Description

Alberta Environment conducted a mobile air quality monitoring survey near livestock feeding operations in the Lethbridge area from September 1998 to July 1999, in response to concerns voiced by local residents about odours from livestock feeding operations as well as a proposal for a hog processing plant in the Lethbridge area. Following the public release of the Alberta Environment report and a critique by the Chinook Health Region, a request was made by Alberta Environment for this independent review of the Alberta Environment study and the Chinook Health Region critique.

Description

This study investigated the population ecology of grizzly bears in the boreal upland ecoregion in the Berland and Little Smoky rivers area in west central Alberta. Specific objectives of the study were to determine the size, density, productivity and stability of this grizzly bear population. Because grizzly bears occurred sympatrically with black bears, the study also obtained data on the population characteristics of black bears.

Description

Residents of the Calder neigbourhood in Edmonton had concerns with diesel fume impacts on the air quality in the area resulting from a Canadian National rail yard located just south of the neighbourhood. Alberta Environment conducted mobile air monitoring surveys in the winter and summer of 2004 and the winter of 2005. In general, pollutant concentrations in the neighbourhood were not significantly different from concentrations measured at the comparison stations outside the Calder neighbourhood.

Report on Canada Creosote site - North Bow screening level risk assessment update

Description

This follow-up investigation and screening level HHRA update was completed to address data gaps and recommendations outlined in the HHRA previously conducted by Golder in 2010 and 201.... More ≫

Description

This follow-up investigation and screening level HHRA update was completed to address data gaps and recommendations outlined in the HHRA previously conducted by Golder in 2010 and 201. Specifically, the objective of this investigation was to collect additional seasonal groundwater and soil vapour data at the site, and to update the previous HHRA based on this new data. The soil vapour sampling events carried out as part of this investigation targeted times of year when groundwater levels were expected to be at their approximate lowest and the vapour risk was assumed to be at its approximate highest.

Physical mixing patterns of water and contaminants in the North Saskatchewan River

Description

A ten day field campaign was carried out on North Saskatchewan River to study the physical mixing with the ambient river water of effluent from the Goldbar Wastewater Treatment Plant (WWTP), Capital Region WWTP and Agrium Redwater operations. In this report we present rhodamine concentrations, depth averaged water velocities, and flow depths across surveyed sections in reaches downstream of each plant. The objectives of the study were twofold. The primary objective was to determine the downstream distance required to achieve full mixing of the effluent. Full mixing was defined as the location where tracer concentration was uniform across the section. The second objective was to measure spatially distributed tracer concentration and water velocity in the mixing zone, such that dispersion patterns could be determined.

Description

Infectious diseases are one of a suite of factors implicated in the declines and extinctions of amphibians worldwide. One such disease, chytridiomycosis, is caused by the chytrid fungus Batrachochytrium dendrobatidis (Bd). Chytrid fungus was discovered in Alberta in 1999 from necropsies of several specimens of boreal toads and northern leopard frogs collected near Caroline. In late 2006, a pilot-study was conducted to determine whether Bd was present at northern leopard frog sites in southern Alberta. The detection of Bd at multiple sites, and in a provincially Threatened species, led to the expansion of Bd surveillance to other areas of the province, and to other amphibian species between 2007 and 2010. The results, reported in this study, provide a base-line for the occurrence and prevalence of Bd in Alberta. This information is required for the effective conservation and management of a broad suite of amphibian species, many of which are of high conservation concern in Alberta.

Description

The North Saskatchewan River (NSR) watershed in Alberta drains 57,000 square kilometers. The sparsely populated NSR headwaters are at the Saskatchewan Glacier in Banff National Park and are mostly pristine. The river flows more than 1,000 kilometers from its headwaters to the Alberta– Saskatchewan border with an annual outflow of 7.2 billion cubic meters. The NSR joins the South Saskatchewan River and eventually flows into Lake Winnipeg. Water use along the NSR and its tributaries includes human consumption, waste assimilation, hydroelectric power generation, oil and gas extraction, mining, and agriculture. Major dams in the watershed are two hydropower peaking facilities: the Bighorn on the mainstem of the NSR, which forms Abraham Lake and the Brazeau Reservoir on the Brazeau River. Land uses in the watershed include agriculture, resource exploration and extraction, forestry, recreation, urban centers and country residential development. The largest urban area is the Capital...

Synthesis of recent knowledge on water quality, sediment quality and non-fish biota in the North Saskatchewan River with special emphasis on the Industrial Heartland-Capital Region Water Management Framework reach

Description

The main objective of this report is to provide a succinct overview of the technical studies conducted in support of the Water Management Framework for the Industrial Heartland-Capital Region (IH-CR). The IH-CR supports a population of over one million people and a large segment of Alberta’s resource processing heavy industry, and the region is expected to continue to experience industrial and population growth. Unless this growth is managed carefully, cumulative impacts on the river from point and non-point source loading of contaminants could lead to the deterioration of water quality and aquatic ecosystem health. The Water Management Framework for the IH-CR focuses on the management of current and future municipal and industrial impacts.

Description

Over the past three years, the Working Well pilot program has delivered community-based workshops, information resources and community outreach to private water well owners. These program elements have ranged in audience reach and scale, some in local communities (workshops) and others being province-wide (information resources).
