DRIZZLE Lunch Webinars

Autumn 2025

Smarter monitoring and management of stormwater

November 25, 2025, 10:00–11:00
(DRIZZLE in collaboration with Dag&Nät)

In this seminar, Nikita Razguliaev, PhD student at Luleå University of Technology, will present his research on various aspects of data collection, data management, and data use for stormwater management. Particular focus is placed on continuous time series of stormwater quality collected with online sensors. The presentation aims both to raise awareness of possible pitfalls along the path of digitalization and to inspire a broader use of data-driven tools and methods for managing stormwater.

Stormwater sampling in the field – what can we learn from mistakes and challenges?

Within DRIZZLE we have collected stormwater samples at many sites across Sweden. As a rule, we have succeeded in obtaining our samples, but the road there has sometimes been filled with challenges and unforeseen problems. Godecke Blecken, Professor at Luleå University of Technology, summarizes and describes what can happen when sampling stormwater in practice, and how one can eventually achieve a successful outcome.

Effect-based toxicity testing of stormwater and stormwater sediments

In this seminar, Snezana Gavric, Postdoctoral researcher at Luleå University of Technology, discussed her results on the potential biological effects of exposure to runoff from roofs made of different materials. Haoyu Wei, Postdoctoral researcher at Luleå University of Technology, presented his research on the biological effects of sediments from stormwater ponds and compared the results with chemical analyses.

Metal concentrations variations in urban runoff from various land use types in Sweden

Franz Geronimo, Postdoctoral researcher at Luleå University of Technology, presented results on metal concentrations in urban runoff. The seminar showcased findings from 15 study sites across seven Swedish cities and municipalities. In particular, the impact of base flow on stormwater quality in urban areas was presented.

Mapping PFAS in stormwater

In this seminar, Hannah Johansson, industrial PhD student at Växjö Municipality/Water and Wastewater Engineering, Luleå University of Technology, presented her research on PFAS in stormwater from six Swedish cities. She described the occurrence and variation of PFAS substances found in stormwater facilities and other stormwater occurrences, as well as the variation depending on different land uses and catchment areas.
