Sacramento-Del Paso Manor Air Monitoring Station, Arden-Arcade, California

Sacramento-Del Paso Manor is an air monitoring station located in Arden-Arcade, California, within Sacramento County. It is part of the NCORE (National Core) network, a multi-pollutant monitoring network established by the U.S. EPA to support long-term air quality trends and health research. The station is operated by the Sacramento County Air Pollution Control District (APCD) and remains operational as of June 2025. The station operates under the U.S. EPA's Air Quality System (AQS) framework, which sets standards for criteria pollutants such as ozone, particulate matter, carbon monoxide, nitrogen dioxide, sulfur dioxide, and lead. NCORE stations typically measure a comprehensive suite of pollutants, including speciation and meteorological parameters, to provide a detailed picture of air quality. The Sacramento region, part of the Sacramento Valley air basin, experiences elevated ozone and PM2.5 levels due to vehicle emissions, industrial activity, and geographic conditions that trap pollutants. Sacramento-Del Paso Manor contributes to the regional air quality monitoring network, supporting public health advisories and regulatory compliance. Its data helps inform local air quality management strategies and provides critical information for communities in the Arden-Arcade area. The station's long-term operation ensures continuity in tracking air quality trends and evaluating the effectiveness of emission reduction programs.

The Sacramento region faces air quality challenges from transportation, agriculture, and industrial sources, with ozone and fine particulate matter being primary concerns. The NCORE network, including this station, provides high-quality data on criteria pollutants and air toxics, supporting the U.S. EPA's regulatory framework. Siting representativeness is critical for capturing urban and suburban exposure patterns, and the station's location in Arden-Arcade offers insights into a mixed residential-commercial area.
