Overview
Hanford-Irwin is an operational air monitoring station in Hanford, California, operated by the San Joaquin Valley Unified Air Pollution Control District. It provides ambient air quality data as part of the US EPA Air Quality System network.
Hanford-Irwin is an air monitoring station located at 807 South Irwin Street in Hanford, California, within Kings County. The station is part of the San Joaquin Valley Unified Air Pollution Control District's monitoring network and contributes to the US EPA Air Quality System (AQS). It is operational and collects ambient air quality data to support regulatory compliance and public health protection. The station operates under the regulatory framework of the US Clean Air Act and the EPA's AQS network, which sets standards for criteria pollutants such as ozone, particulate matter, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. Monitoring stations like Hanford-Irwin typically measure a subset of these pollutants along with meteorological parameters. The San Joaquin Valley is known for its air quality challenges due to geography and emissions from agriculture, transportation, and industry. Hanford-Irwin plays a key role in regional air quality management by providing continuous data that informs regulatory decisions and public health advisories. Its location in the San Joaquin Valley, a non-attainment area for ozone and particulate matter, underscores its importance in tracking pollution trends and evaluating the effectiveness of emission reduction strategies.
Environmental context
The San Joaquin Valley faces significant air quality challenges due to its topography, which traps pollutants, and emissions from agricultural operations, vehicle traffic, and industrial sources. The region is designated as a non-attainment area for ozone and fine particulate matter (PM2.5) under the US Clean Air Act. Air monitoring stations like Hanford-Irwin are critical for measuring pollutant concentrations, assessing compliance with National Ambient Air Quality Standards (NAAQS), and supporting public health advisories. The station's data contributes to the EPA's Air Quality System (AQS) and helps track long-term trends in air quality.
