Enhanced Monitoring - Phase 2
Date range of monitoring: August 2020 – November 2021
In August 2020, the District deployed more advanced monitoring equipment to collect detailed air quality information and determine in which area the portable laboratory should be sited. These sites measures black carbon, toxic metals, and toxic gases (also called volatile organic compounds, or VOCs). A map of the Phase 2 monitor locations is available (here).
Black carbon is measured hourly while toxic metals and VOCs are 24 hour samples, measured every six (6) days. Samples collected are sent to an air quality laboratory to determine the concentrations of specific pollutants. Phase 2 monitoring ended November 2021. Data is posted after it has been validated and processed.
