An evaluation of wastewater treatment technologies for the purpose of recirculation in aquaculture facilities with a focus on an unsubmerged bioreactor
(2017-07-14)As aquaculture continues to grow worldwide, land-based aquaculture facilities can be ideal because a large volume of fish can be produced in a small area. With growth comes the concern of water usage and wastewater management. ... -
An investigation into the influence of slope on trail erosion and the effects of trails on plant communities within Garry Oak and associated ecosystems in Mount Douglas Park, Vancouver Island
(2018-03-19)Urban parks provide refuge for species at risk, and maintain and preserve biodiversity in densely populated settings. Soil erosion on trails, which can have negative impacts on the surrounding plant communities, is a growing ... -
An investigation of carbon sequestration, storage capacity, and air pollution removal by trees in the Resort Municipality of Whistler
(2022-08-05)Trees have a considerable ability to reduce atmospheric carbon dioxide and improve air quality, including many other valuable ecosystem services. Beyond timber value, trees contribute to other economic benefits that are ... -
Anaerobic digestion enhancement : impact on the volatile solids reduction and biogas production within municipal anaerobic digestion systems via routine bioaugmentation with a biocatalytic microbial and enzyme consortium
(2020-12-02)Wastewater Treatment Plants (WWTPs) frequently use anaerobic digestion (AD) to break down organics to reduce the total volume of biosolids produced. As population increases, cost of biosolids disposal increases while ... -
An analysis of a sustainability multi-critera analysis tool at contaminated sites in the north.
(2013-02-26)Sustainable remediation aims to address the legacy of poor past environmental practices without further impacting the environment. A sustainable decision support tool is under development to guide the selection of sustainable ... -
An analysis of environmental regulatory compliance
(2014-12-05)The future of North American energy supplies lie in a source of unconventional gas known as coalbed methane (CBM). As with any hydrocarbon resource, its exploration and production poses risks to the environment that can ... -
Applicability of a delta portable XRF spectrometer for determining geochemistry of glacial sediment samples collected in the Canadian Western Arctic
(2016-01-28)The performance of Royal Roads University's Delta Premium DP 6000 portable X-ray fluorescence spectrometer (Delta pXRF), specifically its accuracy and precision, was assessed on two certified standards for select elements. ... -
Aquatic health effects of biotechnical streambank restoration of the Elbow River in an urban environment
(2019-09-17)Streambank stabilization that uses non-living and living design elements, called biotechnical restoration, is an increasingly common approach to stream restoration design. With this increase in use, it is important to ask ... -
Assessing GBA+ as a tool for climate justice
(2023-01-31)In 2018, British Columbia’s (BC) provincial government released CleanBC, and in 2021 BC released the Roadmap to 2030, two cross-ministry efforts to reduce greenhouse gas emissions and build a green economy. While governments ... -
Assessing the effectiveness of physical treatments to control non-native spartina patens in a constructed marsh in Port Moody, British Columbia
(2015-03-25)Field trials were conducted at a constructed salt marsh in Port Moody, British Columbia to test the following physical control variations for their effectiveness at reducing non-native <italic>Spartina patens</italic>: ... -
Assessing the fate of lake recovery in an urbanizing watershed : an application of an extrapolative static phosphorus loading model to Langford Lake, BC
(2010-06-15)A static phosphorus loading model, as proposed by G.K. Nurnberg (1998, Limnology and Oceanography, 43, 1544-1552) is applied to Langford Lake, BC to determine the likely sources of phosphorus entering the lake and to predict ... -
Assessing the impact of human activities on British Columbia's estuaries
(2013-08-01)The world's marine and coastal ecosystems are under threat and single-sector management efforts have failed to address those threats. Scientific consensus suggests that management should evolve to focus on ecosystems and ... -
