1H-benzotriazoles (BTZs) and their analog compounds are widely used in aircraft de-icing and anti-icing solutions, however their high solubility in water and resistance to biodegradation results in only their partial removal in wastewater treatment, and therefore makes them potential contaminants in watershed systems.  The Wilmington Air Park in Wilmington, OH currently has two surface-runoff lagoons to pre-treat water containing these de-icing compounds before releasing it into area streams.  Because the Wilmington Air Park has recently made an agreement with an online retailer to lease over two dozen planes and open a package-sorting facility beginning in mid-to-late 2019, the goal of this project is to determine the quantity of BTZs that may be present in runoff from the air park’s water treatment beds and establish a water quality baseline before the retailer begins their operations in Wilmington.  Samples were collected from three water sites throughout the winter (January through February) of 2019 and isolated via solid-phase extraction, then analyzed for the presence of BTZs using a quadrupole LC-MS in Single Ion Monitoring detection mode.  The results from the Winter 2019 runoff samples will be compared with those from samples taken in other seasons.
