Sources and characterization of stormwater pollutants
The building wash-off and its quality have been addressed during the past 30 years, but mostly with respect to heavy metals in roof drainage. In this project, a general suite of chemical substances and their wash-off and transport will be addressed, including for example metals and trace organics identified as priority pollutants, and pollutants of emerging concern.
DRIZZLE’s studies examine these processes at various scales, starting with lab scale studies, continuing with pilot scale studies, field studies, and later at sub-catchment level. The results from these studies will allow for the recommendation, prescription, and selection of environmentally sound building materials.
In order to understand how stormwater pollutants will spread in the environment, and in order to support the development of adapted stormwater treatment solutions, knowledge on metals’ size fractionation is important. LTU is conducting field studies on sites with different land use characteristics, such as a car park, industrial parks. The stormwater from these sites are analysed with respect to the size fractionation of trace metals.
