About
Andrew Tirpak, PhD, P.E., is an Assistant Research Professor in the Department of Food, Agricultural, and Biological Engineering at The Ohio State University. His research has focused on quantifying the impact of green infrastructure practices at the site and watershed scale, evaluating technologies to mitigate construction site runoff, developing low-cost sensor networks to facilitate real-time monitoring of urban hydrology, and investigating methodologies to improve the performance of stormwater control measures. His experiences include desktop modeling, controlled laboratory studies, and field scale assessments of a variety of urban stormwater controls, including bioretention, permeable pavement, retention and detention ponds, and floating treatment wetlands. He received his PhD from the University of Tennessee in 2018, where he conducted research on the role of trees in green stormwater infrastructure practices and means to enhance the resilience of urban stormwater controls to climate change.

PFAS concentrations of <0.03-19 and 0.064-16 μg/kg-DW, respectively. Unknown C6-8 PFCA precursor concentrations were up to ten times higher than the corresponding PFCAs, especially at forebays and biofilters' top layer. No significant trend could be attributed to PFAS and precursor concentrations versus depth of filter media, though PFAS concentrations were 2-3 times higher in the upper layers on average (significant difference between the upper (0-5 cm) and deepest (35-50 cm) layer). PFASs had a similar spatial concentration distribution in each filter media (no clear difference between short- and long-chain PFASs). Commercial land use and organic matter were important factors explaining the concentration variations among the biofilters and between the sampling depths, respectively. Given the comparable PFAS accumulations in deeper and superficial layers and possible increased mobility after precursor biotransformation, designing shallow-depth, nonamended sand biofilters or maintaining only the top layer may be insufficient for stormwater PFAS management.
