Nuclear magnetic resonance methods for environmental diagnostics

2018/19-2019/20 • $169,235
The objective of the proposed research is to develop advanced analytical methods based on Nuclear Magnetic Resonance (NMR) to improve the characterization of complex environmental mixtures, including: (i) the development of novel analytical methods to rapidly identify and quantify the organic...

Field Testing of Novel Technologies for Restoring Challenging Contaminated Sites

2019/20 • $151,600
Cleaning up contaminated sites in Canada is a significant challenge, in part due to the limited cost effective technologies that can efficiently reduce contamination to safe levels. This is a particular challenge when impermeable soils, such as clay and silts, are contaminated. The use of...

Integrating microbial characterization tools into conceptual site models (CSMs) at complex contaminated sites

2018/19 • $275,635
This project is a very close collaboration between hydrogeologists and geochemists at Geosyntec Consultants (Guelph, ON) and technical experts at DuPont on an extensive team effort to better approach the multifaceted remediation of a large complex contaminated site. Remediation of such sites is...

Field Testing of Novel Technologies for Restoring Challenging Contaminated Sites**

2018/19 • $80,904
Cleaning up contaminated sites in Canada is a significant challenge, in part due to the limited cost effective technologies that can efficiently reduce contamination to safe levels. This is a particular challenge when impermeable soils, such as clay and silts, are contaminated. The use of...

NSERC Industrial Research Chair in Groundwater Contamination in Fractured Media

2012/13-2017/18 • $3,475,000
This proposal requests the renewal (second term: 2012-2017) of a Senior NSERC Industrial Research Chair in Groundwater Contamination in Fractured Media for Dr. Beth Parker, School of Engineering, University of Guelph. The IRC research program aims to i) develop a better understanding of the...

Evaluation and optimization of in situ chemical oxidation for groundwater remediation

2012/13-2015/16 • $930,652
Groundwater is an immensely important and conditionally renewable natural resource that is used as a supply for domestic and agricultural consumption and sustains a physical and chemical balance with the surface water system. Contamination caused by a wide spectrum of hazardous organic compounds...

NSC - Design and screening of DNA-functionalized hydrogels for contaminants in water

2013/14-2015/16 • $553,600
With the rapid increase in global population and continuous release of new chemical contaminants into the environment, maintaining safe and sufficient natural resources, especially water, has become increasingly challenging. It is strategically important to develop new technologies that target...

Exploring the use of EK-TAP technology for in situ remediation of groundwater and soil contaminated with oil-field produced wastewater

2015/16 • $25,000
Hydraulic fracturing and oil sands extraction are being increasingly used as means of recovering unconventional fossil fuel sources in Canada and around the world. The extraction technologies utilize large volumes of freshwater, and generate wastewater, known as oil-field produced wastewater....

Application of carbon dioxide and formaldehyde as tracers for optimizing sub-slab venting system design

2014/15 • $25,000
Sub-slab venting (SSV) and sub-slab depressurization (SSD) are common practices to control intrusion of volatile organiccompounds (VOC) and radon from subsurface to indoor air to protect the occupants from exposure to these harmful gases. These techniques are based on technology that is about 30...

Electrokinetics - A novel approach to assess contaminant mobility in soils

2014/15 • $25,000
Soil and groundwater contamination resulting from agricultural and industrial activities is a growing, worldwide problem, with far-reaching ecological, economic and health implications. Site assessment and clean-up are most challenging when dealing with fine-grained soils and aquifers containing...

Hg bioaccessibility assay for sorbent-amended sediments

2014/15 • $23,300
Mitigation of risk to ecological receptors from contaminants in sediments could be accomplished by sedimentdredging and disposal. Alternately, in situ treatment with a long-lasting sorbent to reduce bioavailability of thecontaminant is less costly and less ecologically disruptive. For sediments...

Assessment of nZVI synthesis and mobility at a field trial

2011/12-2013/14 • $115,869
The use of nanoscale zero valent iron (nZVI) for remediation of contaminated sites has received significant attention in part due to the ability of nZVI to rapidly transform contaminants in controlled laboratory experiments. One problem that has hampered the widespread implementation of nZVI is...

In situ STAR (Self-sustaining treatment for active remediation)

2011/12 • $114,200
Without industry, Canadians would not enjoy the prosperity they do. But the cost of this progress has been high: as many as 30,000 chemically contaminated sites around the country, each one a potential threat to human and environmental health. Whether because of poor disposal methods or...

Investigation of CSIA as an innovative quantitative tool for performance assessment of groundwater remediation at contaminated sites

2010/11 • $138,500
Contamination of groundwater by organic contaminants represents one of the most urgent challenges facing environmental scientists, industry, government regulators and society. This application addresses directly the Target Area Healthy Environment and Ecosystems, specifically addressing the...
