Air quality is a main focus of the Oil and Gas Chapter of Broomfield’s Comprehensive Plan.  Broomfield created the Air Quality Monitoring Program (AQM) to help protect the health of the residents, environment, and wildlife. 

Please visit Broomfield Public Health’s Air Quality page for information on ozone and today’s air quality conditions.

Air Quality Monitoring Program Details

View a map of the air quality monitoring sensors and the trailer locations. The locations of the sensors and stationary trailer locations were selected by a team of atmospheric scientists, based, in part, upon meteorological data and elevations. Sites near oil and gas well sites were selected to capture emissions prior to dispersion and in the neighborhoods to determine if pad emissions are moving into residential areas.  If any oil and gas operator is found to be responsible for an illegal release of emissions, citation or further legal action will be considered. Although the data from this system is carefully monitored and shared as necessary with emergency responders, this system is not intended to be an emergency response protocol nor an acute exposure warning system. Broomfield staff will publish trigger notifications and data as soon as it can be validated.  Other real-time data is available on the links below.

Air Quality Monitoring Program Monitoring Equipment

The AQM, which includes equipment and analysis of data by Colorado State University (CSU), Ajax Analytics & Boulder A.I.R.  The following equipment monitors oil and gas emissions (VOCs):

  • APIS sensors with real-time trigger canisters that collect air samples for laboratory analysis when triggered by elevated total volatile organic (TVOC) emissions.  Analysis of the trigger canisters allows for identification of individual compounds & concentrations. The trigger canisters are in operation at 10 locations both near oil and gas well pads and in adjacent neighborhoods. They detect over 800 compounds and results of the canister samples are analyzed by scientists at the Atmospheric Sciences Lab at Colorado State University and all canister results are made public when received. View a timeline of the trigger canister process.

  • CSU’s photo mass spectrometer (PTRMS) which is located at the Soaring Eagle site and provides real-time data of volatile organic compounds.

  • Two Stationary monitoring stations, which provide real-time data of volatile organic compounds, including oil and gas signature emissions, like benzene, and ozone data.

  • Since 2018, the CDPHE placed its mobile air monitoring laboratory (CAMML) in Broomfield at a location that is northwest of the Livingston Pad.  The CDPHE continues to return the CAMML to do follow-up testing during hydraulic fracturing and flowback phases and is currently taking data at the Livingston Pad for a number of weeks.  That information is also used in Broomfield’s AQM and is considered in the Quarterly Reports.

How to view data

  • Ajax Analytics Site.  To view the Ajax TVOC live data portal near the Livingston pad, from the website:

    • On the map, click on the brown Livingston Pad icon.  The TVOC data from the stations closest to the pad will show below the map.

      • (Normal range is shown in green on the graphs - between 80-200 mV.   An air quality event may be identified by a sustained & elevated - 2x to 5x normal range - TVOC reading from one or more stations.)

  • Boulder A.I.R. This site provides real-time data of volatile organic compounds and other airborne compounds, such as methane and nitrous oxides. In the near future, the site will feature other real-time data for oil and gas signature compounds, including benzene.
