Fate And Transport Of Toxoplasma Gondii Oocysts In Saturated Porous Media: Effects Of Electrolytes And Natural Organic Matter, Christian Pullano
Fate And Transport Of Toxoplasma Gondii Oocysts In Saturated Porous Media: Effects Of Electrolytes And Natural Organic Matter, Christian Pullano
All Theses
Toxoplasma gondii is a pathogenic microorganism that is currently a threat to public health. Understanding the fate and transport of T. gondii through the soil and groundwater is vital in determining the risk it poses to water resources and human health. The physico-chemical interactions between the groundwater and the bio colloid within an aquifer will dictate its mobility and its ability to infect humans. This research examines how various naturally occurring groundwater chemistries containing organic compounds and monovalent and divalent salt solutions will alter the fate and transport of T. gondii. Solutions containing various concentrations of humic acid, fulvic …
Identification Of Patterns And Controls Of The Distribution Of Groundwater Discharge To Streams, Curtis Gebhard
Identification Of Patterns And Controls Of The Distribution Of Groundwater Discharge To Streams, Curtis Gebhard
All Theses
Groundwater discharge is a key component in understanding the interaction between groundwater and surface water. It provides baseflow to streams and can transport nutrients and contaminants to related aquatic ecosystems. It can also influence fish behaviour, spawning, migration and provide areas of refuge during summer and winter months. There are a variety of techniques that are used to characterize the magnitude of groundwater discharge including seepage meters, field permeameters, and piezometers and manometers, however the controls for the magnitude and distribution of discharge remain poorly understood. The purpose of this study was to conduct field investigations complimented with numerical analysis …
