The DNR Ambient Air Monitoring group organizes and plans air monitoring activities within the State of Iowa. Federal monitoring requirements are set by EPA. DNR contracts with the State Hygienic Laboratory at the University of Iowa (SHL), along with the Polk and Linn County Local Programs, to collect air monitoring data, quality assure the results, and report the data to the public. Group members administer contracts, perform data analysis and assist in monitor siting.
