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

The McLeod River headwaters originate in the Rocky Mountains in west-central Alberta and join the Athabasca River near Whitecourt. Coal mining has occurred in the McLeod watershed since the 1970s and more recently, there has been both reclamation and expansion of mine sites in the upper basin. In this study, trends in surface water quality parameters in the McLeod River watershed were assessed over time to understand changes in water quality and associations with active mining and reclamation activity.
