Water Quality Modeling in Kranji Catchment
… most important of these values is the bacterial die-off rate. This rate must be accurate for the model to provide accurate predictions of bacterial loadings. In order to obtain a value for the bacterial die-off rate, an attenuation study was conducted. The results of this study were not typical. …

Estimating Bacterial Loadings to Surface Waters from Agricultural Watersheds
… models are needed that describe bacterial die-off and transport processes under field conditions. Before these bacterial models can be developed, more field-derived information is needed regarding bacterial survival and transport. The objectives of this research were to evaluate bacterial …

Fate of Salmonella and Listeria monocytogenes in different frozen produce commodities
… CFU/g and stored at -18±2°C. Salmonella was enumerated at 0, 0.02, 1, 3, 6, 10, 15, 30, 60 and 90 days post inoculation (dpi), after storage at -18±2°C. Listeria monocytogenes monitoring followed the same structure, with an additional timepoint at 180 dpi. For objective 2, ten-gram samples of …

Fate and Transport of Pathogen Indicators from Pasturelands
… and then applying this method to analyze runoff samples collected from small box plots and large transport plots. The box plot experiments examined the partitioning of pathogen indicators in runoff from three different soil types while the transport plot experiments examined partitioning at …

Effect of Anaerobic Soil Disinfestation on Salmonella Concentration Using Different Soil Amendments
… The study aimed to compare Salmonella die-off following inoculation in ASD and non-ASD processed soil and compare Salmonella die-off in amended and non-amended soils following ASD. Two independent experiments were arranged in randomized complete block designs (four replications per …

A Combined Field And Laboratory Investigation Into The Transport Of Fecal Indicator Microorganisms Through A Shallow Drinking Water Aquifer In Bangladesh
… attachment modes incorporating bacterial die-off was developed. Where the two-population phenomenon was observed, one population typically was highly irreversible while the other was reversible with a smaller irreversible attachment rate. When applied to transport in the field, this model …
