Description

This report presents the methods used to generate the web-based Condition on Environment (CoE) content published for chloride (Cl-) concentrations in the surface water of major rivers and their tributaries across Alberta. Accordingly, this report helps fulfill the responsibility of reporting to the public on the condition of Alberta's ambient environment, as required by the province's Environmental Protection and Enhancement Act. In particular, this report outlines the steps taken to obtain and prepare the data, assess the quality of the data and conduct spatial and temporal analyses of Cl-. The goal of this report is to neither investigate nor summarize potential Cl- sources, but rather to summarize spatial and temporal trend of Cl- concentrations in the surface waters of Alberta's major rivers and tributaries.

Description

Alberta Environment and Sustainable Resource Development (ESRD) has developed environmental management frameworks for air quality and surface water quality under the South Saskatchewan Regional Plan. These frameworks are designed to maintain flexibility and proactively manage the cumulative effects of human activity on ambient air quality and surface water quality within the South Saskatchewan Region. The frameworks do not replace existing regulatory processes. They contribute to managing growth pressures on air, land and water over the coming decades, adding to and complementing existing policies, legislation, regulations and management tools. The frameworks are policy documents that will be given legal authority as specified in the regional plan, and through the mandates and legislation of Environment and Sustainable Resource Development and, potentially, other government departments.
