Water quality trends and status for the calendar year 1979 were determined for the six states in Region VIII. These states include Colorado, Montana, North Dakota, South Dakota, Utah and Wyoming. Statistical tests which detect significant differences between two populations were utilized to show trends in water quality. The status and severity of stream pollutants were determined by comparing observed parameter concentrations to state Water Quality Standards or recognized criteria.
