Micropollutant contamination of water and soil for two biofiltration system treating road runoff

This data includes micropollutant concentrations evaluated in untreated road runoff, water drained from a biofiltration swale, water drained from a vegetative filter strip and the filter media from the biofiltration swale produced on the Compans study site as a part of the Roulépur research project. Sampling and analytical methods are detailed in Field performance of two biofiltration systems treating micropollutants from road runoff and Retention and transport processes of particulate and dissolved micropollutants in stormwater biofilters treating road runoff. Basic characteristics of sampled rain events are provided in "Rain event characteristics," while locations of soil sample collection within the biofiltration swale are provided in the "Location of BFS soil samples."
