Description

The Alberta River Water Quality Index was developed as a way to summarize physical, chemical and biological data into a simple descriptor of water quality. The index is based on values annually for four variable groups: metals, nutrients, bacteria, and pesticides. This record includes the overall water quality index in chart format for all major river systems in the province.

Description

Coalbed gas (CBG) effectively consists of methane with minor amounts of ethane and propane, but no hydrogen sulphide (H2S). Recognition of CBG as an increasingly important energy resource has led to rapid expansion of exploration activity. Rapid development started in the 1980s in the western United States of America (USA), and has spread over the last six years to the Western Canadian Sedimentary Basin (WCSB). Increased production activities have brought increased awareness of environmental issues surrounding CBG development. In particular, reports of negative experiences associated with early CBG development in the USA have raised stakeholder concerns in Canada. Alberta CBG development has largely avoided the water resources issues experienced in the USA from CBG exploitation for two reasons. The major CBG resource plays in Canada to date have been in ‘dry’ coals, while ‘wet’ CBG coals developed in the USA required dewatering in order to recover the gas. Secondly, the rapid...
