Abstract
The Federal Clean Water Act requires the Iowa Department of Natural Resources (IDNR) develop a pollutant total maximum daily load (TMDL) for waterbodies on the state’s impaired (303d) waters list. Yeader Creek has been assessed as impaired by priority organics, specifically propylene and ethylene glycol. The purpose of this TMDL is to estimate the maximum glycol loading that can be delivered to the stream while meeting water quality standards. Propylene glycol and ethylene glycol are chemicals used in the deicing of aircraft at the Des Moines International Airport (DMIA). Airport drainage forms the headwaters of Yeader Creek and is associated with the Yeader Creek impairment.
