus source setback distance could be maintained to provide...

Patheogen Removal Beneath An Artificial Recharge Basin

Predicting Microbial Contamination of Ground Water
As a result of the drinking water standards for viruses established by the United States Environmental Protection Agency in 1985, mandatory groundwater disinfection requirements were recently...

Particle Size and Filter Performance: Model Studies

The Ozone Defense
Ozone is a molecule containing three oxygen atoms. When bubbled through drinking water, the third atom in ozone is attracted away by other molecules, a process called oxidation. This process...

Is It Safe to Eat the Seafood?
The issue of bacterial, viral and chemical contamination of Puget Sound seafood and its consequent impact on human health has been of concern for some time. This paper discusses potential...

Pilot Testing to Evaluate Virus Removal and Deactivation

The Incidence, Monitoring, and Treatment of Viruses in Water Supply Systems
A State-of-the Art Review
Two areas of growing concern in water treatment and public health are the potential for spread of viruses by water routes and the adequacy of current treatment and disinfection practices...

Chlorine Inactivation of a DNA-Containing Enteric Virus

Removal of Virus from Public Water Supplies

Virus Removal in Primary Settling of Raw Sewage
Previously published data indicate only minor removal of viruses during primary sedimentation of raw sewage. A reassessment based on quantitative estimates of viruses in temporally matched...

Kinetics of Enteroviral Inactivation by Ozone
An analysis of enteroviral inactivation by ozone was performed using kinetic expressions developed from mass balance information obtained from a continuous flow reactor. The rate of viral...

Ozone Inactivation of Floc Associated Viruses and Bacteria
It has been shown that some viruses and bacteria in their natural environment may exist embedded or adsorbed within various solid materials. These viruses may exhibit a totally different...

Virus Concentration by Ultrafiltration
A capillary membrane ultrafiltration unit was used for the concentration of poliovirus I from a volume of 100-l tap water. Backwashing the unit with either high pH glycine buffer or beef...

Transport of Viruses through Organic Soils and Sediments
A black organic sediment (l5.5% organic carbon) retained only 60% and 75% of virus suspended in secondary effluent and ground water, respectively. When some of the water-soluble humic...

Second-Decade Situation in Analysis of Artificial Heart Valves

Cost-Effective Use of Municipal Wastewater Treatment Ponds
Treatment ponds are a cost-effective alternative for municipal wastewater treatment. When compared to other secondary treatment alternatives, ponds are generally the least costly, require...
