Collecting water sample of a tributary of Oak Creek in Milwaukee, Wisconsin in winter
Detailed Description
Owen Stefaniak collects a water sample of a tributary of Oak Creek, in Milwaukee, Wisconsin. The tributary is locoated at the southeast corner of General Mitchell International Airport property, just outside the perimeter fence. The airport runway is visible beyond the fence.
Samples are analyzed for a variety of water quality parameters, but the main parameters are propylene glycol (the active freezing point depressant in aircraft deicers/anti-icers), acetate (a component in pavement deicers), and chemical oxygen demand (which helps us determine how pollution will impact the oxygen levels in the stream).

Chemicals used to deice planes at General Mitchell International Airport in Milwaukee may be entering nearby streams in concentrations that may be harmful to aquatic life. This project will investigate the toxicity of decing chemicals, evaluate their impact on receiving streams, and assess changes in water quality in response to the implementation of deicer management at General Mitchell Airport.

Deicing an airplane at Milwaukee airport
Two technicians deicing a plane at Milwaukee General Mitchell International Airport in winter. They are applying Type I aircraft deicer (which is orange) to the plane. Type I deicer is typically applied hot (hence the steam) and it is used to remove existing ice and snow. This will then usually be followed with Type IV (which is green) to prevent new ice.

Airplane parked at hangar after deicing
A technician has just finished applying Type IV aircraft anti-icing fluid (which is green) to an airplane parked at a hangar. Anti-icing fluid is applied after the plane has already been deiced and it is used to prevent new ice from forming. Type IV fluid typically shears off the fuselage during takeoff and can be deposited along runways.

Water sample bottle at Wilson Park Creek in winter
James Romano holds a water sample collected at the end of Wilson Park Creek in Milwaukee, Wisconsin. The creek drains into the Kinnickinnic River, which eventually reaches the Milwaukee Estuary and Lake Michigan. Samples there are analyzed for same parameters as all the other sites.
