This report describes an air quality analysis for the Denver metropolitan region for the years 1976, 1985, and 2000. The analysis was carried out to provide background information as to the environmental impact of the urban growth that might be associated with the availability of new wastewater treatment facilities. Generally improving air quality is forecast, although exceedances of some air quality standards are projected. These results are based on physico-chemical computer simulations, using pollutant emissions forecasts. Projections of photochemical oxidant concentrations, exposures, and dosages were obtained with the Denver Air Quality Model. Air quality projections appear to be negligibly affected by major changes in projected land use and less than proportionately affected by large changes in atmospheric dispersion. Measures proposed to mitigate adverse air quality are examined.
