Water and air quality trends and summaries were determined for the six states in Region VIII. These states are Colorado, Montana, North Dakota, South Dakota, Utah, and Wyoming. Only the data on EPA's national data banks were used. The STORET data bank was used for the water quality analysis and the SAROAD base was used for the air analysis. The water quality status and trends were calculated and reported in two ways; (1) as single parameter percentages of standard or criteria violations, and (2) as a single 'index' number derived as the aggregate of percentage violations of four parameter groups. The air quality report provides information where quality standards are achieved as well as areas which still have significant problems. Indices are used where appropriate. This report was not intended to be a comprehensive analysis of cause and effect relationships.
