Organic Micropollutants, Metals and Total Suspended Solids in Urban Stormwater Runoff from an Industrial Area
Particulate matter has been considered an indicator for the pollution of urban stormwater runoff for quite some time. There are only few studies that have investigated the contamination with organic micropollutants and metals both in the dis-solved and particulate phase as well as across different particle size classes. Yet, this distribution plays an important role in better understanding and optimising urban stormwater treatment measures. Therefore, this work aimed at assessing the composition of particulate matter in urban stormwater in terms of the physico-chemical properties (particle size distribution and organic content), as well as the occurrence of organic micropollutants and metals, their association to particulate matter and their removal from urban runoff. An intensive long term monitoring campaign at a centralised stormwater treatment facility of an industrial area was conducted. The stormwater runoff was sampled with large volume sampling tanks filled volume-proportional to the runoff at the two outlets of the facility. This allowed the determination of the event mean concentrations as well as the load-related removal efficiencies of the treatment facility for different parameters. Within each sample the concentrations of total suspended solids across different particle size fractions (< 63 µm, 63 – 125 µm, 125 – 250 µm, 250 – 2000 µm) were measured as well as their organic content. Furthermore, the concentrations and the phase distribution of 5 metals (Chromium, Copper, Zinc, Cadmium, Lead) and 29 organic micropollutants including polycyclic aromatic hydrocarbons, industrial chemicals (e.g. organophosphates, alkyphenols) and biocides were ana-lysed across different particle size fractions. In this study, over a period of almost 2.5 years, a total of 36 sampling events were recorded and investigated within two sampling periods (2015 – 2016 and 2017 – 2019) at the rainwater treatment facility in Freiburg Haid. The occurrence of organic micropollutants was determined in 22 of these events and the ...
