New substances in the database

Within the framework of the Vinnova-funded project Drizzle, StormTac has inventoried and compiled references for the StormTac Database. The project aims to increase and make knowledge accessible through literature searches and data compilation regarding the occurrence of priority and particularly hazardous substances in stormwater, as well as the treatment potential of these substances in conventional stormwater treatment methods.

A literature review has been conducted focusing on case studies investigating pollutant content in runoff from different types of land use, as well as studies presenting data on the treatment performance of various stormwater treatment measures. Previously collected reports and scientific articles have been reviewed and the StormTac Database has been updated with new substances and references.

Data for, among others, the following substances have now been added to the database in the sections for 1) Stormwater (e.g., residential areas, industrial areas, commercial areas, atmospheric deposition, etc.), 2) Baseflow, 3) Surface water, 4) Treatment efficiencies (e.g., biofilters, stormwater drain filters, etc.):

6:2 FTS, As, Ba, BPA, Cd, Co, Cr, Cu, MBT, Mo, N, Ni, oil, P, dissolved P, PAH16, Pb, PFBA, PFBS, PFDA, PFHpA, PFHxA, PFHxS, PFNA, PFOA, PFOS, PFPeA, PFAS 4, PFAS 11, PFAS 24, Sb, SS, V, Zn, 6:2 FTS and MBT.

The compiled data will be continuously updated in the StormTac Database, ensuring that the information is published and made available both nationally and internationally. These results can be used to improve the knowledge base for achieving Environmental Quality Standards (EQS).
