River Water Quality Index, Alberta

This Alberta Official Statistic describes how the River Water Quality Index (RWQI) for Alberta provides a general assessment of water quality at 28 Long-Term River Network (LTRN) sites on the province’s major river systems. In most cases, the sites represent conditions upstream and downstream of areas of significant human activity. The RWQI has been reported as a performance measure in the Ministry of Environment and Parks "Annual Report" since 1996.
