This review synthesizes current knowledge on water and soil pollution attributed to drainage of conventional rail transportation infrastructure (RTI) considered in three categories: (i) tracks and associated structures, (ii) rail yards, and (iii) passenger stations. Pollutants arise from rolling-stock operation, rainwater washoff of infrastructure materials, and maintenance. Resulting runoff can convey metals, polycyclic aroma...

Urban areas are affected by anthropogenic activities that cause pollutant load on receiving water bodies. Stormwater bioretention are popular and effective in removing pollutants. The main water quality treatment processes are filtration and adsorption in the top layer (0-10 cm) of the filters. So far, few in-field studies have evaluated effects of cold climate and de-icing salt on bioretention for treating metals. Thus, a com...

The water quality implications of transferring stormwater through pipes composed of concrete (new and used), polyvinyl chloride (PVC), galvanized corrugated steel (GCS), high-density polyethylene (HDPE), and pipes subjected to cured in place pipe (CIPP) and spray in place pipe (SIPP) trenchless repair technologies on stormwater quality are reviewed. Studies involve either the use of flowing water or an immersion experimental d...

Urban stormwater typically enters sewer networks through gully pots, which allow a primary sedimentation of solids upstream of the piped network. The regular removal and disposal of retained sediment are necessary, costly and can involve environmental risks due to the contamination of sediments with substances from the urban environment such as metals. The concentrations and speciation of Cd, Cr, Cu, Ni, Pb and Zn were analyse...
