The City of Longmont in partnership with Boulder A.I.R. is conducting a regional air quality study with monitoring stations located at Union Reservoir and Vance Brand Municipal Airport. Data collection at both stations began in late 2019 and data is publicly available in near-real-time at http://www.bouldair.com/longmont.htm. A year’s worth of quarterly data analysis reports are also available on the City’s website at https://www.longmontcolorado.gov/departments/departments-n-z/public-information/oil-and-gas/monitoring-and-reports-oil-and-gas.
