Description

The GoA is committed to a vision of a vibrant and prosperous province where Albertans enjoy a superior quality of life and are confidence about the future for themselves and their children. Safe and adequate supplies of water, clean air and land, together with healthy, dynamic communities are the foundations of a high quality of life. All Albertans share responsibility for stewardship of the environment and the responsible use of our natural resources. As part of its mandate, Alberta Environment and Sustainable Resource Development is responsible for working with Albertans to ensure that environmental quality is maintained and that natural resources are used responsibly.

Description

The burrowing owl is listed as an 'endangered' species in Canada by the Committee on the Status of Endangered Wildlife in Canada. The species is now considered extirpated from both Manitoba and British Columbia, and populations continue to decline in Alberta and Saskatchewan. In Alberta, surveys for burrowing owls have been conducted since 1991 near Hanna, and since 1993 near Brooks. These surveys, conducted in permanent blocks, are an ongoing commitment of Alberta Environment to determine the population status of Borrowing Owls in Alberta, in part to fulfill commitments made to the National Recovery Plan for the Burrowing Owl, and to provide information to the Alberta Endangered Species Conservation Committee. Knowledge of the population trend is essential for status designation, and continued population monitoring fundamental to the conservation of burrowing owls.

Description

This study delineates flood hazard areas and determines design flood levels along an approximate 31 km length of the Highwood River through High River. The design discharge for the Highwood River ranges from 750 m³/s at the upstream study extent to 650 m³/s at the downstream extent. Included in the study area are lands flooded by overflow from the Highwood River into the Little Bow River via Baker Creek and the Little Bow Canal, along approximately 3 km of Baker Creek and almost 1 km of the Little Bow River. The flood hazard mapping in a portion of the overflow area and along the Little Bow River is currently under review by Environment and Sustainable Resource Development. The study was prepared in August 1992. Flood information available after study completion may not be reflected in the current flood hazard study report or flood hazard mapping.

Description

The objective of this report is to present historical information and data concerning the floods int he North Saskatchewan River Basin. It is the intent to provide in one report the most salient flood data and information which may be available in any of the several existing publications. There are currently about sixty hydrometric stations active in the North Saskatchewan River Basin. This report presents data for eighteen selected hydrometric stations. Streamflow data have been collected for the North Saskatchewan River for approximately seventy years and there are several publications which give the recorded flood data in various forms.

Description

A subsurface investigation at a reclaimed sanitary landfill in Edmonton (Beverly) has revealed that combustible gases entering a golf course structure are generated from decomposing garbage in the old landfill. Gases containing methane up to a maximum of 83% by volume are present in the subsurface adjacent to the structure. A ventilation system beneath the building maintains the methane concentration at less than 50% of the lower explosive limit (2.5 volume percent). The atmosphere beneath the structure is monitored continuously for combustible gases; an automatic alarm system will be activated should methane concentration exceed 50% of the explosive rate. Based on the results of this investigation, it is apparent that a large reservoir of combustible gas is present within the reclaimed landfill site. It is probable that the methane monitoring/warning system, and the ventilation system must remain operative for a period in the order of 50 years or more.

Description

Subdivision of the area surrounding the Hamlet of Anzac is in the preliminary phase of planning. The Soils Branch was requested by the Land Tenure Secretariat of the Department of Municipal Affairs to test soils in order to help plan the subdivision for residential use. The work involved test drilling for watertable and percolation tests. Forty holes were drilled with a truck mounted auger. The soil near the surface is either sandy or silty clay till. Most of the area has a high water table. The area has limitations for basement construction and normal sewage disposal septic fields.

Description

Physical and chemical analysis of spent sand indicate that this material is very infertile. The spent sand samples analysed had an average pH of 7.2 and low Na content indicating that there was no residual problem resulting from the NaOH used in the oil production process. Freshly processed sand however does have a high pH and higher Na contents.
