The Iowa Quad Cities achieved the dubious distinction earlier this week as the first metro area in Iowa to exceed the new, tougher health standard for ozone pollution.
The Iowa Department of Natural Resources (IDNR) reported Tuesday (6/14) the air monitor at Scott County Park, north of Davenport, recorded an 8-hour average for ground-level ozone (O3) of 71 parts per billion (ppb) Monday, June 13. The ambient air quality standard for ozone was lowered to 70 ppb from 75 ppm last December.
