Assessing Innovative Technologies for Nitrate Removal from Drinking Water
(University of Waterloo, 2010-01-22)Several health problems may be caused by excess nitrate in drinking water, the most important of which being methemoglobinemia, a potentially fatal disorder, in infants under six months of age. Many different parts of ... -
A Bench-scale Evaluation of the Removal of Selected Pharmaceuticals and Personal Care Products by UV and UV/H₂O₂ in Drinking Water Treatment
(University of Waterloo, 2006-12-22)A bench-scale study of the degradation of four selected pharmaceuticals and personal care products (PPCPs) was carried out using UV and UV/H₂O₂ treatment employing low pressure (LP) and medium pressure (MP) lamps. The ... -
Biofiltration-based “green technology” as a techno-ecological nature-based solution for drinking water treatment and climate change resilience
(University of Waterloo, 2022-06-02)While drinking water treatment process design is based on current and anticipated source water quality, changing climate makes it increasingly difficult to anticipate drinking water source quality and treatability. Although ... -
Contemporary Forest Harvesting Impacts on Drinking Water Quality and Treatability
(University of Waterloo, 2019-10-31)Forested watersheds supply ~75% of global accessible freshwater resources and serve as important sources of drinking water. Both natural and anthropogenic landscape disturbances in these regions can deteriorate water quality ... -
Conventional and Oxidant-amended Biofiltration to Improve Treatment Resilience in Drinking Water Systems Vulnerable to Wildfire
(University of Waterloo, 2024-01-26)Climate-change-exacerbated landscape disturbances can create obstacles for the provision of safe drinking water. The threats posed by wildfires are of particular concern due not only to the potentially extreme nature of ... -
The Effect of Selected Coagulants on Chloride-to-Sulfate Mass Ratio for Lead Control and on Organics Removal in Two Source Waters
(University of Waterloo, 2009-01-22)Lead is a known toxin, with the ability to accumulate in the human body from as early as fetal development. Lead exposure is known to cause a myriad of health effects which are more prominent among children. Health effects ... -
Evaluating expected microcystin removal at three Ontario drinking water treatment plants
(University of Waterloo, 2018-09-19)Cyanotoxins are a group of toxins produced by cyanobacteria that can be harmful to human health. Drinking water is a major pathway to exposure and therefore the presence of cyanobacteria and cyanotoxins in drinking water ... -
Evaluation of Potential Health Risks from Microplastics in Drinking Water
(University of Waterloo, 2021-05-03)Microplastics have been detected, often abundantly, in freshwater environments over the past decade. While understanding of the ecological health implications of microplastics in aquatic environments has advanced considerably, ... -
Examining drinking water security and governance for rural coastal Nova Scotia within the context of climate change
(University of Waterloo, 2015-05-21)Drinking water security, which most broadly refers to water of adequate quality and quantity, has largely been understudied within a Canadian context. This may coincide with the common misperceptions that Canada has an ... -
Identification and characterization of toxic cyanobacteria in two forested maritime watersheds in North America
(University of Waterloo, 2021-06-01)Healthy forested watersheds naturally provide high quality drinking water to communities. However, the integrity and quality of these water sources may be threatened by climate change-exacerbated disturbances such as ... -
Investigating Cyanobacterial Communities Across Canada and Characterizing the Seasonality of Cyanobacterial Toxin and Nitrogen Metabolism Genes in the Turkey Lakes Watershed Using Metagenomics
(University of Waterloo, 2023-08-08)The long evolutionary history of gram-negative cyanobacteria has enabled them to tolerate extreme conditions, succeed in numerous habitats, and exploit special nutrients, all while resisting harmful anthropogenic and climate ... -
Investigating the Role of Water Quality on the Galvanic Corrosion of Lead in Hard Drinking Water with a Focus on NOM
(University of Waterloo, 2020-05-25)Although the use of lead in water distribution systems is currently prohibited in Canada, old lead service lines, lead solder, and lead containing plumbing fixtures continue to be sources of lead in the tap water of many ... -
The Multiple Barrier Approach to Safe Drinking Water for First Nations Communities: A Case Study
(University of Waterloo, 2010-01-21)The drinking water contamination tragedy in Walkerton, Ontario during the spring of 2000 led to many changes in water management for the province. Among these changes has been the increased use of the multiple barrier ... -
Occurrence and Seasonal Variability of Selected Pharmaceuticals in Southern Ontario Drinking Water Supplies
(University of Waterloo, 2007-04-27)The presence and seasonal variability of human and veterinary pharmaceuticals in surface water (raw water) and treated water samples from two drinking water facilities in Southern Ontario was investigated. Water samples ... -
Treatment of the Cyanotoxin Anatoxin-a via Activated Carbon Adsorption
(University of Waterloo, 2015-05-22)Cyanobacteria are bloom-forming aquatic microorganisms that impact many drinking water sources and can produce a variety of toxins, eponymously termed cyanotoxins. Three cyanotoxins are of particular concern in a North ...
