Chloride in surface waters of Alberta’s rivers : condition of the environment report 2021

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... More ≫

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

This report presents an analysis of available data and literature to gain an understanding of effluent quality in the Upper Athabasca River. Based on this analysis, variables of concern were identified and recommendations for future effluent monitoring programs were developed. The study compiled, analyzed and evaluated data and information on effluent quality from two municipalities, two coal mines and five pulp mills discharging into the mainstem Athabasca River in the Upper Athabasca Region.

Description

The report presents results of a water quality monitoring program completed on the Athabasca River. During the winter of 2015, Alberta Environment and Parks conducted a synoptic survey on the Athabasca River. The purpose of the study was threefold: to evaluate winter spatial patterns in water quality along the length of the Athabasca River; to assess the cumulative effects of industrial and municipal point-source discharges on the Athabasca River during winter low flow, while considering contributions from major tributaries; and to compare current water quality conditions in the Athabasca River to data collected in 1990-1993. A synoptic survey is a comprehensive spatial survey that aims to sample the same ‘parcel’ of water as it flows downstream in a river basin.
