Environmental GIS Intern project: how to find potential pollutants entering stormwater drains through runoff with ESRI GIS tools?

I am an intern at a port authority and my supervisor has told me to get creative about how to solve this: the purpose is to figure out which drains have the highest priority to apply drainage filters, and then what kind of filter does it need.

I have shape files of parcels (so that I can tell who uses the property), inlets, outlets, Pipeline and an elevation raster. I was thinking of inputting the material levels into the parcel attribute table of the parcels that have stormwater drainage permits and running arc hydro tools on the raster to find flow direction. Kind of stumped on further analysis/ where to go from there or if I’m even on the right track
