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

Presents an enhanced sampling design for deployment in the Lower Athabasca River. It represents one component of work to describe baseline environmental conditions in the Lower Athabasca River prior to the potential release of coke slurry-treated oil sands process affected water (OSPW). The document describes sampling locations and sampling frequency to establish a comprehensive description of baseline environmental conditions in surface water chemistry, benthic sediments, benthic algae, benthic macroinvertebrates, and small-bodied fish.
