City-Provided Air Quality Monitoring Services (September 2021 – Present)
After five years, South Coast Air Quality Management District (SCAQMD) completed the world’s most extensive hexavalent chromium air monitoring program in Paramount in mid-2021 (click here to see all SCAQMD monitoring results). On September 21, 2021, the Paramount City Council, aware of the importance of continued monitoring for the health of the community, unanimously voted to pay for air monitoring services in a contract with T and B Systems, which has since joined Trinity Consultants.
T and B Systems will continue taking air samples on a weekly basis throughout the City to monitor levels of hexavalent chromium. To see the archived results beginning from November 2021, click here. For a running log of current monitoring results in 2023, click here. Note: The date displayed in the table below only reflects currently active monitors.
Occasionally, filters may be considered invalid if the sampler operation is found outside of the recommended calibration criteria, there are power outages, rainwater impacts the filter or the filter is damaged.
