Stormwater runoff contains significant quantities of metal contaminants and is recognised as a major contributor of non-point source pollution in urban aquatic environments. Processes that occur over the course of a storm can control the partitioning of metals between a range of physicochemical forms. Of primary concern are metals that are in a form that is potentially bioavailable to aquatic organisms. To help improve the understanding of this issue, the forms and dynamics of metal contaminants in an urban system were assessed across a storm hydrograph. Whole water samples were collected pre-, during- and post-storm using grab and rising stage sampling methods, and diffusive gradients in thin films (DGTs) were deployed to measure the DGT-labile time-integrated metal concentration. Temporal patterns in the dissolved, total recoverable particulate (TRP) and DGT-labile metal concentrations were assessed, in conjunction with dissolved organic carbon (DOC) concentration and character. In this presentation, the form and dynamics of metal contaminants across a storm will be discussed in the context of water quality management implications. Additionally, the efficacy of using DGT devices to monitor episodic pollution events will also be examined. Outcomes of this presentation aim to provide a foundation for future investigations into the bioavailability and toxicity of trace metals in urban stormwater.
