The Toronto and Region Area of Concern (TRAOC) has been one of the most polluted sites in the Great Lakes posing health risks to millions of people. The Remedial Action Plan (RAP) has made significant progress towards restoring the system and meeting the delisting targets. Yet, several critical questions still need to be addressed, such as: How close is the Toronto ecosystem currently to meeting the TRAOC RAP delisting criteria? What additional research and assessment will be required to guide remedial actions? Which attributes best reflect the integrity and health of the ecosystem?
The lightning return-stroke is the vital component of a lightning flash since it causes most of the lightning-related damages/disturbances to electric power lines and installations. This research emphasizes the development of a lightning return-stroke model in order to analytically correlate the lightning current, usually measured at a tall structure, to its associated lightning electromagnetic pulse (LEMP).
Chinese cities are amongst the fasted growing cities in the world and they have per capita greenhouse gas (GHG) emission rates that are similar to western cities. This research quantifies GHG emissions for the three Chinese city]provinces of Beijing, Shanghai and Tianjin. A computer model is then developed for projecting the future growth in Shanghaifs emissions under current policies and infrastructure plans.
Domestic/municipal wastewaters in rural areas are often treated using septic tank systems which are often not very efficient. Because of this, effluent from septic systems often pollutes rivers, lakes and groundwater. To address this, Stantec, along with Ecowork of Japan, is interested in evaluating an innovative septic system for Essex, Ontario, where a pilot unit will be set up and run for 12 months. All important pollution parameters will be evaluated and the process and design parameters will be optimized.
The project will examine the environmental impact of using anaerobic digestion for the processing of the organic faction of municipal solid waste in the Partners in Project Green (PPG) Eco]Business Zone (EBZ). This project will be a partnership between a masterfs student at the University of Waterloo (UW), the Toronto and Region Conservation Authority (TRCA), the Greater Toronto Airports Authority, the Region of Peel, and Yield Energy (YE). The project will build upon the work already completed by Yield Energy in establishing a business case for anaerobic digestion.
The Nut Brook-Kelligrews River watershed is located at the western outskirts of the city of St. John's, Newfoundland. The area has been impacted due to industrial, agricultural, and commercial activities in the watershed and public concerns have been raised on the environmental impacts from these activities on the water quality of the rivers flowing through a residential community prior to discharging into Conception Bay.
The relationship of biodiversity to trail density (e.g. meters of trail per hectare) will be the focus of this internship, an attempt to determine the carrying capacity of ecosystems for trail density.
Urban forests, characterized by trees and green spaces in urban areas, are highly prized for their socioeconomic and environmental contributions to society. Models to quantify the benefits of urban forests exist (energy savings, storm water mitigation etc.), but there is no process by which the models' results are then directed towards the broader planning goals of a municipality.
Separation of dissolved solids (sodium sulfate salt) from effluent wastewater of TODA Inc. in Sarnia will be experimentally explored based on the proposed/recommended technology by the Company. In the first term of the internship, several technologies from the State-of-the-arts and Best Available technologies have been reviewed, analyzed and compared according to environmental and economical aspects. Newly innovated technology "Membrane Crystallization" process was selected an approved by TODA for experimental verification. In this technology a hydrophobic membrane is applied.
Electronic waste such as computers is an increasing problem as they quickly become obsolete. Currently, most electronic waste is either landfilled or (often illegally) sent to developing countries to be recycled, since it contains valuable metals such as copper and gold. Electronic waste should be viewed as a resource rather than a waste material since it contains levels of valuable metals often ten times higher than can be found in naturally occuring ore deposits. Based on current metal prices, each kilogram of the metallic electronic waste sample at Kemetco is worth US $25.
