PAHs Pathways in Stormwater Runoff if Untreated

Stormwater Treatment of PAHs: Why Particle Size Distribution Matters for SuDS Design

Understanding PAHs in Stormwater Runoff Stormwater runoff is a significant pathway for pollutant transport into receiving water bodies. Among these pollutants, Polycyclic Aromatic Hydrocarbons (PAHs) are a main concern in stormwater treatment, due to their persistence and toxicity in our environments. Particle Size Distribution (PSD) aids in determining how PAHs behave- in terms of their […]

Infographhic: Sources of Total Suspended Solids (TSS) in road run off and contaminants that bind to them.

Total Suspended Solids in Road Runoff and Associated Contaminants

What are Total Suspended Solids? In stormwater runoff, Total Suspended Solids (TSS) refers to undissolved solid particles larger than 0.45µm. Anything smaller is considered a dissolved substance. Pollutants can bind to or become trapped within these solid particles, making TSS a highly effective contaminant transport mechanism from surface road runoff into receiving water bodies. In […]

Tyre Wear Paricles in Stormwater Road Run Off - MBT and DPG

Tyre Wear Particles in Stormwater: Why MBT and DPG Chemical Contamination Matters

Tyre wear particles (TWPs) are now recognised as a significant and largely unmanaged source of chemical contamination in urban stormwater. Among the most important tyre-derived chemicals are the vulcanisation accelerators mercaptobenzothiazole (MBT) and diphenylguanidine (DPG), which are used globally to produce durable, heat-resistant rubber. While essential to tyre performance, increasing evidence shows these additives pose […]
