Greeley - West Annex Bldg Air Monitoring Station | Greeley, Colorado Environmental Monitoring

Greeley - West Annex Bldg is an air monitoring station located at 905 10th Ave. in Greeley, Colorado, within Weld County. Operated by Eastern Research Group, this facility is part of the broader US environmental monitoring network that tracks criteria pollutants and other atmospheric parameters to protect public health and the environment. The station operates under the US EPA's Air Quality System (AQS) framework, which sets standards for monitoring methods, siting, and data reporting. While specific parameters measured are not detailed, typical stations in this network monitor pollutants such as ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide. The station's location in an urban area suggests it provides representative data for population exposure assessment. As part of Colorado's air monitoring network, this station supports state and federal compliance with the Clean Air Act. Data from such stations inform air quality index reports, regulatory decisions, and public health advisories. The station's ongoing operation ensures continuity of long-term air quality trends in the Front Range region, which faces challenges from urban growth and industrial emissions.

Greeley is situated in the South Platte River Valley, an area with significant agricultural and industrial activity, including livestock operations and energy production. Air quality in the region can be affected by ammonia emissions from agriculture, volatile organic compounds from oil and gas operations, and particulate matter from dust and wildfires. The monitoring station's location in an urban setting helps capture population-relevant exposures. Parameter coverage typically includes criteria pollutants, but speciation and meteorological measurements may vary. Siting representativeness is crucial for accurate air quality assessment in this mixed-use environment.
