Portland - Daycare Center (PDC) Air Monitoring Station, Portland, Oregon

Portland - Daycare Center (PDC) is an air monitoring station located at 2215 SE Gladstone St in Portland, Multnomah County, Oregon. Operated by the Oregon Department of Environmental Quality, the station is part of the broader US EPA Air Quality System (AQS) network, which monitors criteria pollutants and other parameters to assess ambient air quality. The station operates under the regulatory framework of the Clean Air Act and EPA guidelines. In Oregon, air monitoring stations like PDC typically measure pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead. The station's siting follows EPA representativeness criteria to ensure data reflects local air quality conditions. As a community-scale monitoring station, PDC provides critical data for public health assessments and regulatory compliance. Its location near a daycare center underscores the importance of monitoring air quality in sensitive environments. The data supports state implementation plans and informs local air quality management decisions.

Portland's air quality is influenced by a mix of urban emissions, including transportation, industrial activities, and wood smoke from residential heating. The Pacific Northwest's geography and weather patterns, such as temperature inversions, can trap pollutants near the ground. Monitoring stations like PDC help track compliance with National Ambient Air Quality Standards (NAAQS) and support public health advisories. The station's placement in a residential area with a daycare center highlights the need for representative siting to protect vulnerable populations.
