A remote sensing-based wetland inventory and classification framework for Newfoundland and Labrador using satellite optical and synthetic aperture radar data

This project aims to develop a remote sensing based framework for Newfoundland and Labrador (NL) wetland inventory and classification and monitoring through the synergistic use of satellite and airborne multi-spectral and ortho-imagery and space-born synthetic aperture radar (SAR) data. The proposed project involves collaboration from C-CORE, Ducks Unlimited Canada, and Santec. The results and approach will help Ducks Unlimited Canada for conserving wetland and for waterfowl, wildlife and people.

Drinking Water Treatment Infrastructure: Responding to Climate Change and Increasingly Variable Source Water Quality - Year two

As a result of climate change and other pressures that result in “extreme events” like wildfire and flooding, many
drinking water utilities are at risk of potentially catastrophic failure and need treatment adaptation strategies to
prepare for increasingly variable and potentially rapid deterioration in source water quality. Currently there are no
recognized tools for evaluating the anticipated impacts of such events on water treatment plant operations. This
research will enable Stantec Consulting Ltd.

Pool-riffle design for river restora

Professionally practicing Civil Engineers and Earth Scientists engage in stream restoration actions in order to enhance freshwater habitats for salmon, trout, and a variety of other species. There is a wealth of procedures and standards available to help practitioners develop design plans. However, there is a lack of specific guidelines to help identify stream reconstruction details that will give the overall effort a greater likelihood of meeting performance expectations and criteria after the project has been constructed.

Evaluating the impact of workplace indoor environmental quality on employee comfort and wellness

The design and quality of the indoor environment is understood to play an important role in the well-being and productivity of building occupants. While many building and design strategies have been employed to enhance the indoor environmental quality of workplace environments there is a surprising a lack of empirical evidence drawn from buildings in-use that shows how such strategies actually affect occupants.

Soil Vapour Assessment and Ontario Regulation 153/04 Environmental Site Investigations in Ontario

Based on the evaluation of modelled soil vapour concentrations it is common for soil contaminants of concern (i.e., volatile contaminants) to pose a potential health risk to receptors via the soil-to-indoor air vapour migration pathway. However, it is understood that the approach used to model vapour concentrations in indoor air, though acceptable to the Ontario Ministry of the Environment, is highly conservative based on the assumptions related to the maximum soil concentrations and potential for natural attenuation of soil vapours.

A Study on the Durability and Service Life of Concrete Gravity Base Structures (Phase 1, 2)

The project focuses on the development of some HPC mixtures using concrete materials available in Newfoundland. The developed HPC mixtures can be successfully used by concrete suppliers in Newfoundland area especially for the construction of marine and offshore structures. The project also aims to provide data-based analysis on the service life of some local concrete mixtures to be used in gravity base structures.

Identifying dominant anaerobic microorganisms for degradation of benzene

Contamination of soils and groundwater with gasoline often results in the development of anaerobic zones. Benzene is particularly persistent under anaerobic conditions even in the enhanced anaerobic biodegradation (EAB) process. Degradation of benzene has been demonstrated under nitrate-reducing condition, and sulphate-reducing condition. However, information of dominant indigenous species within the microorganisms for degrading benzene is still limited.

Hybrid Biological System for Onsite Wastewater Treatment

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.
