FAP’s 2019 fourth quarter Air Quality Health Index (AQHI) results show that there was only one hour of a high rating and no very high ratings. The one hour of high rating occurred at our Gibbons air monitoring station. There were no exceedances of the 24 hour ambient objectives in Q4 of 2019 and only two one-hour exceedences, one involving fine particulate matter and one involving hydrogen sulfide. The causes were both undetermined. Read the full Q4 report.
As a comparison, the next table shows the results from the fourth quarter of 2018.
