Houston Area Air Monitors

Houston ranks #1 in the number of air monitors in the nationAir monitor equipment samples outdoor air.There are 48 ozone monitors in the Houston-Galveston-Brazoria (HGB) area operated by the TCEQ, City, Harris County, HRM, or independent sources There are 32 monitors that measure hazardous air pollutants (HAPs) in HGB

2. To attain this standard, the 3-year average of the 98th percentile of 24-hour concentrations at each population-oriented monitor within an area must not exceed 35 ug/m3.

3. Source: EPA Air Data and TCEQ DSR data base.

4. Special note: No correlation factor between FRM and FEM monitors was considered for TEOM data before 2007.

1. To attain this standard, the 3-year average of the weighted annual mean PM2.5 concentrations from single or multiple community-oriented monitors must not exceed 15.0 ug/m3.

In Summary

The Greater Houston Area is the most heavily monitored area in the US.

Houston’s air quality has dramatically improved and will continue to improve. Evidenced by the fact:

Exceedances of the ozone NAAQS continues to declineAnnual average PM2.5 levels are declining at area monitors
