Overview
Boulder Reservoir is an operational air monitoring station in Boulder, Colorado, managed by the Colorado Department of Public Health and Environment. It contributes to the US EPA Air Quality System network.
Boulder Reservoir is an air monitoring station located at 5545 Reservoir Road in Boulder, Colorado, United States. Operated by the Colorado Department of Public Health and Environment, it is part of the national ambient air quality monitoring network. The station provides critical data on criteria pollutants to support regulatory compliance and public health assessments. The station operates under the US EPA Air Quality System (AQS) framework, which sets standards for monitoring methods, quality assurance, and data reporting. As part of Colorado's monitoring network, it helps track air quality trends in the Front Range region, which faces challenges from urban emissions and mountain-valley meteorology. The station's last reported sample date is September 30, 2025, indicating ongoing data collection. Boulder Reservoir's location near a major water body and recreational area makes it valuable for assessing air quality in a mixed urban-natural setting. The data supports state implementation plans for National Ambient Air Quality Standards (NAAQS) and informs local air quality alerts. Its continued operation ensures long-term trend analysis for the Boulder Valley.
Environmental context
Boulder Reservoir's air monitoring station is situated in a region influenced by both urban pollution from the Denver-Boulder metropolitan area and natural emissions from forests and agriculture. The station's siting near a reservoir provides representative data for a suburban interface zone. Monitoring typically includes criteria pollutants such as ozone, particulate matter, and nitrogen oxides, which are key for assessing compliance with EPA standards. The data contributes to understanding local air quality dynamics, including the impact of wildfires and temperature inversions common in Colorado's Front Range.
