Abstract

The analyzed samples were runoff waters from bituminous roofing. The runoff water pH was lower than that of the storm-water. First flush phenomena were observable in the samples conductivity, turbidity as well as suspended solid, dry and organic matter concentration. The reason of the phenomena is the initial dissolution of deposited aerosols and weathering products. Because of that, the roof runoff quality is affected by the dry period length. Presumably to the roof matter, the samples had high dissolved organic matter concentrations. The measured polycyclic aromatic hydrocarbon (PAH) concentration implied the dissolution of some component from the roof matter.
