Water and air quality trends and status for the calendar year 1978 were determined for the six states in Region VIII. These states are Colorado, Montana, North Dakota, South Dakota, Utah, and Wyoming. Data resident in EPA national data banks (STORET, SAROAD) were analyzed. Statistical tests which detect significant differences between two populations were utilized to show trends in both air and water quality. The status and severity of stream pollutants were determined by relating parameter concentrations to Water Quality Indicator (WQI) values on a numerical scale from 0 to 100. The status and severity of air pollutants reported continues to be a direct measure of air quality standard and alert level exceedences.
