Emerging Contaminants in the Natural Environment
In Canada, 89% of drinking water is produced from surface water. Pesticides, pharmaceuticals, and industrial chemicals are typical contaminants that find their way to the environment where they can affect the health of humans and ecosystems. Some contaminants can be easily eliminated under the action of naturally occurring microorganisms, under aerobic or anaerobic conditions, while others undergo photodegradation, adsorption – desorption, or plant uptake. However, a portion of these contaminants resists these processes and might be transferred to the food web. My research group studies the transport, transfer, and transformation processes that govern their fate in the natural environment, including surface water and sediments, to help authorities adopt the most suitable control and remediation strategies.
Ecological Engineering Practices for Green Water Infrastructures
Reducing contaminant fluxes as close as possible to their sources with cost-effective water treatment solutions protects aquatic ecosystems and avoids large-scale downstream treatment. We work on developing Ecological Engineering Practices such as constructed wetlands to eliminate these contaminants. Because mixtures or “cocktails” of multiple contaminants are often present, each presenting a range of physical and chemical properties, Ecological Engineering Practices must be systematically designed to enhance their intrinsic water treatment capabilities.
Stable Isotope Analysis
Our lab develops new analytical methods to determine stable carbon and hydrogen isotopes of these priority organic contaminants, particularly using Compound Specific Isotope Analysis (CSIA). CSIA can help distinguish between permanent or “destructive” removal and temporary processes that simply redistribute contaminants in the environment. Information about contaminant isotope ratios can also help identify their sources or the reaction mechanisms affecting their persistence or removal in contaminated environments. We use CSIA to evaluate the role of natural attenuation processes in the field, and to evaluate the efficiency of Ecological Engineering Practices.
