Safe drinking water supply is a daily need but it can be seriously threatened by microbial hazards originating from fecal contamination of source water, especially following periods of intense rainfall. In order to assess drinking water intakes (DWIs) vulnerability to fecal pollution and to take cost-effective decisions in case of hazardous events, it is urgent to implement early-warning systems. A recent enzyme-based technology, ColiMinder® enables to measure E. coli in water at high temporal resolution (every 15-30 minutes).
Harmful algal blooms (HABs) in the western basin of Lake Erie are detrimental to the ecosystem, reducing water quality and affecting drinking water for people in the region. Severe HABs in Lake Erie in the 1960s and 1970s resulted in the Great Lakes Water Quality Agreement in 1972. Since then, water quality has greatly improved; however in the 1990s, Lake Erie saw the blooms return. This has been attributed to factors such as zebra mussels bio-transforming nutrients, climate change, shifts in the form of phosphorus and lake sediment as an internal loading source.
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.
Wave uprush and the potential for flooding are natural hazards that must be determined by the Cataraqui Region Conservation Authority (CRCA) prior to the approval of a near-shore development. The purpose of calculating wave uprush is to recommend building sites that are outside of the wave uprush area (and floodplain in general) to land owners and municipalities, as well as provide information for flood proofing of existing buildings, roadways, etc. The CRCA has manually calculated wave uprush at 200 sites along the more than 200 km of shoreline in eastern Lake Ontario and the St.
Pacific salmon play an important economic, ecological, and cultural role throughout their range. However, declining salmon populations have diminished this role in many regions. The factors responsible for declines are poorly understood but are of great interest, particularly for First Nations, who have a large role in salmon management.
In British Columbia, highly saline waste water produced as a by-product of oil and gas operations are injected into deep geological formations via injection wells. The purpose of this research project is to investigate whether or not these injected fluids remain at depth as intended or rather, can return to the surface and contaminate water resources. In particular this project aims to evaluate the role that surrounding active and abandoned wellbores play in acting as vertical conduits for subsurface fluids to leak to the surface.
Grizzly bears represent a valuable economic, ecological, cultural and symbolic resource for British Columbia. In order to preserve this resource the current population of brown bears needs to be monitored to ensure the health of the population. One marker of health is the genetic health of the population. Genetic monitoring can also tell us important information about how related different bear populations are and how well these populations are adapted to their ecosystem.
Atlantic Gold is preparing to start construction for an open pit mine near the city of Halifax, Nova Scotia. However, significant wetlands will have to be altered to complete this construction. The current policies regarding wetland alteration and compensation in Nova Scotia focus on area. For example, if 25 hectares of wetland are to be altered, it is required that Atlantic Gold will have to create 50 hectares of new wetland to compensate.
Rivers in much of eastern Canada flow through regions comprised of cohesive glacial sediments, including glaciomarine clays and glacial tills. Given the glacial history of Canada, many if not most of its rivers can be characterized as semi-alluvial.
Management of these rivers in terms of sediment load is a difficult challenge, because relatively little is known about their stable channel geometry.
Predicting the quantity of mineral (gold, coper, etc) or hydrocarbon (oil, gas) extracted from a given deposit is difficult. One concern is the uncertainty in the resources underground. A few initial wells or drill holes give us access to an estimate of the quantity of resource, but there is great uncertainty because sampling can be hundreds of meters or kilometers apart.
